Purchasing Risk
Many domestic small factories used inferior or waste optical fibers to imitate A-grade optical fibers, non-woven fabrics as water-blocking tapes, waste electric-wires and rubber slippers smashed as raw materials for the outer sheath of cable. Those inferior cables will cause many problems such as short transmission distance, low bandwidth, intermittent signal and easy-to-crack and water seepage of the cable jacket, etc. For the recent years, there are many cases that many overseas customers who bought such inferior cables from China were frustrated to find that the cables can not be used after constructing. It’s not workable to return them to China as the Chinese government will levy high import duty on optical fiber cables. The customers cannot claim for any compensation and suffered huge losses.
The fibers, 250μm, are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water-resistant filling compound. A Fiber Reinforced Plastic (FRP) locates in the center of core as a non-metallic strength member. The tubes (and fillers) are stranded around the strength member into a compact and circular core. After the cable core is filled with the filling compound to protect it from water ingress, the cable is completed with a PE sheath.
