Description

Application:

HY-10-H-144A type of fiber closure is a fiber optic cable splice of multiple purposes, which can connect and protect cables. The fiber closures are capable of protecting fiber cable splices in straight-through and branching applications and shall be used in underground, aerial, wall-mounting, pedestal or direct buried, hand hole-mounting and duct-mounting applications. We always devote to the R&D of telecommunication equipment. Our fiber closures can greatly improve the performance of the operation of your network communication system. Closure is suitable for the applications up to 144 single fibers, which can cover most of the applications in the long-distance transmission and local fiber distribution networks, like Fiber To The Home / Fiber To The Curb (FTTH/FTTC). It is suitable for underground, aerial, pedestal or direct buried applications.
