Loose tube stranded unarmored fiber optic cable (GYTS)

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 (PSP) is longitudinally wrapped and extruded into a polyethylene sheath to form a cable.

 

 Product Characteristics

•  With good mechanical properties and temperature characteristics

•  Material of loose tube has good hydrolysis resistance and high strength

•  The loose tube is filled with special gel, which protect the optical fiber

•  Specially designed compact cable structure to effectively prevent casing from retracting

•  Anti-UV PE out sheath

•  Take the following measures to ensure the waterproof performance of the optical cable

- Single steel wire center reinforced core

- Filled with special Water-blocking material in loose tube

- Complete cable core filling

- Moisture-proof layer of plastic

- Coated steel tape (PSP)
