24F SM G652D Direct Burial Outdoor Fiber Optic Cable GYFTA53

The fibers, 250μm, are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water-resistant filling compound. FRP locates in the center of core as a non-metallic strength member. Tubes (and fillers) are stranded around the strength member into a compact and circular cable core. An Aluminum Polyethylene Laminate (APL) is applied around the cable core, which is to protect the cable from water ingress. Then the cable core is covered with a thin PE inner sheath. A layer of kevlar yarn is applied to increase the tensile strength. After the PSP is longitudinally applied over the kevlar yarn, the cable is completed with a PE outer sheath.
