Description:
Outdoor direct buried fiber cable is a kind of transmission cable which is especially designed to be buried under the ground without any extra covering or piping to protect it.There is steel wires or steel tape at the protection layer of the cable.It can directly buried at the ground,with the function of bearing physical damage and preventing soil corrosion.It can be applied to WAN/LAN telecommunication and harsh environmental conditions such as steep hills, rivers, etc.
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. 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 polyethylene (PE) sheath.
Important notice:
Many domestic small factories use 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 duties on optical fiber cables. The customers cannot claim for any compensation and suffered huge losses.
