OPGW (COMPOSITE FIBER OPTIC OVERHEAD GROUND WIRE)

OPGW fiber communication system have mayor technical advantages over conventional methods, such as high transmission capacity and freedom from electro-magnetic interference.

 

The construction of OPGW is similar to that  of AS ground wire except that optical fiber cables are placed in the center and protected by head shield tape and aluminum tube. It has the following characteristics :

 

OPGW has low loss, increased band with and electromagnetic interference free properties , witch  produce economical and high fidelity  telecommunication system.
OPGW performs fully all the duties of an overhead ground wires without the loss of performance.
