It is intended for connecting the cables for the sake of the small number of fibers and for the branch connections. Branch connections - those, where the majority of fibers before the cable is " passed after transit” through the clutch and only several fibers are isolated from the cable and will be given beside the building or beside the optical net module (ОСМ).

Clutches FOSC 400 B2 and FOSC 400 B4 are identical with exception of the configurations of terminal cable ports. Additionally to the large oval port for the basic distribution cable, clutch B2 has two large round ports for the branch cable connections, and clutch B4 has four small round ports for the numerous offshoots.

Clutch is developed for the use with any conditions of the padding of fiber-optic cable (air, on the support, before ground, before the conduit run or the cable manholes) and is applicable for the diverse variants of the inosculation of cable (straight, splitting, repair, transit configurations).

Passage clutch FOSC-500AA ensures the overall protection of cables from the environmental effect and is intended for the use on the cables, which are hung up, lay before the conduit run or directly beside ground. FOSC-500B the family of the optical clutches, utilized with the installation of the cables of external application.

Blind metallic clutch, specially developed for the use with the [optovolokonnym] cable, mounted on the airlines of power transmission. Clutch is developed for the overground use. It can be used for hermetically sealing of branch and splitting adhesions, common points, distributive sections of network.

Blind metallic clutch, specially developed for the use with the [optovolokonnym] cable, mounted on the airlines of power transmission. Clutch is developed for the overground use; it can be fixed during the high-voltage supports, the posts, the walls or other constructions.
