Description
The fibers, 250μm，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 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. An Aluminum Polyethylene Laminate (APL) is applied around the cable core, witch is filled with the filling compound to protect it from water ingress. Then，the cable is completed with a PE sheath.
Features
Good mechanical and temperature performance
High strength loose tube that is hydrolysis resistant
Special tube Iling compound ensure a critical protection of ber
Special designed compact structure is good at preventing loose
tubes from shrinking
PE sheath protects cable from ultraviolet radiation
The following measures are taken to ensure the cable watertight
1.Steel wire used as the central strength member
2.Loose tube Iling compound
3.100% cable core Iling
