FTTH G657A Access Building Fibre Optic Cable
Suitable Application :
- Backbone distribution cable for FTTH Networking, Fibre Optic Telecommunication System, Fibre Optic Local Area Network.
Description :
- Optical fibres were positioned in a loose tube made of high modulus plastic that provide reasonable crush resistance and flexibility to the cable. Hydrolysis resistance high strength loose tubes are filled with water-resistance compound filling. The loose tube is cover with a layer of aramid yarn as strength member to ensure tensile strength. The cable is completed with LSZH (Low Smoke, Zero Halogen, Flame-Retardant) jacket. The cable was specially designed with smaller diameter, light weight and provide excellent mechanical and temperature performance.
