Optical cable gyta manufacturing process and characteristics The structure of GYTA optical cable is to insert 250μm optical fiber into a loose tube made of high modulus material, and the loose tube is filled with waterproof compound.
The center of the cable core is a metal reinforcing core. For optical cables with certain core numbers, a layer of polyethylene (PE) needs to be squeezed outside the metal reinforcing core.
The loose tube (and filling rope) is twisted around the central strengthening core into a compact and round cable core, and the gaps in the cable core are filled with water-blocking filler.
The plastic-coated aluminum strip (APL) is wrapped longitudinally and then extruded with a polyethylene sheath to form a cable.
Production process: 1. Precisely controlling the excess length of the optical fiber ensures that the optical cable has good tensile properties and temperature characteristics.
2. The loose tube material itself has good water resistance and high strength. The tube is filled with special grease to provide critical protection for the optical fiber and has good pressure resistance and flexibility.
3. PE sheath has good UV radiation resistance and environmental stress cracking resistance.
4. The following measures are adopted to ensure the waterproof performance of the optical cable: Features: a) Single steel wire center reinforcement; b) Loose tube filled with special fiber paste; c) 100% cable core filling; d) GYTA double-sided plastic-coated aluminum tape (APL) improves the moisture-proof ability of optical cables; e) Good water-blocking materials prevent longitudinal water seepage of optical cables.
