Fiber Optic Splice Closure GJS-HB4-4A



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




  • 4 Cable entries (2-in & 2 -out), applicable for fiber cables Ф10~21mm;
  • Max. capacity (single fibers): 96fibers;
  • Mechanical sealing, good sealing performance, IP68;
  • Patent design, easy for operation and re-entry; Can be used for single/ribbon fibers;
  • Double internal and external suspension fastening of the fiber cable, to make sure the cable is fixed in the middle and could meet the testing requirements of torsion, tension, pressure and bending etc.;
  • Adequate storage space for uncut fibers and easy for operation;
