Flat Twin Duplex Indoor Cable GJFJBV

Flat Twin Duplex Indoor Cable use 900μm or 600μm flame-retardant tight buffer fiber as optical communication medium.
The tight buffer fiber wrapped with a layer of aramid yarn as strength member units,such unit is extruded with a layer of PVC or LSZH material as inner jacket.
