Product Description


Optic FIBER clousure dome type is applied in the junction and protecting of the fiber.It can be place with the aerial cable or buried in earth or put in the pipeline.The outer part and the fusing part of the clousure are made of the project plastic with the virtue .
Fiber optic splice closure is a Fiber Infrastructure System Technology. It is the environmentally sealed enclosure for the fiber management system that provides the functions of splice and passive component integration in the external network. Single-ended design. Base and dome are sealed with a clamp and O-ring system, 16 round entry/exit ports for drop cables and 1 oval port for looped cable.

The scope of application is: aerial, underground, wall-mounting, duct-mounting and handhole- mounting. The ambient temperature ranges from –40℃ to +65.

The closure adopts heat shrink sealing structure. There is one oval shaped cable port entrances in base.
The big entrance is used for the sealing of uncut straight-through fiber cable, the small ports are used for branch fiber cable and drop cable.
To adopt engineering PC plastic with high-strength to make the closure has longer life time and excellent sealing performance.
It could save the installation time and improve work efficiently.
