Non Metallic GYFTY Fiber Optic Armoured Cable G652D 48 Core PE HDPE
The center of GYFTY’s optical cable is a glass fiber reinforced plastic (FRP). A loose tube (and a filling rope) is twisted around the center reinforcing core to form a compact and round cable core. The gap in the cable core is filled with a water blocking filler. The outer layer of the cable core is extruded with a polyethylene inner sheath to form a cable.
