OPGW optical fiber cable manufacturer

OPGW cable has two constructions:

1.Central loose tube type

OPGW fiber optic cable 24 core  is placed loosely in a sealed and water resistant stainless steel tube filled with water blocking gel. This tube provides protection to the fiber during installation and operation under severe environmental conditions. Aluminium layer over the tube is optional. The stainless optical tube is located at the center of the cable protected by single or multiple layers of aluminium clad steel and aluminium annoy wires. The aluminium clad steel wires are shaped trapezoidally around the optical unit to provide compact construction. The metallic wires provide mechanical strength to withstand severe installation and operating conditions, while achieving conductivity to controltemperature rise during short circuit conditions. 

2.Multi loose tube type

OPGW fiber optic cable 24 core  is placed loosely in a sealed and water resistant stainless steel tube filled with water blocking gel. Two or three stainless steel optical tubes are helically stranded in the inner layer of a multiple-layer cable. The multi loose tube type is designed mostly for very high fiber count requirement over 48 with the maximum fiber count reaching 144. The multi loose tube type can meet the requirement of huge cross and large current capacity.  

Features:

• Fiber counts up to 432 or higher if needed

• Laser-welded, hermetically sealed stainless steel tubes provide mechanical and thermal protection for optical fibers

• High load, long span capability

• Each stainless steel tube is uniquely identified for organization at splice locations

• Stranded wires selected to optimize mechanical and electrical properties of cable

• Anti-rotational devices usually not required for installation, depending on conditions

Applications:

• For use by electric utilities on transmission lines in lieu of traditional shield wire

• For retrofit applications where existing shield wire needs to be replaced with OPGW

• For new transmission lines in lieu of traditional shield wire

• Voice, video, data transmission

• SCADA networks

• Dark fiber leasing
