China Aramid Building Access Cable Manufacturer, Supplier, Factory

The structure of uni-tube light-armored fiber optic 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 loose tube is longitudinally wrapped with a layer of double-sided plastic-coated steel belt (PSP), and water-blocking material is added between the steel belt and the loose tube to ensure the compactness and water-blocking performance of the optical cable. Two parallel steel wires are placed on both sides and then a polyethylene sheath is extruded to form a cable.

The structure of stranded loose tube armored fiber optic 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. A layer of polyethylene inner sheath is extruded outside the cable core, and a double-sided plastic-coated steel tape (PSP) is longitudinally wrapped and then extruded into a polyethylene sheath to form a cable.

Flat fiber ribbon fiber optic cable uses optical fiber ribbon as the optical transmission medium, covered with a layer of aramid as a force-reinforced unit, and extruded with a layer of polyvinyl chloride (PVC) or low-smoke zero-halogen material (LSZH, low-smoke, halogen-free, flame-retardant) sheath.

Multi-mode Optical Fiber OM1 (62.5/125μm) meets or exceeds the ISO/IEC 11801-1 OM1 specification, IEC 60793-2-10 A1-OM1 specification, and TIA-492AAAF A1-OM1 specification.
