The instruction of GYFTS armored fiber optic cable is the single mode or multimode inserted to loosely tube by high the plastic of moudle. Filling warting blocking material in the tube. One single metal strength member is in the mid of cable, added a layer of polyethylene sheath on it for some cores of fiber cable(if necessary). loose tube and filling compound tightly tied up with center metal strength member roll to be cylindrical cable. Packed with PE sheath after armored Al-plastic tape. Packed with PE sheath after double armored polyethylene steel.

DESCRIPTION
1. The GYFTS cable structure is a loose sleeve made of 250 micron optical fibers embedded in high modulus materials, and the loose sleeve is filled with waterproof compounds.
2. The center of the cable core is a non-metallic reinforcement core.
3. The loose sleeve (and filling rope) is twisted around the core to form a compact and circular core.
4. The gap in the core is filled with water-blocking filler.
5. Plastic-coated steel strip (PSP) is longitudinally wrapped and then extruded into a polyethylene sheath cable.
FEATURES
1. Excellent mechanical and temperature performance.
2. Special tube filling compound ensure a critical protection of fiber and resist the water.
3. 100% core filling with water-blocking material to ensure the cable water-proof.
4. Single FRP as the central strength member to withstand axial loads.
5. Outer sheath protects cable from ultraviolet radiation.
