GYFTC8Y 4 Core Dielectric Fiber Optic Cable Specification

Short Description:

The optical fiber is 250µm, the loose tube is made of high modulus plastic, which is filled with waterproof compound. The center of the cable core is a metal reinforced core, Tubes (and fillers) are stranded around the strength member into a compact and round cable core, which is filled with the waterproofing compound to protect it from water ingress. Plastic coated aluminum tape or steel tape is longitudinally wrapped and extruded into a polyethylene sheath to form a cable.With self-supporting messenger wire.
