Single Mode Multi Mode Armoured GYXTW G657A G652D Fiber Optic Cable
2/4/6/8/12/16/24 Core Single Mode Multi Mode Outdoor Armoured GYXTW G657A G652DFiber Optical Cable
Description
The fibers, 250μm, are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water-resistant
filling compound. The tube is wrapped with a layer of PSP longitudinally. Between the PSP and the loose tube water-blocking
material is applied to keep the cable compact and watertight. Two parallel steel wires are placed at the two sides of the steel
tape. The cable is completed with a polyethylene (PE) sheath.
Product features:
1. Small outer diameter, light weight and convenient construction
2. Stable fiber excess length control
3. After the cable is formed, the additional attenuation of the fiber is almost zero, and the dispersion value does not change
4. Excellent environmental performance
Structural feature:
1. Central loose tube protects once coated optical fiber
2. The optical fiber is concentrated in the center of the cable, and the reinforcements are distributed on both sides of the cable
sheath
3. A water blocking layer is provided between the steel belt and the cable core
4. Double-sided plastic-coated corrugated steel tape-polyethylene bonded outer sheath
5. Double steel wire parallel reinforcement
