Stranded Loose Tube Non-armored Fiber Optic Cable Cable

The structure of stranded loose tube non-armored fiber optic cable cable is to put 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 reinforcement core. For optical cables with certain cores, a layer of polyethylene (PE) needs to be extruded outside the metal reinforcement core. The loose tube (and filling rope) are twisted around the central reinforcement core to form a compact and round cable core, and the gaps in the cable core are filled with water-blocking fillers. The plastic-coated aluminum belt or steel belt is longitudinally wrapped and extruded into a polyethylene sheath to form a cable.
