Direct Buried Cable GYTA53

　　The Direct Buried Double Armor Double Jacket Fiber Optic Cable GYTA53 is specifically designed for direct burial, allowing it to be buried directly in the ground without the need for extra protective ducts or conduits. This feature simplifies the installation process and reduces infrastructure costs. 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. A steel wire, sometimes sheathed with polyethylene (PE) for cable with high fiber count, locates in the center of core as a metallic 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 filling compound 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.
