Fiber Optic Splice Closure GJS-HB4-4HS



Fiber Optic Splice Closure (FOSC), is for the protection of the fiber splice joint between two or more cables, for direct or branch connection, to prevent the aging caused by the heat, cold, light, oxygen and microorganisms in nature. With the excellent mechanical strength, the robust shell, and the main structures could withstand the worst environmental changes, meanwhile, the vibration, impact, cable stretching and twist could be protected. It could be used for aerial, pipe-lined, direct buried installations.



Environmental conditions


  • Working temperature: -20℃ -+60℃
  • Storage temperature: -40℃~ +65℃
  • Working relative humidity: not more than 80% (at +30℃)
  • Storage relative humidity: not more than 80% ≤ 90%~ 96%(40℃ ±2℃)
  • Atmospheric pressure: 70 ~ 106kpa




  • The closure body is made from imported strengthening plastic with anti-aging agent, and all the external fasteners are all made of
  • stainless steel and copper.
  • The splice trays are designed as overturning structure, and no need to disassemble the other trays during operation.
  • Unique sealing design, with good air-tight, waterproof and re-entry performance;
  • Suitable for the connection of bundle and ribbon optical cables.
