GYXTW 8 Strand Singlemode Armored Black Fiber Optic Cable for outdoor use
Description
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. A corrugated steel-plastic composite belt with waterproof material and longitudinal lap is applied outside the center pipe.
3. A layer of black polyethylene sheath with parallel steel wire reinforcement or other materials such as low smoke halogen-free polyolefin is tightly covered around the moisture barrier layer.
Product Construction
Fiber:
2-24 fibers
Uni-loose tube gel-filled
Armor:
Corrugated steel tape
Strength Member:
Embedded steel wire
OuterJacket:
Black UV-and moisture-resistant polyethylene (PE).
Product Characteristics
1. Material of loose tube has good mechanical properties and temperature characteristics
2. Material of loose tube has good hydrolysis resistance and high strength
3. The tube is filled with special filler to provide critical protection for the fiber
4. Good lateral pressure resistance and softness
5. Double chrome plating plastic-coated steel tape (PSP) improves the moisture resistance of optical cables
6. The two parallel steel wires provides enough tensile strength
7. Small diameter, light weight, easy for laying
Features
