FOSC-V03 5 ports Fiber Optic Splice Closures

Dome/Cap/Vertical/Butt type, 5 ports (4 round ports, 1 oval port), maximum support 96 bunch fibers.

General Details

In the Fiber Optic network, generally cables are limited to have 2km or 3km per reel, thus it requires a device to extending the fiber cable in the long haul cable network, CATV HFC network, FTTH PON network, etc. A traditional fiber optic splice closures with multiple ports for cable entry in and with ports for cable extending, distributing, branching, etc. inside the box body, there is space with fiber optic splice tray installed for holding, protecting and managing the fiber cable after cable been spliced. There are inline type, some times we say horizontal type fiber optic splice closures, and dome type or vertical type, butt type. However, recently closures are with more function than cable protection and joint, but splitting, thus splitting type fiber optic splice closure is very popular now, all this joint closures are made of high strength plastic, with excellent waterproof, dust proof, features. Tarluz offered various of FOSC, please feel free to contact for more product information.
