dome closure(FOSC 400B4/GJS03B)

The dome fiber closure(FOSC)can be installed in aerial locations, ducted applications, direct buried, manholes.

The dome optic fiber closure (fiber enclosures)are widely apply for the connecting of optical cable. 1. The material of FOSC body:ageing resistance & ultraviolet radiation resistance2. Base-to-dome seals on FOSC are mechanical and heat-shrinkable for ease of installation and reentry. 3. Compatible with most cable types(single fiber or ribbon), and cable constructions(loose tube, central core, slotted core, modular). And the product can be used in any environment (aerial, buried, handhole, manhole)and in many applications(tap-off, expressed, branch, and repair)4. No special tools are needed to open the closure, and it can be opened and used repeatedly.
