Outdoor Underground Directly Buried Stranded Loose Tube Cable GYTY53
Outdoor Underground Directly Buried Stranded Loose Tube Cable GYTY53
The loose tube fiber cable are filled with a water-resistant filling compound. A steel wire, sometimes sheathed with polyethylene (PE) for cable with high fiber count, locates in the center of core as a metallic strength member. Tubes (and fillers) are stranded around the strength member into a compact and circular cable core. The cable core is filled with the filling compound 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.
