FRP Strengthen Direct Burial Outdoor Fiber Optic Cable GYFTY

The fibers, are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water-resistant filling compound. A Fiber Reinforced Plastic (FRP) locates in the center of core as a non-metallic strength member. The tubes (and fillers) are stranded around the strength member into a compact and circular core. The cable core is wrapped with the water blocking tape to protect it from water ingress, then the cable is completed with a PE sheath.
