Direct Burried Optical Fiber Cable

This cable has been designed for long haul direct / backbone application. Our stranded loose tube design provides stable performance over a wide temperature range and is compatible with any telecommunications-grade optical fiber. Direct buried type fiber optical cable are designed for easy and economical installation.

The stranded loose tubes contain thixotropic jelly but the cable core is based on dry-block construction. Incorporation of dry water block technology eliminates the need for traditional jelly filled water blocking methods, thus providing efficient and craft-friendly cable installation.

The thixotropic jelly is used to fill the buffer tubes to prevent water ingress. Steel tape armoring provides a rodent protection, length markings in meters for easy determination of cable length. Extra strength cable can also be delivered with peripheral strength members.
