Description:

Fiber optic closure is a passive component which can provide a great protection for fiber splicing point. Aerially assembling, pipeline assembling or buried underground are all available. Generally, closures have two types to face different situations: Cap (Vertical) Type and Half (Horizontal) type. The Cap type closure is also called Vertical closure. The input and output ports are at the bottom of the closure.

This closure type is more suitable for the application on accessing layer. The Half type closure is also called Horizontal closure. The input and output are on the both sides. This closure is more suitable for backbone application.

Tongda provides various shapes closure of both type. All the closures we offered are fully mechanical sealing structure which ensure a great sealing performance. High quality ABS material also ensure the durability no matter the closure is in air, in pipeline or buried underground.
Fiber Optic Splice Closure:

A fiber optic splice closure is only for protecting interconnection of fibers. It does not combine the ability of optical splitting. Generally, the splicing tray offered as accessories has two types: single side 12 cores type and double sides 24 cores.
