Product Description

The structure of GYTS optical cable is to put 250µm optical fiber into the loose tube, which is made of high modulus material, and filled with waterproof compound. In the center of the cable core is a metallic strength member,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 steel tape  is longitudinally wrapped and extruded into a polyethylene sheath to form a cable.
