    Description

    Overview

    In the GYTA53 direct buried fiber optic cable, 250um fibers are wrapped around a phosphatized steel wire central strength element and held in gel-filled PBT loose tubes. The loose tube is filled with a waterproof substance, and the cable core is metal reinforced in the center. A layer of polyethylene must be extruded outside the metal-reinforced core for some direct buried fiber optic cable. The loose tube coils around the central reinforcing core to form a spherical and compact cable core, with the water-blocking fillers filling the gaps. To construct a 144 core outdoor fiber cable, a polyethylene sheath wraps and extrudes longitudinally through plastic-coated aluminum tape.
