Product Description
This cable has been designed for long haul duct / backbone application, it is a
Non-Metallic construction cable, its stranded loose tube design provides stable
performance over a wide temperature range and is compatible with any telecommunications-
grade optical fiber. Duct type Fiber Optical Cables 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.
Length markings in meters for easy determination of cable length. Extra Strength
cable can also be delivered with Peripheral Strength Members.
