Product Description

Outdoor direct buried optical fiber cable is a kind of transmissions cable which is especially designed to be buried under the ground without any extra covering or piping to protect it. There has corrugated steel tape or steel wires as the armed layer of the cable, which can bear physical damage and prevent soil corrosion. Outdoor direct buried optical fiber cable is applied to WAN/LAN telecommunication and harsh environmental conditions such as steep hills, rivers, etc.


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 duties on optical fiber cables. The customers cannot claim for any compensation and suffered huge losses.
