(without frequency conversion), and if necessary, any of them can be displayed using the output ports 13.1-13.4 for the subsequent connection of the output of a digital transmission system (DSPS)working speed transmission of binary signals up to 160 Gbit/s After switching the signals from each of the four channels with the spectrum of GSK-16 enter the corresponding port of the input splitter channels of the second layer 3, where using DMP second level 3.1₁-3.1₄each range of GSK-16 divided by 4 array of group channels GK-4/1...GK-4/4, and with appropriate frequency converters of the second level 3.2i-3.2i6 each of the spectra is the same spectra typical group of spectral channel HSC-4. The spectra of sixteen identical HSC-4 fall on the input switch of the channels of the third level 2, where freely interconnected (without frequency conversion), and if necessary, any of them can be displayed using the output ports 14.1-14.16 for the subsequent connection of the output of the DSP operating speed transmission of binary signals up to 40 Gbit/s After switching the signals from each of the sixteen channels with a range of HSC-4 enter the corresponding port of the input splitter channels of the first level 5, where with the help of SLE first level 5.1₁-5.1₄each SP is KTR HSC-4 is divided into 4 individual spectrum channels IR 1...IR-4, and with appropriate frequency converters of the first level 5.2₁-5.2₆₄spectra IR 1...IR-4 provides the model spectra of the main spectral channel USC. The spectra of the sixty-four of the same type OSK get to switch channels of the first level, where freely interconnected (without frequency conversion) and, if necessary, any of the 64 USC can be output using output ports 15.1-15.64 for the subsequent connection of the output of the DSP operating speed transmission of binary signals up to 10 Gbit/sspects frequencies of all 64 USC (with the addition of the symbol sequence numbers (RSC-1...USC-64) is the same and corresponds to the range of standard channel (on standard ITU-T G.692 with the spacing of the carrier frequencies in 100 GTZ) with an average frequency of, for example, 193,4 THz, which corresponds to a wavelength of 1550 nm.

The formation of the linear spectrum of the sixty-four spectra USC and one RSC-0 occurs in the reverse sequence (Fig). Signals with a spectrum of USC with outputs switch channels of the first level get on OK first level 7, where with the help of frequency converters of the first level 7.1₁-7.2₁₆spectra 64 of the same type OSK in groups of 4 USC converted to spectra of 4 individual channels (IR 1...IR-4), which with the help of 16 identical multiplexers of the first level 7.2₁-7.2₁₆GRU is Peroutka in sixteen spectra of the same type HSC-4. Then use the output switch channels of the second level of the same type HSC-4 can freely (without frequency conversion) to communicate, and if necessary, HSC-4 can be provided to connect to them via the ports of entry 17.1-17.64 DSPS speed transmission of binary signals is not higher than 40 Gbit/s, After switching sixteen HSC-4 group signal of each channel is fed to the input OK second level 9, where with the help of frequency converters 9.1₁-9.1₁₆the same spectra HSC-4 is converted to a diverse spectra of GC-4, using the multiplexer of the third level spectra are grouped into four similar GSK-16. Then use the output switch of the channels of the third level of the model HSC-16 freely (without frequency conversion) are interconnected and, if necessary, can be used to input signals from the DSP speed transmission of binary signals up to 160 Gbit/s in GSK-16 through input ports 18.1-18.64. After switching the four GSK-16 group signals from each of four GSK-16 arrives at the inputs OK third level 11, where with the help of frequency converters 11.1₁-11.1₄the same spectra GSK-16 is converted into diverse spectra of GC-16, which, together with the spectrum of the USC-0, the output of the multiplexer form a range linear channel group (a linear array of channels BFV), while the p on Fig.

The formation of the USC of the linear signal with 32 optical channels, shown in Fig is similar to that described above and shown in Fig.

The output of the linear signal of a single additional 65th RSC with zero room RSC-0 is made directly using the output port 28 located in the input SLE, and the input provided through the input port 29 located in the output of the MP. USC-0 is used for the reception (transmission) through different auxiliary signals (measuring, service, management, synchronization, and others)

If necessary, the range of frequencies of any of the 64 USC, through the installation of additional equipment, can be divided, in turn, on 4 more narrow standard spectral channel spacing of the carrier frequencies in the 25 GHz, compliant ITU-T G.694.

The choice of medium frequency USC-0, equal 193,4 THz (average wavelength equal to 1550 nm) due to the presence in most existing DSPS ports input/output with the same settings.

Selecting a fourfold hierarchy for promising group of spectral channels, HSC-4, GSK-16, GSK-64 is caused on one hand by the need to preserve the existing trends in the development of a fourfold hierarchy adopted for DSPS (STM-1, -4, -16, -64, -256, etc), and on the other hand the requirement for reduction of power losses in olnowich multiplexers, which increase dramatically with increasing number of channels in MP (DMP).

Introduction the frequency intervals between the spectra of GC-16 ISC due to the need to ensure parallel operation of the optical filters in the composition of input and output multiplexers of the third level.

Depending on the state of the linear tract of the FOTS-CF the claimed device can be used in the following modes:

- mode single-channel, when the signal transmission is carried out only on channel USC-0 with an average wavelength of 1550 nm, as shown in Fig;

- mode 32 optical channels when lbfv contains two shestnadesetkanalen group (GK-16/2 and GK-16/3) and service channel USC-0 (Fig);

- mode 64 optical channels when lbfv contains four shestnadesetkanalen group (GK-16/1 - GK-16/4) and service channel USC-0 (Fig).
