Erect Fiber Optic Splice Closure
Fiber Optic Splice Closure, Fiber Optic Closure, Fiber Optic Joint Box, FOSC
It is the most reliable FOSC with the simplest installation in the world. The FOSC is suitable for protecting fiber cable splices in straight-through and branching applications. Based on an advanced formula, the plastic parts are made of injection-molded, high-strength engineering plastic ABS or 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, compressing, and impacting, bending, tensioning, axial tensioning.
It ensures long-term reliability and usage under ambient temperature from -40 to +65 degree celsius
Purpose: Aerial, direct-burying, wall-mounting, Pipeline laying way
