Fiber optic splice closure is suitable for protecting fiber cable splices in straight-through and branching applications.It can be placed in aerial,undergroud,wall-mounting and duct-mounting. Based on an advanced formula, the plastic parts are made of injection-molded, high-strength engineering plastic PC by numerical control equipment, therefore effectively prevent products from aging caused by coldness, heat, oxygen and ultraviolet radiation. The strong housing and main components provide fire resistant, waterproof, and quakeproof while protecting splices during pulling, torsioning and impacting.
