GYTFY53 Armored Fiber Optic Cable For Direct Burial

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), sometimes sheathed with polyethylene (PE) for cable with high fiber count, locates in the center of core as a delectric strength member. Tubes (and fillers) are stranded around the strength member into a compact and circular cable core. The cable core is filled with the water blocking tape to protect it from water ingress, over which a thin PE inner sheath is applied. After the PSP is longitudinally applied over the inner sheath, the cable is completed with a PE outer sheath.
