Construction Features
The GYFXTY central beam tube optical cable structure inserts 250μm optical fiber into a loose tube made of high modulus material, with the loose tube filled with waterproof compound. The loose tube is wrapped with a layer of aramid yarn (Made In China) longitudinally, and water blocking material is added between the aramid yarn and the loose tube to ensure optical cable compactness and longitudinal water blocking. Two parallel steel FRP are placed on both sides and the polyethylene sheath is extruded into a cable.
