Direct Burial Fiber Optic Cable is designed for being buried outdoor. The fibers are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water-resistant filling compound. A steel wire, sometimes sheathed with polyethene (PE) for cable with high fiber count, locates in the center of core as a dielectric strength member. Tubes (and fillers) are stranded around the strength member into a compact and circular cable core. The cable core is filled with water blocking tape to protect it from water ingress, over which a thin PE inner sheath is applied. After the PSP is longitudinally applied over the inner sheath, the cable is completed with a PE outer sheath.
Application:
Adopted to Outdoor distribution.
Suitable for aerial duct and buried method.
Long-distance and local area network communication.
Characteristics:
FRP strength. filler protect tube fiber. steel tape armoured.
Good ultraviolet radiation resistant property.
Double sheath. Good moisture-resistance.
