Outdoor GYTA33 Steel Wire Fiber Optic Cable 2-288 Core 25D 12.5D for Underwater Crossings
GYTA33 Fiber Optic Cable
,Steel Wire Fiber Optic Cable
GYTA33 optical cable is made by inserting SM/MM optical fiber into a loose tube, and the tube is filled with waterproof compound. The center of the cable core is a metal reinforcing core. A layer of polyethylene is extruded outside the reinforcing core. The loose tube is twisted around the central reinforcing core to form a compact circular cable core. The gaps in the cable core are filled with water-blocking fillers. . After being wrapped longitudinally with plastic-coated aluminum tape (APL), a layer of polyethylene inner sheath is extruded, and then armored with single or double layers of fine round steel wire, and finally the polyethylene outer sheath is extruded to form a cable.
