GYCFTY cable structure is a loose sleeve made of high modulus material with 250 micron optical fiber. The loose sleeve is filled with waterproof compound. The loose sleeve is reinforced around the non-metallic center to form a compact circular core. The waterproof yarn with moisture-proof effect is placed in the gap of the cable core, and then the polyethylene sheath is extruded into the cable.
♦ Small diameter, light weight, moderate hardness and softness, easy to bend when air blowing laying, easy to operate;
♦ All non-metallic structure, no need of grounding, long air blowing distance;
♦ Make full use of pipe hole resources, use air-blown laying facility to speed up construction, and lay a long distance at a time;
♦ With the growth of communication business, it can be blown into optical cables in batches, and the investment can be carried out step by step, so as to reduce the early investment;
♦ Micro-cables can be blown out to facilitate the replacement of new types of fiber optic cables in the future and keep ahead in technology;
♦ Suitable for construction in crowded metropolitan area network pipelines, avoiding destructive excavation in the past;
♦ Suitable for backbone network, metropolitan area network and access network;
