Shanghai Gengyun Industrial Co., Ltd
The structure of GYFTZA53 loose tube cable is to insert 250 μ m optical fiber into a loose sheath made of high modulus material. 1.250μm single-mode fiber is located in the loose sleeve made of PBT plastic. The gap in the loose sleeve tube is filled with a contact paste compound and located in the center of the whole cable. 2.Multiple metal stiffeners and yarns are wound around the center tube with appropriate pitch, and a waterproof material is applied at the same time. 3.Polyethylene sheath or other materials. Such as low smoke halogen-free polyolefin are tightly coated around the reinforcement.
Packaging
Standard Export Packing
Application
Loose tube cable is suitable for pipeline,overhead, underground;
Product Feature
1.Non-metal strength member;
2. Loose tube cable filler protect loose tuber fiber;
3.Optical cable sheath material (PE) has good anti-ultraviolet radiation performance and environmental stress cracking resistance;
4. The waterproof performance of optical cable ensured by using waterproof material to prevent the longitudinal seepage of optical cable;
5. Optical fiber has large transmission capacity, less loss, long transmission distance, small size, light weight, low dispersion and easy laying;
6. Two parallel wires ensure the tensile strength of the cable, and the suitable temperature of the cable is -40 to +70;
