Fiber-optic coupling FOSC-400 Name FOSC is the synonym of the high quality of hermetic sealing, organizing of fibers, ease of use and flexibility of construction as the clutch FOSC 100, which was for the first time represented in 1986. Clutches FOSC were projected exclusively for fiber optics; they are not the modifications of clutches for the cables with the copper conductors and the difference they are obvious. To users FOSC is necessary the production of excellent quality, and they will obtain it.

Clutches FOSC 400 - the very new generation before the developing line of the articles, which are based beyond the ten-year experience of their use. They unite technical the equipment for the organization of the fibers of the clutches FOSC of 100[s] checked due to the new system of hermetic sealing. Hermetic sealing Base- cupola in FOSC 400 mechanical for simplicity of installation and remounting.

Hermetic sealing cables is characterized by the new thermoed-seat sleeve and thermo-melting by the [kleyushchey] system of the firms [Reykhem], which are established with the aid of the foehn. In order to simplify instruction, to decrease the number of component parts and to increase productivity before the line of articles they are used the general materials, which complete technologies.

Fiber-optic clutches FOSC 400 are produced three sizes: FOSC of 400 A, FOSC of 400 B, and FOSC of 400 D. all sizes are developed for the use with any construction of cable (free buffer tube, central basic tube, the free piling of fibers, tape), due to any conditions (air, suspension, underground padding, canalization, cable manholes) and for most varied types of connections (urgent, branch, splitting, repair).


All clutches FOSC 400 have hinged chutes, thanks to which simplifies access to any fiber of any chute without the undesirable actions beyond the remaining fibers. Furthermore, any fiber can be connected with any other fiber with the aid of the [mezhlotochnoy] connecting system. Technical flexibility and error-free access are important before the contemporary high-speed fiber networks.

Organization of the fibers Chutes for connection and piling the fibers before the clutches FOSC of 400A4, [V]2 and [V]4 can have two different holders of connectors. The universal holder of connectors is suitable for the welded and most common mechanical connectors. To 8 connectors can contain each chute of the type A and 12 connectors the chute of the type [V]. [Derzhatel] the connectors of high capacity it doubles the capacity of chute using 45 mm the protectors of welded joints (SMOUV-1120-02). Chutes for connection and piling the fibers in FOSC of 400D5 contain the interchangeable connecting modules.	Chute for the clutch of the type B
Before each “D” chute are established six connecting modules. Standard SM6 connecting module or “6- local” contains 6 single welded, mechanical or multi-fiber welded joints. There are also connecting modules for the multi-fiber mechanical connectors and the single welded joints of high density.
These connecting modules can be established also before the special chutes of the type v. to two connecting modules it can be established before one special chute Of [v]. [Eti]'s type special chutes of the type [v] they can easily be adapted subsequently for the fan-outs, the connectors, and so forth, because of the addition of new connecting [moduley].[Vse] of clutch FOSC 400 have hinged chutes, thanks to which there is a access to any fiber on any chute without the undesirable action beyond other fibers, beyond the reserve of buffer tubes, or introduction of losses. Furthermore, any fiber can be connected with any other fiber with the aid of the [mezhlotochnoy] connecting system. Technical flexibility and error-free access are important before today's developing high-speed fiber networks.	Special chute for the clutch of the type B with the connecting by the modules
