Brief:The GYFY outdoor loose tube layer stranded non-metallic optical cable involves inserting optical fibers into loose tubes made of high-modulus PBT material with internal water-blocking yarn. The center of the cable core is a non-metallic reinforcement core, and for certain fiber counts, an additional layer of polyethylene (PE) is extruded around the non-metallic reinforcement core. The loose tubes (and filler yarns) are stranded around the central reinforcement core to form a compact circular cable core. Inside the cable core, water-blocking yarn and water-blocking tape create a dry water-blocking layer. The cable core is then sheathed with polyethylene (PE).
Brief:GYFS fiber optic cable is a fully dry-type cable that adopts a loose layer twisted structure, with non-metallic reinforced cores (such as FRP) providing tensile strength, and achieves a fully dry-type waterproof design through special waterproof yarns and waterproof tapes, replacing the traditional oil paste filling method.
Brief:ADSS fibre optic cable is a loose-jacketed, laminated construction, with 250µm of fibre optic cable placed in a loose tube of high modulus material, filled with a waterproof compound. The loose sleeving (and filler rope) is twisted around a non-metallic central reinforcement core (FRP) to form a compact core with gaps filled with water-blocking grease. The inner sheath of polyethylene (PE) is extruded outside the core, then the reinforcing aramid is stranded and the outer sheath of PE or AT is extruded.
Brief:The GYXTW fibre optic cable is constructed by placing 250μm fibres in a loose tube made of high modulus plastic.. The tubes are filled with a waterresistant filling compound. The tube is wrapped with a layer of PSP longitudinally.Between the PSP and the loose tube waterblocking 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 PVC or PE sheath.
Brief:GYTZA53+33 optical cable is an armored cable designed specifically for complex outdoor environments, with flame retardant, moisture-proof, and tensile properties, suitable for steep slopes, river crossings, and other scenarios.
Brief:The structure of GYTS optical cable is to insert 250 µm 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 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) is twisted around the center strengthening core to form a compact and circular cable core, and the gaps inside the cable core are filled with water blocking fillers. Double sided coated steel strip (PSP) longitudinally wrapped and extruded into polyethylene.
Brief:The GYTC8S(A) fibre optic cable is constructed by placing a 250µm fibre optic cable into a high modulus material pine tube, which is filled with a waterproof compound. At the centre of the cable core is a metal reinforcement core, around which the loose tube (and filler rope) is twisted to form a compact and round core.The core is wrapped longitudinally with a layer of plastic coated aluminium tape (APL) / (PSP) and integrated with the wire strands in a polyethylene sheath in the shape of a figure of eight.
Brief:The GYTA53 fibre optic cable is constructed by placing a 250µm fibre optic cable in a high modulus material pine tube, which is filled with a waterproof compound. At the centre of the core is a metal reinforcement core, which for some cores is also extruded with a layer of polyethylene (PE). The loose sleeving (and filler rope) is twisted around the central reinforcement to form a compact and rounded core with gaps filled with a water-blocking filler. Plastic coated aluminium tape (APL) is wrapped longitudinally and then extruded with a layer of polyethylene.
Brief:GYTA fibre optic cables are constructed with 250µm fibre optic fibres in a high modulus material pine tube, which is filled with a waterproof compound. At the centre of the core is a metal reinforcement core, which for some cores is also extruded with a layer of polyethylene (PE). The loose sleeving (and filler rope) is twisted around the central reinforcement to form a compact and rounded core with gaps filled with a water-blocking filler. Plastic coated aluminium tape (APL) wrapped longitudinally and then extruded with a polyethylene sheath.
