GJYX(F)CH is the FTTH drop cable with self-supporting. The optical fiber unit is positioned in the centre. Two steel wires (or FRP, KFRP ) are placed at the two sides ,then an additional steel wire is attached to the outside. Finally the cable is completed with a black or white color PVC or LSZH (low smoke, no halogen, flame retardant) sheath.
Features and application:
* Simple structure, light weight and strong practicability.
* Unique groove design, easy to peel off and connect, simplify installation and maintenance;
* A single steel wire with additional reinforcement elements makes the cable have good tensile properties.
*Outdoor aerial
