FTTH Drop Cable/ftth optical fiber Single Mode 4 Core Indoor/Outdoor Ftth G657A Lszh Fiber Optical Cable
Product Description
Characteristics
1. Special low bending sensitivity optical fiber provides high bandwidth and excellent communication transmission performance;
2. Two parallel FRP reinforcements ensure good compressive performance and protect fibers;
3. A single steel wire or massager is used as an additional reinforcement to ensure good tensile strength;
4. Simple structure, light weight and strong practicability;
5. Novel chip removal groove design, easy disassembly and easy installation and maintenance;
6. Low smoke, zero halogen, flame retardant sheath.
Applications
1. Used in access network or as access cable from outdoor to indoor in customer premises network;
2. Used as access building cable in premises distribution system, especially used in indoor or outdoor aerial access cabling.
