GCYFXY MINI Central Bundle Tube Air-Blown Optical Cable


GCYFXY central tube air-blown micro-cables are made by placing optical fibers in loose sleeves made of high modulus materials, filling them with non-toxic and harmless waterproof compounds, placing reinforcement elements aramid outside loose sleeves as required, and then extruding low friction coefficient sheaths.


♦ light in weight, moderate in hardness and softness, easy to bend when air-blown laying, and easy to operate.           

♦ All non-metallic structure without earthing           

♦ With the growth of telecommunication business, it can be blown into optical cable in batches, and the investment can be carried out step by step, so as to reduce the initial investment.           

♦ Micro-cables can be blown out to facilitate the replacement of new types of optical fibre cables in the future and keep ahead in technology           

♦ Suitable for construction in crowded MAN pipelines, avoiding destructive excavation in the past           

♦ It is not necessary to determine the divergent position of the connecting box and the optical cable beforehand. Without affecting the normal operation of other optical cables, the external protective tube and the microtubules can be cut off at any time and anywhere to diverge the optical cables. At the same time, the number of manholes, hand holes and connecting joints can be saved and the comprehensive cost can be reduced.
