Dome Fiber Optic Splice Closure GPJ83-D18


The GPJ83-D18 Dome Fiber Optic Splice Closure are closures which accommodate the joint part of the cable, that can be used in aerial-hanger, wall-mounting or pole-mounting. This kind of dome splice closure includes three types, namely GPJ83-D18-A, GPJ83-D18-B, GPJ83-D18-C, GPJ83-D18-D, which differs from sizes, input/output ports numbers, capacity, etc. The box is made from the high-quality PC and with the mechanical Sealing Structure filled with Silicon Gum Material. It can be opened after sealing and can be reused.


LongXing GPJ83-D18 fiber optic splice closures are specially designed to protect joints of optic cable.
The scope of application is: aerial, wall-mounting, and pole-mounting. The ambient temperature ranges from –40℃ to +65℃.
The closure adopts mechanical and heat shrinkable sealing structure. There is one oval shaped cable port entrances in base, which is used for the sealing of uncut straight-through fiber cable. The small ports are used for branch fiber cable and drop cable.
To adopt engineering PP plastic with high-strength to make the closure has longer life time and excellent sealing performance.
It can be installed more splitter trays and 1:8 blockless or bare PLC splitters.
There are different drop cable elements to be chosen: D18-A: (Φ5-Φ9). Max. 24 pcs drop cable input/output; D18-B: (Φ5-Φ9). Max. 24 pcs drop cable input/output; D18-C: (Φ5-Φ9). Max. 32 pcs drop cable input/output. D18-D: (Φ5-Φ9). Max. 32 pcs drop cable input/output.
The excellent sealing structure keep good sealing performance after re-entry and re-using.
It could save installation time.
