ApplicationSingle jacket loose tube cable with a dielectric central strength member, reinforced with glass yarns and polyethylene jacket, designed for outdoor applications, for direct installations in duct. The cable is supplied in UV resistant high density polyethylene (HDPE) duct.
Construction
Up to 12 optical fibers are enclosed in a polybutylene terephthalate (PBT) tubes.
Up to 24 tubes are stranded around jacketed dielectric central member together with PE fillers to form the cable core.
The fibers and tubes are color coded for easy identification.
All the interstices in the cable core are filled with a water blocking materials to prevent water penetration. Water swelling glass yarns are laid over the cable core to serve as peripheral dielectric strength members.
A polyethylene jacket extruded over the glass yarns provides the final cable shape and protection. A ripcord is provided under the jacket to facilitate its removal.
The cable is inserted into UV resistant high density polyethylene duct for wide range of uses including extreme temperatures, abrasive and high tension applications in underground installations.
