Optic Fiber Cable 3ins/ 3outs Dome Type Joint Box

Product Name: Dome Splice Closure
Model: JBS 

The JB series is a dome type fiber optical splice closure. 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 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. It ensures long-term reliability and usage under ambient temperature from -40C to +65C

Install: aerial, underground, wall-mounting, Pipeline laying way

Sealing Structure: Heat shrinkable Sealing

Components: Seal tape, Insulation tape, Nylon tie, optical cable heat shrinkable sleeve, mental hook, seal fittings, umeral bar, retaining ring
Seal Performance: After the closures are sealed, then pressurized up to 100KPa±5KPa in water, immersed in 15 minutes, there are no air bubbles; Or observed for 24 hours, there is no change of air pressure.
Re-encapsulation Performance: The closures are pressurized up to 100KPa±5KPa in water, immersed in 15 minutes, there are no air bubbles; Or observed for 24 hours, there is no change of air pressure after three times of repeat encapsulation
Insulation resistance: ≥2X104MΩ                                
Span-life: 30 years.
Application: It is widely used for communication, network system, cabled T.V. of CATV, the fiber optic cable by network
