FOSC A16 Fiber Optic Splice Closure

Application

FOSC A16 Fiber Optic Splice Closure is designed for large amount of fiber optic cable distribution. It is mainly used in distribution sector of FTTH networks. According to project solution FOSC A8 Fiber Optic Splice Closure can be used in aerial laying: on support or on line, in the ground, in cable canalization, on buildings’ walls, for assembling in special cabinets.

Benefits

Closure is produced in dome shape and has 17 cable ports, allowing using it as splitting or dead-ending device.

A closure’s base is made of high-strength plastic. Closure’s design has possibility of easy multiple accesses to cassettes; it is compatible with any types of fiber optic cables (one/two jackets, one/two strength elements, armoured and so on) and is also suitable for transit fiber laying.

Sealing of cables input is made by means of shrinkable non-armoured material with glue sublayer. The closure’s design allows fixing of the main strength element and peripheral strength elements of joined optic cables.

If armoured cables are input into the closure, it is possible to earth armoured cables via earthing pin and individual end earthing conductors (are included into the delivering set according to the order).

The closure has universal plastic tray to assemble up to 4 cassettes with 12 fibers each. The total amount of plastic trays is 6 units. If there is a necessity of optic terminated splitters assembling, an additional option for 24 SC connectors/adapters is possible. The closure’s base has an optional flash test valve.
