GJS--ST24 Horizontal type Fiber Optic Splice Closure with 3 inlets/outlets
Innovative design is horizontal type with one hinge in one side and open in another side. It is the most reliable FOSC 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 +75℃
Purpose: aerial, direct-burying, wall mounting, Pipeline laying way
Dimension (CM): 44*22*110CM
Cables Entry & Exit:3Entry 3Exit
Cable Diameter (mm): Φ7-Φ30
Sealing Structure: silicon gum material Sealing
Maximum capacity: Bunchy 12-144cores; Ribbon: 288 cores
It is widely used for communication, network system, cabled T.V. of CATV, the fiber optic cable by network
Suitable for aerial, pipelined or direct buried applications; suitable for common fiber cables and ribbon cables; suitable for straight-through as well as for branch joints to seal and protect splice, fusion, layout and storage of the fiber cables
