The present invention relates to techniques for the formation and processing of radio signals.

Known apparatus for forming copies of the signal (patent 4128759 USA, MCI N 04 009/00)containing the transmitting optical module (POM), N optical fiber delay lines (VOLGA) in the form of segments of the fibre (SC) of different lengths and a photodetector (PD). The optical signal from the optical output POM, electrical input which is the input device, is fed to harness formed by the input ends N the VOLGA, with the output ends of which optical radiation is fed to the optical input of the photodetector, the electrical output of which is an output device. The formation of copies is due to the delay of parts of the optical radiation at different times in different VOLGA and their subsequent summation in the photodetector.

Signs of similar matching the features of the proposed technical solutions are POM, N the VOLGA, the photodetector.

The drawbacks are the inability to control the sequence generated copies, as well as high return loss input optical radiation from POM to the input ends of the optical fibers of the VOLGA.

The obstacles to achieve the desired technical result is the lack of resources to manage the process of duplicating the input signal is La, as well as that for the formation of M copies of the input signal with a repetition period τ_assyou must use M fiber optic cable with a total length of about 0.5· M²·L that M/2 times the length of the aircraft in the claimed object (where L is the length of the aircraft, providing the delay τ_ass).

The known range of the recirculating storage devices on the basis of the VOLGA, in which the formation of copies of the signal is due to the branching of the optical radiation in the recirculation loop, representing a segment of the fibre of a given length.

In the patent 4473270 USA, MCI G 02 B 005/172 described device containing the SIP, a directional fiber coupler (NVO) X-type, the VOLGA in the form of a segment of the armed forces and photo detector. Optical output POM, electrical input which is the input device, connected to the first input port NVO X-type, the third output port through which the VOLGA with time delay τ_assconnected to the second input port NVO X-type. The fourth output port NVO connected to the optical input of the photodetector, the electrical output of which is the output device.

Signs of similar matching the features of the proposed technical solutions are POM, the VOLGA, the photodetector.

The drawbacks of such devices is the inability to control is the selected form of copies, high non-identity of copies due to attenuation in the armed forces from copy to copy, and in connection with the serial output of the optical radiation from the recycling process, as well as the accumulation of noise during recirculation of the signal.

The obstacles to achieve the desired technical result is the lack of resources to manage the process of duplicating the input signal, and the attenuation of the signal from copy to copy in connection with the serial output of the energy of optical radiation from the circulation process. As a result, when a constant noise level of the photodetector signal-to-noise copies of the output devices and their levels decrease very rapidly, which ultimately causes a small time information storage and high non-identity copies.

The known device dynamic memory based on the reflection of the VOLGA, in which the formation of copies at the expense of the branch portion of the optical radiation through a certain distance using a special branches.

In the patent 4558920 USA, MCI G 02 B 005/172 described device containing the SIP, tap the VOLGA in the form of a wound on the drum TU, the optical rod and the photodetector. The input device is the electrical input of the SIP, the optical output of which is connected to the input of the VOLGA, and radiation from bends SU wound bar on the ban, projected into the spliced with the main fiber by removing the sheath at his side optical terminal, the output of which arrive at the optical input of the photodetector, the electrical output of which is the output device.

Signs analogues, coinciding with the features of the proposed technical solutions are POM, the VOLGA, the photodetector.

The disadvantages of the known devices is the inability to control the sequence generated copies, small storage information, as well as the complexity of manufacturing, high consumption of the fibre and the uneven level of copies of the output.

The obstacles to achieve the desired technical result is the lack of resources to manage the process of duplicating the input signal and that of the technological considerations coefficients branch optical radiation from the taps of the fibre are the same. In this case, due to the successive branching of the optical signal amplitude of the output signals of the device with the growth in the number of copies is reduced and the more noticeable, the higher the ratio of branches.

In the device described in the patent 4557552 USA, MCI G 02 B 005/172 applied POM, tap the VOLGA in the form of a wound on the drum TU, two lens and the photodetector. The entrance is trojstva is electric entrance POM, the optical output of which is connected to the input of the VOLGA, and the optical radiation may be partially out of the sun on a specially made bends, which is then focused by the first and second lenses and fed to the optical input of the photodetector, the electrical output of which is the output device.

Signs analogues, coinciding with the features of the proposed technical solutions are POM, the VOLGA, the photodetector.

The drawbacks of such devices is the inability to control the sequence generated copies, high non-identity of copies due to attenuation in the armed forces from copy to copy, and in communication with the output optical radiation from the aircraft, as well as the complexity of manufacturing.

The obstacles to achieve the desired technical result is the lack of resources to manage the process of duplicating the input signal and that of the technological considerations coefficients branch optical radiation from the taps of the fibre are the same. In this case, due to the successive branching of the optical signal amplitude of the output signals of the device with the growth in the number of copies is reduced and the more noticeable, the higher the ratio of branching. The desire to ensure uniformity level copies of the signal at the output C is a sequence of increasing ratios of branching involves the use of unique technological equipment and instrumentation, as well as the complexity of the design and dimensions of the device.

Known technical solutions closest to the technical essence is a dynamic storage device of the radio signal with a controllable binary optical fiber structure (patent 2213421 EN, IPC⁷N 04 10/00, G 02 In 6/00, G 01 S 7/40).

Dynamic storage device with a controllable binary optical fiber structure includes a broadband amplifier SHU, power divider DM, the transmitting optical module POM, fiber-optic amplifier HEU, the photodetector PD, the control unit BU, and dividing NVO Y-type, 2N fiber-optic keys BOK₁...BOK_2NN fiber-optic delay lines the VOLGA₁...The VOLGA_N, (N-1) NVO X-type HBO₁...HBO_N-1and summing NVO Y-type.

The input device is the input of the broadband amplifier SHU, the output of which is connected to the input of the power splitter DM, the first output of which is connected to the electrical input of the SIP, the optical output of which is connected to the optical input of the optical fiber amplifier HEU, the optical output of which is connected to the input port of the separation NVO Y-type, the first output port which is connected to the optical input BOK₁, the optical output of which is connected to the first input port of the first IEE Htype HBO ₁the third output port of which is connected to the optical input of the SAI₂, the optical output of which is connected to the first input port of the second IEE X-type NVO₂and so the Third output port of the last (N-1)-th NVO X-type NVO_N-1connected to the optical input of the SAI_N, the optical output of which is connected with the first input port of summing NVO Y-type, the output port of which is connected to the optical input of the photodetector PD, the output of which is an output device. The second output port of the separation NVO Y-type is connected to the optical input BOK_n+1, the optical output of which through the VOLGA₁connected to the second input port of the first NVO X-type hbo₁the fourth output port of which is connected to the optical input BOK_N+2, the optical output of which through the VOLGA₂connected to the second input port of the second IEE X-type NVO₂and so the Fourth output port of the last (N-1)-th NVO X-type HBO_n-1connected to the optical input BOK_2N, the optical output of which through the VOLGA_Nconnected to the second input port of summing NVO Y-type. The second output of power divider DM is connected to the input of the control unit BU, outputs 1, 2,... , 2N of which are respectively connected to the control inputs of fiber-optic keys BOK₁...BOK_2N.

The principle of operation of the device is the STV is the following. The input signal is amplified in a wideband amplifier SHU to the required level and through the power splitter DM is supplied to the transmitting optical module NOM, which converts the radio signal in the modulated radiation in the optical range. Next, the optical signal through a fiber-optic amplifier HEU is applied to the input port of the separation NVO Y-type. The further path of propagation of optical radiation and, accordingly, the time delay depends on the status of all fiber-optic keys BOK₁...BOK_2N. The principle of forming copies when no control over copies (all wok closed), is the following. Zero-copy input signal corresponds to direct transmission of optical radiation from the input port of the separation NVO Y-type output port summarizing NVO Y-type, bypassing all the VOLGA. The first copy of the signal generated through branch in the separation NVO Y-type part of the optical signal in the VOLGA₁(via closed wok_N+1time delay τ_ass. With the release of the VOLGA₁radiation enters the second input port of the first NVO X-type HBO₁and without further delay at the output port of the summing NVO Y-type. When forming a second copy of the optical signal is delayed only in the VOLGA₂. The third copy of the signal is generated and due to the delayed modulated optical radiation as in the VOLGA ₁and in the VOLGA₂. Finally, the last M-I a copy of the input signal passes through all the VOLGA with the total delay time Mτ_ass=(2^N-1)τ_ass. Wealth management BOK₁...BOK_2Nusing the control unit BU allows to include in the General path of optical radiation certain VOLGA and thereby to form copies of the input signal with different delay times. The minimum delay time obtained when the fiber-optic switches are in such a state that the optical signal does not pass through any of the VOLGA, and the maximum delay time - when optical radiation is delayed in all of the VOLGA. Output summing NVO Y-type optical signal to the input of the photodetector, which performs the inverse transform of the modulated radiation in the optical range in the radio signal, which is supplied to the output device.

Works dynamic storage device (DZU) serial binary optical fiber structure (VOS) as follows (see figure 1 and 2).

Dynamic storage device are used to form a time sequence of M+1 copies

complex signal duration τ_and

The parameter K_iU_cdetermines the amplitude of the i-th copy of broadband microwave signal with amplitude m_c(t) and/or angular f_c(t) modulation. The choice of the repetition period (delay time) copies τ_ass>τ_andeliminates the possibility of temporal overlap of individual copies.

Variant i=0 in the formula (1) corresponds to direct transmission of the input signal (2) to exit the COUNTRY without delay. In this case we speak about the formation of a DZU zero copies of the input signal.

The principle of forming a copy of the input signal in DZU binary VOS in the case when no control over copies (all wok closed) is as follows (see figure 1). Zero-copy input the nogo signal corresponds to direct transmission of optical radiation from the input port of the separation NVO Y-type 7 to the output port of the summing NVO Y-type 11, bypassing all the VOLGA. The first copy of the signal generated through branch in the separation NVO Y-type 7 of the optical signal in the first VOLGA 9-1 (through a closed (N+1)-th SAI 8-(N+1)) with time delay τ_ass. With the release of the first VOLGA 9-1 radiation is supplied to the second input port of the first VOCP 10-1, the first output port of the first VOCP 10-1 and forth without delay to the output port of the summing NVO Y-type 11.

When forming a second copy of the emitted POM 3 the signal is transmitted by the circuit input port of the separation NVO Y-type 7 - first output port of the separation NVO Y-type 7 - closed first wok 8-1 - first input port of the first VOCP 10-1 - second output port of the first VOCP 10-1 - closed (N+2)-th SAI 8-(N+2) - the second VOLGA 9-2 second input port of the second VOCP 10-2 - first output port of the second VOCP 10-2 and without further delay the output port of the summing NVO Y-type 11. The third copy of the signal generated due to the delayed modulated optical radiation as in the first VOLGA 9-1 and the second VOLGA 9-2. Finally, the last M-I a copy of the input signal passes through all the VOLGA with the total delay time Mτ_ass=(2^N-1)τ_ass.

Thus, if all the wok shorted, the output DZU N the VOLGA is formed by a sequence of 2^Ncopies (including zero) of the input signal (the General succession of alnost).

Fiber-optic amplifier HEU 4, mounted at the output of the transmitting optical module POM 3, necessary to compensate for optical radiation in a serial binary VOS and a given gear ratio of the device.

The control unit BU 6 works as follows (see figure 3 and 4). To the input of the control unit from the second output of the power splitter DM 2 receives an input signal u_who(t) duration τ_andthat increases in broadband amplifier SHU 12. With the amplifier output amplified signal u_why(t) is input to the pulse shaper PHI 13, the output of which in the time of arrival of a radio signal is generated video impulse u_WiFi(t) duration τ_and. As a shaper pulses PHI 13 may act as a threshold device, triggered by excess input signal of a certain level. Formed in the pulse shaper PHI 13 video impulse is supplied to the first inputs of the logic elements "AND" LI1 15 and LI2 16.

The output signal from the pulse shaper PHI 13 is also fed to the clock input of the control keys UIC 14, the information input which receives a digital control code sequence generated copies. Digital control code can be specified using a 2N electrical key is th, each of which will manage the relevant wok and using more sophisticated tools, such as a computer. In this case, information about the arrival time and duration of the input signal is transmitted to a control device keys UIC 14 using the signal output from the pulse shaper PHI 13.

Digital control code is converted in the control unit keys UIC 14 in the control signals each wok separately and served as control signals for the wok on the second, third, ... , nth, (N+2)-th, (N+3)-th,... , 2N-th outputs of the control unit BU 6 directly, and on the first and (N+1)th outputs of the control unit BU 6 through logical elements "AND" LI1 15 and LI2 16. In logical elements "AND" LI1 15 and LI2 16 are combined output signal of the pulse shaper PHI 13 and the first and (N+1)-th output control keys UIC 14, and the corresponding wok will be opened only in the case when both inputs of the respective logic element "And" will be the signal for opening the SAI.

The use of logical elements "AND" LI1 15 and LI2 16 it is necessary to first wok 8-1 and (N+1)-th SAI 8-(N+1) even in the absence of control copies were opened only at the time of arrival of the signal and only at the time of its duration (under the influence of control signals u₁(t) and u_N+1(t) in figure 2), which does not Boo who should be allowed the passage of the noise input stages of the device at its output and the accumulation of noise in binary VOS during the formation of the copies of the input signal.

Advantage DZU binary VOS over DZU other species is that all copies of the signal pass through the same number of ports HBO and compounds of the fibre, thereby ensuring equal loss of optical radiation for all copies. Non-identity generated copies is determined only by the losses due to different lengths of the optical fibers used in the VOLGA.

Own loss of optical radiation in optical fibers due to the production technology and are specified in the technical specifications. Minimal loss of intensity of optical radiation have single-mode fiber fiber type quartz-quartz, the working wavelength of which is λ 1.55 microns. A typical value of linear attenuation (loss) of optical radiation for this type of optical fibers of domestic production is G_sun=0.2 dB/km

A segment of the armed forces for the j-th VOLGA will have losses

α_c.j[dB]=L_j[km]· G_sun[dB/km]=2^j-1·L₁[km]· G_sun[dB/km],

where L_j=2^j-1·l₁- the length of the armed forces for the j-th VOLGA;

- the length of the fibre, providing a delay of optical radiation at the desired time τ_ass(cut optic lights is Yes to the first VOLGA);

C=3× 10⁸m/s is the speed of light in vacuum;

n_c=1,465 - core refractive index of the fibre.

Design requirements for the VOLGA involve winding the fiber on a reel with a diameter of D_cat. When this ring bending of the fiber causes additional losses in the intensity of optical radiation.

If the loss of one coil are α_round, the loss of intensity of optical radiation in the coil j of VOLGA will be

wherethe number of turns of the fibre length L₁(the first VOLGA)wound on the coil diameter D_cat.

Thus, the total loss in the j-th VOLGA will be:

α_.j[dB]=α_.j[dB]+α_.j[dB]≈ 2^j-1·(L₁[km]· G_sun[dB/km]+In_{1α round}[dB])

Maximum non-identity generated copies Δ P, characterizing the difference in the powers of copy with a maximum amplitude of the P_maxand copies of the minimum amplitude of the P_minis the sum of the losses of optical radiation in all N the VOLGA:

The factor 2 in front of the sign of the sum in this expression shows that the electric power of the signal is proportional to the square of the intensity of choice for the definition of radiation.

The results of the calculation of the identical form of copies in DZU binary VOS for different numbers of the VOLGA N presented on Fig.7. The calculations were performed for the case when τ_ass=0,1 µs (L₁≈0,02 km), G_sun=0.2 dB/km α_round=0,0001 dB, D_cat=250 mm (B₁≈25). For calculations it is also expected that this device uses the so-called 3-decibelle NVO, the transmission ratios which are equal and equal to 0.5 (≈ -3 dB).

In the case of forming a sequence of 16-and copies with a latency period of τ_ass=100 NS, the difference in the capacities of the first and last copies is just 0,201 dB. But it should be noted that with the increase in the number of generated copies of this difference increases dramatically. So, at 128 and copies with the same time delay τ_ass=100 NS non-identity generated copies will be already 1,703 dB, and when 1024-x - 13,71 dB.

The claimed technical solution can achieve much higher identity generated copies of the signal, if the losses in the j-th VOLGA connected through (N+j)-th wok to 2nd output port (j-1)-th VOCP, to compensate for the fact that the fiber light guide the VOLGA to forkpart of the optical radiation received at the input ports of VOCP.

To ensure that this t is bowenia of the claimed technical solution changed structure of binary VOS: each NVO X-type, used in the prototype (smfh), the claimed technical solution is replaced by fibre-optic quadrupole, each of which represents a connected in series internal summing and dividing NVO Y-type (smfg).

A directional fiber coupler X-type (figa) is characterized by the ratio of branch k<1, which understand the transmission coefficient of optical radiation with 1 input port 2 output port To₂₁or equal to the transmission coefficient of optical radiation from the 2nd input port 1 output port K₁₂

To₂₁=K₁₂=k.

The transmission coefficient of optical radiation with 1 input port 1 output port or the transmission factor of the optical radiation from the 2nd input port 2 to be the output port for NVO X-type will be equal to

K₁₁=K₂₂-(1-k).

Thus, in NVO X-type for increasing the optical radiation branch 1 input port 2 output port that is connected to the VOLGA, it would be necessary to increase the k-factor. However, this would lead to a corresponding reduction of the coefficient of transmission of optical radiation from the 2nd input port on the same 2-th output port (1-k), which contradicts earlier put forward the claim for compensation of losses in the VOLGA.

Meeting this requirement can be Dostiev case of replacement of each tap X-type fiber-optic quadrupole, representing a serial connection summing and dividing couplers Y-type (figb).

In this case, summing NVO Y-type that is part of VOCP, are combined optical radiation from the 1st and 2nd input ports of summing NVO Y-type (1st and 2nd input ports of VOCP), and then the resulting amount is divided between 1-mi 2-m output ports included in VOCP separation NVO Y-type (1-mi 2-m output ports of VOCP) with the specified value. The increase in the branching ratio k (see figb) will lead to an increase in the fraction of optical radiation received at the 2nd output port of VOCP as from the 1st and 2nd input port of VACP and a corresponding decrease in the proportion of optical radiation, incoming from the input ports of VOCP 1-th output port of VOCP.

It should be noted that in real taps are always present loss of light energy, which is expressed in the fact that the total radiation intensity at the output ports IEE does not match the intensity of the input radiation. These losses are usually calculated parameter γ_NVOand are of the order of 0.1 dB.

For full compensation of losses in the j-th VOLGA it is necessary that the intensity of optical radiation J_(j-1).wyhon the 2nd output port (j-1)-th VOCP surpassed the intensity of the optical radiation j_(j-wij on the 1st output port of the same VOCP on the amount of losses in the j-th VOLGA α_.j

While the ratio of branch k_(j-1)internal dividing NVO Y-type, part of the (j-1)-th VOCP must satisfy the condition

In this case, you will be provided full identity generated copies.

It should be noted that expression (4), (5) are valid for the case of j>1. To compensate for losses in the first VOLGA (this corresponds to the case j=1), it is necessary to change the ratio of the branch separating NVO Y-type 7 that is installed on the input serial binary VOS (see figure 1).

Coefficient junction separation NVO Y-type 7 that is installed on the input serial binary VOS, which will occur the losses of optical radiation in the first VOLGA, must satisfy the following condition:

In this expression to simplify the notation coefficient branches dividing NVO Y-type 7 is designated as k₀.

Currently there are several types of HBO and methods of their manufacture on the basis of fiber, microplanar and planar technologies.

For the manufacture of HBO on the basis of optical fibers are widely used fusion, precision fur the systematic processing and chemical etching with subsequent restoration of the shell. For example, the chemical method of manufacture of taps fiber lightguides clear of the protective membranes, bind cleared areas and carry out the etching of the reflective membranes. After reaching the predetermined transmission ratios, controlled by the output signal directly in the etching process, the fibers are washed and carried out restoration of the shells.

All methods of manufacturing NVO-based fibers provide low optical loss of about 0.1 dB and set the coefficients of the transfer.

It should be noted that the replacement of each NVO X-type fiber-optic two-port network consisting of two NVO Y-type will lead to some increase in losses in binary VOS due to the additional connection of the output port of the summing NVO and the input port of the separation HBO are included in every VOCP, as well as additional losses to the passage of two NVO Y-type instead of one NVO X-type. The losses increase slightly and will be about 0,2... 0,4 dB at each stage.

For an absolutely precise conditions (4) and (5) it is necessary to make NVO with a very high degree of accuracy (Fig.9), which may be unattainable in practice (case j=1 corresponds to the calculation of the desired ratio of branch k₀dividing NVO Y-type 7 installed on in the ode consistently binary VOS).

However, a significant increase in identity generated copies can be achieved and not as hard constraints. Calculations show that when performing a coefficient of variation HBO with an accuracy of 0.001 for binary VOS 5 the VOLGA non-identity generated copies will be only 0,0462 dB (when the coefficient of variation of all HBO 0.5 non-identity of copies is equal to 0,416 dB).

Be aware that when you change the coefficients branch NVO definition of identical, formed of a sequence of copies by the formula (3) is impossible. To find the identical in this case, you must select the signal at the output binary VOS copies with the maximum and minimum amplitudes (this is not necessarily zero and the last copy, respectively) and to find their attitude

For DZU N-cascaded binary VOS amplitude intensity of optical radiation m-th copy of the output VOS can be found by the formula

where J_c- the intensity of the optical radiation at the input binary VOS;

- coefficient characterizing the loss of optical radiation used in each of IEE (loss scattering of radiation into the surrounding space γ_NVOand the loss of connection is volokonnogo fiber ports NVO ξ _NVO).

The transmission coefficient of the j-th cascade serial binary VOS

depends on the route of the optical signal through binary VOS (from non-generated copies of m). Here- transfer coefficient j of the VOLGA, and k_(j-1)-coefficient of branches separating PVO Y-type that is included in the (j-1)-th VOCP for j>1, or the ratio of branch k₀dividing NVO Y-type 7 that is installed on the input serial binary VOS, for j=1.

determines whether passes the optical signal through the j-th VOLGA during the formation of the m-th copy of the signal (if a_m,j=0, the optical signal does not pass through j-th VOLGA; if a_m,j=1, then, on the contrary, the formation of the m-th copy of the optical signal must stay in the VOLGA j-th cascade). Function trunc(x) denotes the nearest integer not exceeding X.

Figure 10 shows the enlarged view of the generated output serial binary VOS sequence of copies of the input signal in the case of 5-and VOLGA when all of the IEE with a coefficient of variation of 0.5 (copy signal is conventionally shown as solid rectangles). To improve clarity, the figure held the line of the maximum and minimum amplitudes of copies. The figure axis of ordination the amplitude of the intensity of optical radiation copies the normalized relative intensity of optical radiation at the input binary VOS (J_m/J_c).

As can be seen from the figure, the maximum amplitude has a zero copy (J₀=0,011354J_c), the minimum amplitude is the last copy (J₃₁=0,010823J_c). Non-identity copies Δ P in this case is 0,416 dB.

The greatest influence on the identity of copies of my losses in the past, the 5th, the VOLGA (0,1072 dB), as it has the greatest length of the fibre. To compensate for these losses, it is necessary that the ratio of the branching part of the fourth VOCP separation NVO Y-type was equal to k₄=0,5061739 (or when HBO with an accuracy of 0,001 - k₄≈0,506). In this case, 5 the VOLGA will branch out the greater part of the optical radiation that will lead to some increase of the amplitudes of copies, the formation of which they linger in the 5th VOLGA, i.e. copies with numbers 16... 31 (figa).

Thus there is a decrease in the maximum amplitude of copies (J_max=J₀=0,011210 J_cand the increase of the minimum amplitude of copies (J_min=J₃₁=0,010946J_c), which reduces the identical to Δ P=0,2071 dB.

To compensate for the losses in the 4th VOLGA necessary coefficient branches dividing NVO Y-type, part 3-Guo VOCP, to perform equal to k 3≈0,503. This will cause an increase of the amplitudes of copies with numbers 8... 15, 24... 31 and the reduction of the amplitudes of the remaining copies, which will also lead to some increase in identity generated copies (figb).

Thus there is a further reduction of the maximum amplitude of copies (J_maxJ₀=0,011143J_cand the increase of the minimum amplitude of copies (J_min=J₃₁=0,011016J_c). Non-identity of copies in this case is Δ P=0,1029 dB.

If you run coefficient branches dividing NVO Y-type, part of the 2-th VOCP approximately equal to k₂≈0,502, there will be compensation for loss of optical radiation in the 3rd VOLGA, which would also affect the form of a generated sequence of copies: the amplitude of those copies that stay in 3rd VOLGA(4... 7, 12... 15, 20... 23 and 28... 31) will rise, others will fall (pigv).

It should be noted that in this case, the maximum amplitude is not already zero, and the 4th copy (J_max=J₄=0,011119J_c), the minimum amplitude is not the last, and the 27-I copy (J_min=J₂₇=0,011036J_with). Non-identity generated copies is already Δ P=0,0651 dB.

Finally, when the compensation of losses in all the cascades (run coefficients branch, part of VOCP separation NVO Y-type according to figure 9 with an accuracy of 0.001) the difference is between the maximum and minimum amplitudes of the copies will become even less significant (J _max=J₆=0,011106J_withand J_min=J₂₅=0,11047J_c). View formed of a sequence of copies of the output binary VOS for this case is shown in Figg.

Non-identity generated sequence copies will be Δ P=0,0462 dB, i.e. the maximum amplitude of copies exceeds the minimum amplitude just 1,005337 time.

On Fig the results of calculations of the identical form of copies of the signal in the manufacture of HBO with transmission ratios made with a precision of 0.1; 0.01 and 0.001. Graphically the dependence of the identical form of copies at different accuracy coefficients branch NVO from the number of the VOLGA N presented on Fig.

Proposed measures to enhance the identity generated copies DZU-based binary VOS significantly improve the conditions of reproduction of the input signal. So, for example, in this device it will be possible the formation of 4096 copies with eidetically not exceeding 0.2 dB (in the absence of such measures non-identity of copies, not exceeding 0.2 dB, can be obtained only when the 16 copies).

It must be recognized that the proposed measures are effective when the number of the VOLGA, not exceeding 10... 13 (depending on the accuracy of manufacturing NVO). If larger number of the VOLGA loss in the fiber light guide is reach values you are unable to compensate for the change of the coefficients of the branches of the NVO. To enhance the identity of copies in this case, by setting consistently with the VOLGA optical amplifiers required to compensate for gain.

Thus, the results of this research show that the claimed technical solution due to the replacement of NVO X-type is connected in series summing and dividing NVO Y-type, and odds changes branches dividing NVO Y-type can greatly improve the identity generated copies the specified number of copies or to increase the number of copies when required identical compared to the prototype (patent 2213421 EN, IPC⁷N 04 10/00, G 02 B6/00, G 01 S 7/40). This proves the existence of a causal connection between the claimed combination of features and technical result in the increase of identity generated copies.

To prove the possibility of managing the process of forming copies will consider the process of replication of the input signal in dynamic storage devices sequentially binary optical fiber structure.

Consider first the process control sequence generated by the device copies when used for these purposes, only the first N wok 8-1,... , 8.

When opened, the j-th optical fiber key wok 8-j of the General sequence of copies will disappear first 2^j-1copies. Subsequent 2^j-1copies will easily pass to the output DZU, etc. Thus, if the availability of copies of the output device through the "1"and the absence - through "0", the generated private sequence copies when opening, only the j-th optical fiber key BOK_jcan be represented as a binary word S_jlength 2^Ndigits

So, by opening only the first optical fiber key wok 8-1 of the General sequence of copies will only copy with odd N numbers: 1, 3, 5,... , 2^N-1, that is, delay time copies τ_ass, 3τ_ass, 5τ_ass,... , (2^N-1)τ_assrespectively. Similarly, by opening only the second wok 8-2 of the entire sequence of copies will only copy with delay times 2τ_ass, 3τ_ass; 6τ_ass, 7τ_ass;... ; (2^N-2)τ_ass, (2^N-1)τ_ass. Finally, when opened, only the N-th key wok 8-N private sequence generated copies will contain copies of delay times (2^N-1)τ_ass, (2^N-1+1)τ_ass,... , (2^N-1)τ ass.

With the simultaneous opening of two or more keys in a binary VOS view the generated private sequence can be easily obtained by bitwise multiplication of binary words corresponding to the opening of each of the considered key separately.

Control copies DZU N the VOLGA and binary VOS when used to control only the first N wok 8-1,... , 8-N, allows you to:

1) increase the repetition period of copies in 2, 4, 8,... , 2^N-1times;

2) to form packages of copies in the number 2, 4, 8,... , 2^N-1pulses;

3) to change the pause between the generated copies and packets of copies (pause equivalent to the time of formation 2, 4, 8,... , 2^N-1pulses);

4) create only one copy with the delay time (2^N-1)· τ_ass.

The number of copies of X_kobtained by the simultaneous opening of k keys (when using N the VOLGA), is defined by the expression

X_k=X^N-k.

The number of possible combinations of X_k,Nat the same time open key number k when the total number N can be determined by the formula

The total number of possible combinations of dead keys when used to control only the first N wok 8-1, (8-N and, therefore, variants of the sequences of copies of X_Nwill be equal to

Much greater control sequence generated copies will be obtained if used for these purposes, all wok 8-1,... , 8-2N.

In this case, the proposed solution allows you to:

1) by changing combinations of open wok, you can change the relative location in time (change the numbers) generated copies of the signal while maintaining the same species sequence;

2) while opening the j-th SAI 8-j and (N+j)-th SAI 8-(N+j), the formation of copies is impossible ("off" DZU without changing modes all core modules).

Various combinations of dead keys allow you to change the relative locations of generated copies at the same as their sequence. Interest is the change of location in the case of forming only one copy of the various combinations of dead keys allow you to obtain a copy of any sequence number.

The number of different variants of otnositeljnoyj locations generated sequences of copies of k open keys with preset numbers equal to

Y_k=2^k.

The total number of possible options for different sequences of copies (including different locations) for DZU N the VOLGA is determined by the expression

On Fig shows the results of the formulas (9) and (10) payments options received copies.

For example, DZU with a managed binary VOS using three of the VOLGA (N=3), the formation of 27 different sequences of copies. All data variants of the sequences presented on Fig.

Thus, the claimed technical solution allows you to create a temporary sequence of the 2^Na copy of the input signal with a repetition period τ_assand due to the possibility of process control replication:

1) increase the repetition period of copies in 2, 4, 8,... , 2^N-1times;

2) to form packages of copies in the number 2, 4, 8,... , 2^N-1pulses;

3) to change the pause between the generated copies and packets of copies (pause equivalent to the time of formation 2, 4, 8,... , 2^N-1pulses);

4) to change the relative location in time (changing rooms) generated copies of the signal while maintaining the same sequence;

5) to form one copy of any number (latency 0,... , τ_ass; 2τ_{for the} ,... , (2^N-1)· τ_ass).

The proof of the retention of small flow rate of the fibre in the inventive object is given below.

For the formation of M copies of the input signal with a repetition period τ_assin the device described in the patent 4128759 USA, MCI N 04 009/00 (see Fig), using M fiber optic cable with a total length of about 0.5· M²·L that M/2 times the length of the aircraft in the claimed object (where L is the length of the aircraft, providing the delay τ_ass).

The recirculation device fiber-optic memory described in patent 4473270 USA, MCI G 02 B 005/172 (see Fig), have the lowest consumption of the fibre, which is determined by the repetition period of copies. However, these devices are characterized by high attenuation of the signal from copy to copy in connection with the serial output of the energy of optical radiation from the circulation process. As a result, when a constant noise level of the photodetector signal-to-noise copies the output of such devices is rapidly decreasing, which ultimately causes a small time information storage and high non-identity copies.

The total length of the fiber in dynamic memory devices based on reflection the VOLGA described in patents 4558920 USA, MCI G 02 B 005/172 (see Fig) and 4557552 USA, MCI G 02 005/172 (see Fig), as in the claimed object is proportional to the number of generated copies.

Dynamic storage device with binary VOS (patent 2213421 EN, IPC⁷N 04 10/00, G 02 In 6/00, G 01 S 7/40) (see Fig) is characterized by the same factors affecting the consumption of the aircraft, and that the claimed object.

The analysis proves the existence of a causal link between the claimed combination of features and achievable technical result in conservation of small flow rate of the fibre.

Functional elements of dynamic memory devices managed binary optical fiber structure and the device in General (smpeg) satisfy the criterion of industrial applications.

With respect to schema elements DZU 1-5, 7-11 (see figure 1) the following can be noted. The industry has mastered and serially produces a fairly wide class of semiconductor laser emitters and transmitting optical module for wavelength (from 1.3 to 1.55 microns), capable of working in single-mode at room temperature and with acceptable consumer characteristics. In particular, the transmitting optical module POM-13M has the following basic data (Strokea OF, Bezborodova T.M. Products fiber optic technology: Directory. - M.: ECOS, 1993. - 142 S.): the wavelength of 1.3... of 1.55 μm, the power irradiation is s 1 mW, the width of the envelope of the spectrum of 0.01 nm, the transmission rate of 5 Gbps, single-mode generation.

The bandwidth of a modern single-mode fiber up to 100 GHz km or more to the group delay of the signal on the order of 5 µs/km and dispersion at the wavelength of 1.3 μm is not more than 3.5 PS/(nm km) (A. N. Bratchikov. Fiber-optic delay line broadband radio signals // Foreign Radioelectronics. - 1988. No. 3. - P.85-94).

Among domestic fiber-optic amplifiers can be noted OA-850 and OA-1300 with gain K_HEUequal to 6 and 10 dB when the input signal level 20... 100 µw (manufacturer research Institute "Volga" NGOs "Reflector") and single-mode fiber-optic amplifier at a wavelength of 1.53 1.55 um... (cooperative Fiberoptic"). Company "Pirelli CAVI SPA" (Italy) offers optical amplifier "AMPLIPHOS" erbium-doped fiber operating in the optical range λ =1530... 1560 nm for optimal amplification of W_HEU=22... 30 dB, noise figure_HEUdo not exceed 4 dB.

Currently, there are different types of fiber-optic keys. Mechanical wok are characterized by low optical loss (0,5... 1 dB), the power of a few milliwatts and low response time (10... 50 MS), which is their main disadvantage. Fiber-optical is the cue switches on liquid crystals have no moving parts and potentially more reliable than the mechanical. Optical losses in this type of wok is 1... 2 dB, input power 30... 50 µw and the switching speed 5... 50 MS. The acousto - optical wok on three-dimensional elements provide the switching speed of about 10^-6with^-1have a level of optical loss 2... 3 dB. Electro-optical switches on a single-mode strip waveguides have optical losses, including losses in connection with fiber optic cable about 2... 3 dB, the switching speed of up to 6 GHz and control voltage 4... 10 Century

Currently there are several types of HBO and methods of their manufacture on the basis of fiber, microplanar and planar technologies. For the manufacture of HBO on the basis of optical fibers are widely used fusion, precision machining and chemical etching with subsequent restoration of the shell. For example, the chemical method of manufacture of taps fiber lightguides clear of the protective membranes, bind cleared areas and carry out the etching of the reflective membranes. After reaching the predetermined transmission ratios, controlled by the output signal directly in the etching process, the fibers are washed and carried out restoration shells. All methods of manufacturing NVO-based fibers provide low optical is Oteri about 0.1 dB and set the coefficients of the transfer.

Photodetecting devices are typically a combination of a photodiode and a cascade of pre-amplification signal of the photoresponse. The maximum bandwidth of detected signals serial photodiodes reaches 5... 10 GHz with a sensitivity of intensity of optical radiation of the order of 30 dBm, dynamic range 20... 25 dB and the steepness of the characteristics of detection of 0.5... 0.8 a/W current (Strokea OF, Bezborodova T.M. Products fiber optic technology: Directory. - M.: ECOS, 1993. - 142 S.)

According to (microelectronic device microwave / edited Heavenlove. - M.: Higher school, 1988. - S-75) multistage power splitters provide isolation output shoulders without the use of a valve device up to 30 dB in the frequency band with the ratio of the range of 1.44. Using modern ferrite valves (Ferrite microwave devices // Production Association "Granite", Rostov-on-don, 1992) isolation of the shoulders of the divider can be increased by at least 25... 30 dB at direct losses of about 0.5 to 0.8 dB.

As broadband amplifiers currently, the most widely used transistor amplifiers operating in the frequency range 0,1... 25 GHz and having a bandwidth gain 4... 80%, gain on cascade 5... 30 dB, noise figure of 2... 6 dB and the dynamic range of the input signal 80... 90 dB (Microa ectroni devices microwave / edited Heavenlove. - M.: Higher school, 1988. - p.78-86, 225).

All elements of the BU 6 also meet the criterion of industrial applications. The pulse shapers are easy to implement on the basis of, for example, the serial connection of the differentiating circuit, the amplifier-limiter and (if necessary) of the inverter.
