indoor outdoor Direct Buried single mode underground waterproof Armored optical cable
GYXTZY optical cable is designed for installation in ground including swamps and shallow non-navigable river, in ducts, in pipes, in blocks, in trays, in tunnels, in headers, on bridges and skyways, between and inside buildings.
The cable consists of a single tube with freely laid fibers. The free space is filled with a hydrophobic gel in the optical single tubes. The single tube is spirally covered with the steel wire armor. The free space is filled with a hydrophobic gel between wires. The armor is covered with HDPE sheath.
• Precisely controlled fiber length ensures good mechanical and temperature properties of the optical cable
• The loose tube material itself has good hydrolysis resistance and high strength
• The tube is filled with special grease to provide critical protection for the optical fiber
• Good lateral pressure resistance and softness
• A layer of wrapped steel wire ensures the tensile strength of the optical cable and better protects the loose tube.
• Polyethylene (PE) sheath has good UV radiation resistance
• Small diameter, light weight, easy to lay
