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
Uni-tube gel-filled construction for superior fiber protection.
CST armorto protect cable from rodentattack and mechanical damage.
Embedded steel wire provide desirable tensile strength and crush
resistance.
Compact, easy to install.
