12 Core Direct Buried Underground GYTA53 Fiber Optic Cable
Introduction:
The fibers, 250um, are positioned in a loose tube made of a high modulue plastic. The tubes ate filled wth a water-resistant filling compound, A steel wire located in the center of core as a metallic strength member into a compact and circular cable core. An Aluminium Polyethylene Laminate (APL) is applied around the cable core. Which is filled with the filling compound to protect it fron water ingress. Then the cable core is covered with a PE outer sheath. After the single steel armored, the cable is finally completed with an outer sheath.
