GYTA33 Steel Wire Armored Optical Cable

Description:
GYTA33 [metal strength member, loose tube layer twisted filling type, aluminum-polyethylene bonded inner sheath, fine round steel wire armor, polyethylene sheathed outdoor optical cable for communication] The structure of the optical cable is to put the single-mode or multi-mode optical fiber into a loose tube made of high modulus plastic and filled with waterproof compound. The center of the cable core is a metal strength member. For optical cables with certain core numbers, the metal center strength member is extruded with a layer of polyethylene. The loose tube (and filling rope) is twisted around the center strength member to form a compact and round cable core. The gap in the cable core is filled with water-blocking compound and extruded with aluminum-polyethylene bonded inner sheath. The fine round steel wire is armored and extruded into a polyethylene outer sheath to form a cable.
