Fiber Optic Splice Closure GJS-DM4-6



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.
