  Underground OPGW cable/optical fiber cable

Description:

OPGW cable has two constructions:

Central loose tube type

The fibers 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 control temperature rise during short circuit conditions. 

 Multi loose tube type

The fibers 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:

Good mechanical and temperature performanceHigh strength loose tube that is hydrolysis resistantSpecial tube filling compound ensure a critical protection of fiberCrush resistance and flexibilityThe following measures are taken to ensure the cable watertight:Single Fiber Reinforced Plastic as the central strength memberLoose tube filling compound100% cable core filling
