PBT Loose Tube Optical Ground Wire (OPGW Cable)
Description:
The PBT Loose Tube Optical Ground Wire (OPGW) is surrounded by single or
double layers of aluminum clad steel wires(ACS) or mix ACS wires and aluminum
alloy wires.Usually,there are 4 PBT loose tubes inside the aluminum tube,each PBT loose tube 12 cores,this structure is widely used in South America,Africa and some old communication lines upgrading.
OPGW has two fiber type:one is single mode G652D and the other is G655,sometimes they mixed together,such likeOPGW-36B1+12B4-93 [78.8;53.9]. Fiber optic cable OPGW, usually 12~48 fibers,can max produced 96 fibers OPGW fiber optic cable,jelly filled and fiber contained central PBT loose/aluminum cladding steel/aluminum tube, outer with AA/ACS wires armored, detailed specification on your request.
