Rapid Development Of Indoor Fiber Optic Splice Closure Cable

Date:28-03-2019

With the fast development of Fiber Optic Splice Closure communication technology and the trend of FTTX, indoor fiber optic cables are more and more required to be installed between and inside buildings. Typical indoor fiber optic cable types include GJFJV, GJFJZY, GJFJBV, GJFJBZY, GJFDBV and GJFDBZY. Compared with outdoor use fiber cable, indoor fiber optic cable experience less temperature and mechanical stress, but they have to be fire retardant, emit a low level of smoke in case of burning. And indoor fiber cables allow a small bend radius to make them be amendable to vertical installation and handle easily.

Most indoor fiber optic cables are tight buffer design, usually they consist of the following components inside the cable, the FRP which is non-metallic strengthen member, the tight buffer optical fiber, the Kevlar which is used to further strength the cable structure, making it resist high tension, and the cable outer jacket. The trend is to use LSZH or other RoHS compliant PVC materials to make the cable jacket; this will help protect the environment and the health of the end users. Usually the single mode indoor fiber optic cables are installed between the buildings where the distance is more than 100 meters, while multimode indoor fiber optic cables are used shorter distance connections. We supply SMF and MMF indoor fiber cables with various structures for different applications.

Fiber optic fusion and mechanical splices are placed in mechanical closures that are referred to as "splice enclosures", "splicing trays" or "splicing organizers".  Fiber optic splice trays are designed to provide a location to store and to protect the fiber cables and the splices. Fiber optic splice trays are located at intermediate points along a route where cables are required to be joined or at the termination and patch panel points at the end of fiber cable runs.
