The technical field.

This invention relates to optoelectronic systems, subsystems, components and, in particular, to components with narrow tolerances, used to align the optical fibers in the implementation of the connection of single optical fibers or bundles of optical fibers.

The level of technology.

Channels of fiber-optic communication is a system that is often chosen and used in protection systems, as well as in industry and Commerce because of their high efficiency and small size. The advantages of using fiber optics, in particular, occur when applications relating to large distances, for example applications in the communication lines between cities and between continents, due to the lower cost of components for converting electrical signals to optical and back to electric E-O-E, fiber rape the development and fiber-optic cables in comparison with purely electrical systems, using coaxial copper cable, which does not require E-O-E conversion. Such fiber optic telecommunication system may contain hundreds of miles of fiber between terminals.

Systems designed for smaller distances, usually contain only a few tens of kilometers of fiber between terminals and systems designed for ultra-small distances, contain only a few tens of meters of fiber between terminals. Although fiber-optic communication lines for telecommunications and data transmission in the metro, public places and homes are short compared with the lines of telecommunication, a lot of them. The number of components required for the fiber used in this way, great. In such systems, designed for use over short distances, fiber optics largely depends on the value of E-Oh-E devices (terminals) conversion and layout support schemes, as well as the cost of any passive and active optoelectronic devices and equipment connected between the ends of the terminal. Therefore, to increase the use of active and passive optoelectronic systems, subsystems and components for small and ultrasmall (VSR) distances, their average sales price should be reduced is. The decrease in average sales prices will help to stimulate the use of what is needed to justify investment in high-technology production.

An important element influencing the price of both active and passive fiber optic components and United with them cable is the connector in a mating itself. Cuff and associated devices for their combination (for example, a detachable coupling for the connection of single optical fibers, grounded pins for connection set (bundle) of optical fibers) are the main contributors to the creation of the rates currently used fiber optic connectors. Leveling (combining) components are typically required to align the optical fibers with active and passive devices, as well as for combining two optical fibers with the aim of creating a permanent connection and joining (splicing). Precision alignment of two polished end of the fiber is necessary in order to have confidence in the fact that the total optical loss in the junction of the fiber is equal to or less than the target loss optical connector system. For single-mode telecommunication fiber is usually correlated with the tolerances on the alignment (alignment) of the fiber optic connector, which is less than 1000 nm. Connectors, the use of which has been created for the connection as a parallel, and a single optical fibers, working with multi-Gigabit speeds, must be connected to subsystems (subcomponents), fabricated with sub-micron accuracy. The production of parts with such accuracy levels seemed promising enough. Therefore, to ensure that the final product was economically beneficial, it must be made fully automatic, very high-speed method.

The basic design of modern connectors has not changed for more than 20 years. The basic design of the cuffs, detachable couplings and gutters are to 1970 years. Traditional cuffs are hard cylinders, provided with a hole located on the center axis of the cylinder, in which position the fiber, typically with a diameter of 0.125 mm, and fix it there. The external diameter of the cylinder, as a rule, is 2.5 mm, and its length, as a rule, 10 mm For the most part, the goods on offer at the present time, have the same design, but made from different materials and in different ways. When used to connect a single optical fibers cuffs are usually made of machined metal blanks or Diocleziano ceramics. During multi-stage procurement process Zirconia molded to give them the approximate size,and then the workpiece is mechanically treated and polished to obtain a desired size and tolerances. For the connection of a bundle of optical fibers cuffs are usually made of a thermosetting plastic, impregnated with silicon beads. Using silicon beads leads to the fact that the coefficient of thermal expansion of the composite material plastic-glass is closer to the coefficient of thermal expansion of quartz fibers than the coefficient of thermal expansion of pure plastic. It is generally acknowledged that traditional fiber connectors too expensive to produce. If the fiber is chosen as a means of communication in small and super small distances, the cost of production of fiber-optic connectors must be reduced.

The stamping processes widely used in the processes of mass production of cheap serial parts. Stamping is a production method in which the workpiece (a workpiece)such as a metal strip, squeeze between the components of the stamp to give it a predetermined shape or pattern. Components of the stamp may perform various operations on the workpiece, such as cutting, shaping (for example, punching, pulling, bending, Frantsevna and flexion of the slice) and forging (e.g., chasing). Usually forming belongs to the stamping operation, in which the thickness of the workpiece does not change significantly, t is the time as forging refers to the operation of stamping, when the thickness of the workpiece varies significantly. Compared to machining processes molded blanks Zirconia or molded thermosetting plastic impregnated quartz beads, stamping process is relatively quick.

But still the stamping processes were not effective in the production of parts with tolerances that are acceptable for optoelectronic components. U.S. patent No. 4,458,985 name Balliet and other dedicated connector for the fiber. Balliet briefly indicates that some components of the connector can be made by way of minting (forging or stamping (for example, column 3, lines 20-21, 55-57). However, Balliet does not amplify such methods of stamping, not to mention the expanded description of the method of stamping to produce parts with tolerances in the range 1000 nm.

In the examination of the application on invention USA (number not yet available) called "Stamping system for producing parts with high tolerance" ("Stamping System for Manufacturing High Tolerance Parts"), filed July 15, 2003 in the name of our company included in this invention in its entirety by reference, we describe the system and method of stamping parts, such as optoelectronic systems, subsystems and components with tolerances of less than 1000 nm. Figure 1 represents schematic the prioritization of the image, illustrating a system 10 for forming optoelectronic components with tolerances of less than 1000 nm. Stamping system 10 includes, in particular, stamping press 20, one or a sequence of stamping blocks 25 and interaction system 35. Each stamping unit 25 may include tools such as a punch and die, for performing a specific operation of the stamping on the workpiece, the sensors for measuring the flow and/or condition of tools and other equipment, such as welding machine. Stamping blocks 25 have a new design for the direction of the punch, with significant (tolerance) align (alignment) with the matrix. Stamping blocks 25 are also specially designed to minimize the number of moving components contained in the support structure in the direction of the punch to the die. Stamping press 20 actuates the sequence stamping blocks 25. Transmission system 35 facilitates the transfer of power press 20 on the plug, and the press 20 is structurally separated from the punch. Transmission system 35 also allows you to isolate each stamping unit, in the sense that operations on one unit does not affect the operation on another block.

The method precision of the personnel is pawky allows to produce parts with "six Sigma" ("six sigma") geometric field tolerance to 1000 nm. Statistically this means that a maximum of 3.4 parts per million will not be required to comply with compliance sizes given 1000 nm field tolerance. In the case of the normal distribution, to satisfy the conditions of the six Sigma process, the standard deviation of the full process (cycle) must be less than or equal to 83 nm [(1000 nm/2)/6=83 nm], provided that on average, the process remains constant. In practice, you should make a deviation tolerance of the process average. For the case when it is assumed that the process variation is on average ±1.5*sigma, the maximum standard deviation is reduced to 67 nm [(1000 nm/2)/7.5=67 nm]. And again, under normal statistics, in order to achieve multi-stage process with n precision stages, each of the n stages must satisfy the condition sigma/n^0.5 in. Thus, in this example, if n = 4, then σ (at each stage) must be less than or equal to 33 nm.

It is therefore desirable to have a precision optoelectronic systems, subsystems and components, the design of which allows to produce high-performance way of stamping, giving the ability to produce parts with tolerances within 1000 nanometers. It is also desirable to have a precision optoelectronic systems, subsystems and components, the design of which allows proizvoditeli using stamping system, described in the pending application on the invention of U.S. No.[not yet available], filed on our name.

Fully semi-circular half cuff

Figure 2 is a three-dimensional image of an optoelectronic system 100 according to one embodiment of the present invention. Figure 3 is a three-dimensional image of an optoelectronic system 100 shown in figure 2, simple is antonym separation of the parts. Optoelectronic system 100 includes an optical fiber 110 and 120, a pair of identical precision seals 130 and 140, as well as precision split sleeve 150. Fiber 110 and 120 may be optical fibers of any type well known in the prior art, such as single-mode or multimode fiber. Fiber 110 and 120, depending on specific requirements, also can have any outer diameter, for example 0.125 mm

Cuff 130 and 140 is rigidly fixed to the ends of the optical fibers 110 and 120, respectively, to improve combining (joining) of optical fibers 110 and 120 to each other. 4 and 5 represent the image of the front and rear cuffs holding the optical fiber, such as cuff 140 holding the optical fiber 120, shown in Figure 3. The sleeve 140 is in General hard case 145, generally uniformly cylindrical shape with a length L, the front and rear surfaces 160 and 170 and arcovio/contact the outer surface 180. The sleeve 140 also includes trunk/channel 190 passing through the housing 145 cuffs along its entire length L. the Channel 190 is of such a size and shape to closely fit the outer diameter of the optical fiber 120. The optical fiber 120 is placed (in the nest) in the channel 190 so that the end 200 of the optical fiber 120 is almost coplanar and aligned with the front surface of the cuff 160 140 (as shown in Figure 5). The front surface 160 is practically the flat. The plane of the front surface 160 may be oriented at a fixed angle relative to the longitudinal axis of the channel 190. This enables you to better make the connection of fiber-fiber and reduces accordingly the reverse optical reflections in the optical fiber. But experts it is clear that alternative, the front surface may not be flat (not shown).

6 is a three-dimensional image of the cuff 140 and the optical fiber 120, shown in Figure 4 and 5, with a spatial separation of the parts. Case 145 cuff contains two identical halves 210 and 220 cuff. Fig.7 is a perspective view of half of the cuff, such as half of the cuff 220, shown in Fig.6. Half cuff 220 is fully semicircular end section and a flat surface 230. Two halves 210 and 220 cuffs together on their flat surfaces 230. On a flat surface 230 is made trough 240, passing along the entire length of the half of the cuff 220 to accommodate the end 200 of the optical fiber 120. The groove 240 has a constant shape throughout its length. The trench 240 may be semi-circular (as shown in Fig.7), V-neck (not shown) or any other gutter configuration, can accommodate (as in female) outer diameter of the fiber. When the two halves of the cuff together chute 240 two halves 210 and 220 cuff set the channel 190 is aniety 140. Alternatively, the groove may have a shape that is not constant along the entire length. For example, the groove may be so shaped that when connected together half cuff troughs define a channel having an end tapered shape. This makes it easier to place the fiber in the channel and record it in the cuff.

Half cuff 220 contains recesses (grooves) 250 applied along the edges of the flat surface 230, which helps to bring together the halves 210 and 220 cuff. Half cuff 220 may contain grooves 250 on both side edges 232 and 233 along the length of the flat surface 230 (as shown in Fig.7), or any of the side edges 232 and 233 (not shown), or any one of, or both of the rear edges 234 and 235 (not shown). The recess 250 may pass substantially through the entire length of the half of the cuff 220 (as shown in Fig.7) or to pass only part of the length of half of the cuff (not shown). Fig is a rear view of the cuff 140, shown in figure 5. When the two halves 210 and 220 cuffs gather together on their flat surfaces 230, the notches 250 halves 210 and 220 cuff set grooves 260 on the arcuate outer surface 180 of the cuff 140. As will be further shown below, half 210 and 220 cuffs together along the grooves 260. For example, half 210 and 220 cuff can be welded together along the groove 260. The slots 260 are of sufficient depth that the weld was materialistically inside grooves 260 and advocated arcobasso outer surface 180, that could affect the alignment (alignment) of the optical fiber 120. Alternatively, to connect together the halves 210 and 220 cuff can be used adhesive material.

In the embodiment shown in Figure 4 and 5, the dimensions of the cuff 140 can be: diameter end section is 2.5 mm or 1.25 mm and a length of 10 mm, it is Clear, however, that these dimensions are given only as examples, and may be used for other sizes.

Returning to Figure 3, it should be noted that the optoelectronic system 100 includes a detachable coupling 150. On Figa shows a cross-section detachable coupling 150, made by the line 9-9 shown in Figure 3. The split sleeve 150 has a substantially hollow cylindrical shape, a length of 1, the inner diameter d which is slightly less than the external diameter of the collars 130 and 140, and the inner surface 265. For example, if the external diameter of the cuff is approximately 2.499±0.0005 mm, the split sleeve 150 may have an internal diameter d, which is about 2.493+0.004-0.000 mm Detachable coupling 150 is provided with a slit 270, which runs along its entire length 1. The slit 270 allows you to increase the inner diameter d of the split coupling 150 in order to accommodate the cuff 130 and 140 of larger diameter.

The split sleeve 150 facilitates alignment (alignment) all 200 of optical fibers 110 and 120 relative to each other. Cuff 130 and 140 that holds the COO is responsible fiber 110 and 120, placed (inserted) through the opposite ends 280 and 290 detachable coupling 150. Inner diameter d of the split coupling 150 is slightly increased due to the slot 270 in order to accommodate the larger outer diameter of the collars 130 and 140. When the cuff 130 and 140 placed inside detachable coupling 150, the split sleeve 150 is linked to the arcuate outer surface 180 of the collars 130 and 140. When the movement of the collars 130 and 140 in direction to each other the inner surface 265 of the detachable coupling 150 sends cuff 130 and 140 relative to each other up until the ends of the optical fibers 110 and 120 will not come into contact with each other. When the cuff 130 and 140 are aligned with each other in a detachable coupling 150, the ends 200 of the optical fibers 110 and 120 also precision are adjacent to each other, resulting in the alignment of optical fibers 110 and 120.

The configuration of the seals 130 and 140 and detachable coupling 150 allows you to produce and assemble these components using the method of stamping, giving the ability to produce parts with tolerances of less than 1000 nm. Can be used a method of forming described in the patent application U.S. under consideration [the room is not yet available], filed on our name.

Cuff 130 and 140 can be made in various ways, for example by way of forging. Figure 10 is a structure "strip geometry, which is carried out at about the stage well for forging cuff 140, shown in Figure 4 and 5. The sequence includes, for example, nine stamping blocks S1-S9. As shown by device strip geometry, the two halves 210 and 220 of the cuff can be made from the same tape source material at one time carried out in a single stage configuration, such as in blocks S1-S4. The front and rear surfaces 160 and 170, and the arcuate outer surface 180 is forged into these blocks. In another block, such as block S5, the flat surfaces 230 halves 210 and 220 cuff forging a trench 240. Half 210 and 220 cuffs are also provided with notches 250 for connecting together the two halves. Two halves 210 and 220 cuffs bring together and align with the fiber in blocks S6-S8 in preparation for laser welding in block S9. Half 210 and 220 cuff can also cook without fiber. In this case, the optical fiber is inserted later. Laser welding machine Starweld 20 production Rofin, Inc. is an example of a laser welding apparatus in which the laser pulse is directed to the welded piece. In addition to welding, the laser system can be used to remove the coating from the optical fiber, as well as for proper preparation of the end surface of the fiber. When the two halves 210 and 220 cuffs are welded together along the slots 260, cuff 140 is securely and precision horse holds the fiber.

The split sleeve 150 may be manufactured by a method of moulding. The split sleeve 150 may be sequentially formed, including four cutting block and five to six blocks forming. On Fig.9b-e shows the cross section of the split coupling 150, showing, as of the workpiece 152 was obtained detachable clutch in the final configuration. As shown in Fig.9b, forming a detachable coupling start with one flat workpiece 152. Then a flat workpiece 152 is subjected to sequential molding for molding blocks (as shown in Fig.9b-9d) with a detachable clutch in the final configuration shown in Figa.

Cuff 130 and 140 and the split sleeve 150 is designed to be compatible with traditional cuffs used in the art at the present time. As mentioned above, traditional cuffs are cylindrical in shape and have a circular end section. Cuff 130 and 140 have a round end section, which contributes to the alignment of optical fibers held cuffs 130 and 140, with the optical fibers held traditional cuff. Detachable coupling 150 is adapted to accommodate the cuffs, which has a cylindrical shape, such as a traditional cuff. It is clear that the cuff 130 and 140 can be designed to not have the ability to compatibility. For there is, cuff 130 and 140 and the coupling 150 can have other end section, such as square or rectangular (not shown).

Partially semicircular half cuff

In an embodiment, shown in Fig.7, half cuff 220 is fully semicircular end section. Can be developed half cuff other forms, such as partially semicircular end section. 11 is a three-dimensional image of an optoelectronic system 400 according to another variant implementation of the present invention. On Fig shows the three-dimensional image optoelectronic system 400, shown at 11, with a spatial separation of the parts. Optoelectronic system 400 includes an optical fiber 410 and 420, a pair of cuffs 430 and 440, and a detachable coupling 450.

Each of the cuffs 430 and 440 includes a housing 442, generally uniformly cylindrical shape with a length L, the front and rear surfaces 470 and 475, Arcoveggio/contact the outer surface 480 and trunk/channel 490, passing through the body 442 along its entire length L. In Fig shows a view from the end showing the front surface 470 cuff 440, shown in Fig. Channel 490 is of such size and shape in order to accommodate, for example, the outer diameter of the optical fiber 420.

Case 442 cuff contains two identical halves 510 and 520 of the cuff together. Pig is a three-dimensional image is their half of the cuff, such as half cuff 520 shown in Fig. Half cuff 520 is partially semicircular end section, half cuff 520 has a flat surface 530 and 535 and Arcoveggio outer surface 536 and 537. Two halves 510 and 520 cuffs gather together on their flat surfaces 530. On a flat surface 530 performs the groove 540, running the length of the half 520 cuff for placement (as in female) fiber 420. The trench 540 has the same shape along its entire length. When the two halves 510 and 520 cuffs together gutters 540 two halves 510 and 520 cuff set the channel 490 cuff 440. Alternatively, the groove may be in the form, not the same along the entire length. For example, the groove may be so shaped that when connected together half cuff troughs define a channel having an end tapered shape. This makes it easier to insert the fiber into the channel and record it in the cuff.

Half cuff 520 provided with grooves 550 located along the edges of the flat surface 530 that helps to bring together two halves 510 and 520 cuff. Half cuff 520 may contain notches 550 on both side edges 531 and 532 along the length of the flat surface 530 (as shown in Fig), or any of the side edges 531 and 532 flat surface (not shown), or any one of, or both of the rear side edges 533 and 534 (not shown). The notches 550 m which may be substantially the entire length of the half cuff 520 (as shown in Fig) or to pass only part of the length of half of the cuff (not shown). When the two halves 510 and 520 cuffs together on their flat surfaces 530, the notches 550 halves 510 and 520 cuff set grooves 560 on arkovich outer surfaces 480 cuff 440.

In an embodiment shown in Fig, sizes cuffs 430 and 440 can be: diameter end section is 2.5 mm or 1.25 mm and a length of 10 mm, it is Clear, however, that these dimensions are given only as examples, and may be used for other sizes.

Optoelectronic system 400 includes a detachable coupling 450 having an inner diameter that is slightly smaller than the outer diameter of the collars 430 and 440, the inner surface 565 and 570 slit, allowing to increase the inner diameter of the split coupling 450 order to accommodate the cuffs 430 and 440, which has a larger diameter.

Detachable coupler 450 promotes alignment (alignment) of the ends of the optical fibers 410 and 420 relative to each other. When the cuff 430 and 440 are placed inside detachable coupling 450, detachable coupler 450 is fixed on arkonides outer surface 480 cuffs 430 and 440. As shown in figure 11, the sleeve 430 and 440 are not completely fill the inner diameter of the split coupling 450. However Arcoveggio outer surface 480 cuffs 430 and 440 retain contact with the inner surface 565 detachable coupling 450 for the direction and alignment of the optical fibers 410 and 420 each other. Compared with a sleeve having a cylindrical F. the RMU, partially semicircular design halves 510 and 520 cuff allows less close contact seals 430 and 440 with the inner surface 565 detachable coupling 450. Therefore, the effect of any not odnorodnosti on the inner surface 565 detachable coupling 450 in the direction cuffs 430 and 440 are minimized.

Compared with traditional cuffs having a uniform cylindrical shape, the use of partially-circular halves 510 and 520 cuff causes for the manufacture of each part requires less material. If so, then the manufacturer cuffs 430 and 440 would be more economical from the standpoint of material cost. In addition, partially semicircular design with proper layout and line split sleeve of appropriate design has the advantage in relation to the density of a bundle of optical fibers, tightly Packed in one - or two-dimensional array. On Fig shows rear view of a Packed array 600 cuffs. The array 600 cuffs includes, for example, three cuff 610, 620 and 630. Cuff 610, 620 and 630 respectively hold the optical fiber 612, 622 and 632. Flat surface 535 allows tight packaging of the cuff 610,620 and 630 and accordingly the optical fiber 612, 622 and 632. Detachable coupler 640 is of such size and shape to fit tightly Packed cuff 610, 620 and 630.

Moreover, the design and the cuffs I 430 and 440 allows the manufacture of these components by way of forging. On Fig the design of "the strip geometry, carried out in one stage for forging cuff 440, shown in Fig. The sequence includes, for example, nine stamping blocks S1-S9. As shown in the example of the strip circuit, the two parts 510 and 520 of the cuff can be made from the same tape source material for one stage ("two-up"), for example in blocks S1-S4. The front and rear surfaces 470 and 475, and the arcuate outer surface 480 is forged into these blocks. In another block, such as block S5, the flat surfaces 530 halves 510 and 520 cuff forging a trench 540. Half 510 and 520 cuff is also provided with the slots 550 for connecting together the halves 510 and 520. Two halves 510 and 520 cuffs bring together and align with the fiber in blocks S6-S8 in preparation for laser welding in block S9. Half 510 and 520 cuff can also cook without fiber. In this case, the optical fiber is inserted later. When the two halves 510 and 520 cuffs are welded together along the slots 560, cuff 440 reliable and precision determines the location of the end of fiber.

Cuff 430 and 440 and detachable coupler 450 is designed to be compatible with traditional cuffs used in the art at the present time. As mentioned above, traditional cuffs are cylindrical inform and have a round end section. Cuff 430 and 440 have a partially circular end section, which contributes to the alignment of optical fibers held cuffs 430 and 440, with the optical fibers held traditional cuff. Detachable coupler 450 is adapted to accommodate barrel cuffs, such as traditional cuff. It is clear that the cuff 430 and 440 can be designed in such a way as to not have the ability to compatibility. In principle, the sleeve 430 and 440, as well as the sleeve 450 may have the other end section, such as square or rectangular (not shown).

Multi-strand cuff

Embodiments of the cuff shown in Figure 4 and 12, designed to align (alignment) of single optical fibers. Cuffs can be designed to hold and align the set (bundle) of optical fibers. Pig is a three-dimensional image stranded optoelectronic system 700 according to another variant implementation of the present invention. For example, optoelectronic system 700 holds and aligns the two fiber 710 and 712 relative to the optical fibers 720 and 722. However, optoelectronic system 700 may be designed to hold any number of optical fibers. Optoelectronic system 700 includes a detachable coupler 750. On Fig shows a three-dimensional image of an optoelectronic system 700 without connector is Noah clutch 750. Optoelectronic system 700 comprises a pair of cuffs 730 and 740. Cuff 730 and 740 firmly hold the ends of the optical fibers 710, 712, 720, and 722, respectively, which contributes to the alignment of optical fibers with each other.

On Fig shows a three-dimensional image of a pair of sleeves, such as sleeve 730. The sleeve 730 is capable of holding two fiber 710 and 712. Cuff 730 includes a housing 732, generally uniformly cylindrical shape having a front surface 760 and two channel 790 and 792, having such a size and shape to closely fit the outer diameter of the optical fibers 710 and 712.

On Fig shows a three-dimensional image of the cuff 730 and optical fibers 710 and 712 shown in Fig, with a spatial separation of the parts. Case cuff 732 includes two identical half 810 and 820 cuff. Pig is a three-dimensional image half of the cuff, such as half 820 cuff shown in Fig. Half 820 cuff has a flat surface 830. On a flat surface 830 is made trough 840 and 845 to accommodate (as in female) ends of the optical fibers 710 and 712. Gutters 840 and 845 have a constant shape along the entire length. When the two halves 810 and 820 cuffs together gutters 840 and 845 of the two halves 810 and 820 cuff set channels 790 and 792 cuff 730. Alternatively, the trench may have a form that is not constant along the entire length. For example, the trench may be so shaped that when soy is ininii together half cuff gutters set channels, with the end of the conical shape. This makes it easier to put (paste) the fiber in the channel and record it in the cuff.

Half 820 cuff provided with grooves 850, applied along the edges of the flat surface 830, which helps to bring together two halves 810 and 820 cuff. When the two halves 810 and 820 cuffs gather together on their flat surfaces 830, excavation 850 halves 810 and 820 cuff set grooves 860 (shown in Fig) on the surfaces of the cuff 730. As will be further shown below, half of the 810 and 820 cuff can be connected together along the grooves 860. For example, half of the 810 and 820 cuff can be welded together along the groove 860. Grooves 860 have sufficient depth so that the weld material remained inside the grooves 860 and will not extend beyond the surface of the cuff 730.

Optoelectronic system 700 may include guide pins 755 for alignment (align) cuffs 730 and 740, and accordingly the optical fibers with each other. Half 820 cuff contains gutters 870 performed on a flat surface 830, for placement (in the nest) guide pins 755. When half of the 810 and 820 cuffs together gutters 870 set the channels or holes 875 for guide pins. Channels 875 for the pins are of such a size to exactly fit the guide pins 755. Guide pins 755 tightly inserted into the channels 875 for pins cuff 730, so is the guide pins 755 protruding beyond the front surface 760 cuff 730. Part of the guide pins 755, projecting beyond the front surface 760 cuff 730 includes channels 875 for pins cuff 740. Guide pins 755 guide and align the cuff 730 relative to the cuff 740, thus guiding and aligning (combining) fiber 710 and 712 with optical fibers 720 and 722.

Channels 875 for pins and guide pins 755 attach cuffs 730 and 740 ability to compatibility with traditional stranded cuffs used in the art. Professionals it is clear that the cuff 730 and 740 can be developed without channels 875 for pins and guide pins 755.

Alternatively, the optoelectronic system 700 may include a detachable coupling 750 to facilitate alignment of the ends of the optical fibers 710 and 712 with the ends of the optical fibers 720 and 722. In another alternative embodiment, the cuff may include a gutter for alignment, to facilitate alignment of the optical fibers. Pig is a three-dimensional image of an optoelectronic system 900 according to another variant implementation of the present invention. On Fig shows a three-dimensional image of an optoelectronic system 900 shown in Fig, with a spatial separation of the parts. Optoelectronic system 900 includes a detachable coupler 910 and a pair of stranded seals 920 and 930, retaining many patterns (beams) 914 and 915 of the optical fibers. aniety 920 and 930 have a pair of identical halves 940 and 950 cuff, United together. The alignment trough 960 performed on the outer surface 970 halves 940 and 950 cuff. The alignment trough 960 may be V-shaped or can have another shape. Gutters 960 may be performed, for example, by way of forging. Detachable coupler 910 contains complementary protrusions 990 having a size and shape that allows them to enter into the gutters 960 cuffs 920 and 930. For cuffs 920 and 930, equipped with a V-shaped grooves, protrusions 990 is made V-shaped, to coincide with V-shaped grooves 960. When the cuff 920 and 930 is inserted into the split sleeve 910, the protrusions 990 are in the gutter 960. The protrusions 990 sent a pair of cuffs 920 and 930, and thus combine with each other tracts (bundles) 914 and 915 of the optical fibers. Use alignment grooves 960 cuffs 920 and 930 and the corresponding protrusions 990 detachable coupling 910 removes the necessity of using guide pins. This means that the cuff can be smaller in dimensions, and its production will require less material.

Design multi-strand cuff shown in Fig and 23, allows to make the cuff a way of forging. In the pending application on invention USA [serial number not yet available], filed on our name, was described by a punch (not shown) for making a multi-strand cuff. Using a punch, you can forge trench 840 and 845 to accommodate the op is Belokon and gutters to accommodate them (as in female) guide pins.

However, the protrusions 1020,1025 and 1030 cuff 1000 maintain contact with the inner surface of the split coupling 1060 direction of the pair of cuffs 1000 and accordingly the optical fibers relative to each other. Compared with a sleeve having a cylindrical shape, design star cuff 1000 allows less contact with the inner surface of the detachable coupling 450. Therefore, the effect of any defects on the inner surface of the detachable coupling on direction (alignment) cuffs 1000 minimized. In addition, the design of the star-shaped cuff 1000 is that for the manufacture of each cuff less material is needed. This means that as a result of satr what you're on material for the manufacture of cuffs 1000 will be reduced.

SUBSTANCE: invention concerns fibre optics and optronics. It can be applied to linking of groups of fiber-optical cables among themselves. In the socket the centralisers are executed from an elastic material. One of edges of a gash of every centraliser is fixed in a socket material. On other edge from each leg of a tip there are salients. From each leg of the fiber-optical socket the slider is available. There are holdfasts of an open standing of the socket. At centre of each of the socket legs, there are the buttons relieving a holdfast. Each fiber-optical plug has the mobile lattice of squeezing of springs or an elastic material for plug tips springing. In each plug there is a lever. There is a device of fixing of a lattice. Vacuities of the centralisers densely sweep plug tips. Thus moves a slider, fixing a plug in the socket and voiding the mobile lattice for travel. The elastic material creates necessary effort of squeezing of end faces of tips.

EFFECT: simplification of linking and socket release, the small sizes of a socket at linking of major number of fibrils, pinch of accuracy of alignment and making of necessary clamping effort of end faces of fibrils on each pair of joined light guides, possibility of installation of optical fibrils in fiber-optical plugs in field requirements that allows to refuse application in fiber-optical networks of patch-panels.
