Double Armor Double Guard Outdoor Optical Cable
The structure of GYTA53 optical cable is to insert 250 μm optical fiber into a loose sleeve made of high modulus material, and the loose sleeve is filled with waterproof compound. The center of the cable core is a metal reinforced core. For optical cables with certain core numbers, a layer of polyethylene (PE) needs to be squeezed out of the metal reinforced core. The loose sleeve (and filling rope) is twisted around the central reinforcement core to form a compact and round cable core, and the gap in the cable core is filled with water blocking filler. Plastic-coated aluminum tape (APL) is longitudinally wrapped and a layer of polyethylene inner sheath is extruded, and double-sided plastic-coated steel tape (PSP) is longitudinally wrapped and then extruded into polyethylene sheath to form a cable.
