Outdoor Central LooseTube Unitube 2 4 6 8 core Optical Fiber Cable TOEM
The structure of GYDTA optical cable is to wrap 4, 6, 8, and 12 core optical fiber strips into loose sleeves made of high modulus materials, and fill the loose sleeves with waterproof compounds. The center of the cable core is a metal reinforced core, and for certain numbers of optical cables, a layer of polyethylene (PE) needs to be extruded outside the metal reinforced core. The loose sleeve and filling rope are twisted around the center to strengthen the core and form a compact and circular cable core. The gaps inside the cable core are filled with water blocking fillers. Plastic coated aluminum strip (APL) is longitudinally wrapped and extruded into a polyethylene sheath to form a cable.
The loose tube central unitube optical cable is protected with steel wire armor which provide high tensile resistant, crush resistant and rodent resistant. The corrugated steel tape is applied reinforcing crush resistant. Outer sheath is made of UV resistance PE jacket. Central unitube outdoor fiber optic is ideal for all external environments including direct burial, tunnels and heavy-duty ducts.
The Loose Tube central unitube optical cable, 250μm,are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water-resistant filling compound. The tube is wrapped with a layer of PSP longitudinally.
Between the PSP and the loose tube water-blocking material is applied to keep the cable compact and watertight. Two parallel steel wires are placed at the two sides of the steel tape.The cable is completed with a flame-retardant sheath.
