The bers, 250m，are positioned in a loose tube made of a high modulus plastic. The tubes are lied with a water-resistant Iling compound.A Fiber Reinforced Plastic (FRP) locates in the center of core as a non一metallic strength member. The tubes (and Hers) are stranded around the strength member into a compact and circular core. After an Aluminum Polyethylene Laminate (APL) moisture barrier is applied around the cable core, the cable is completed with a PE sheath.

Good mechanical and temperature performance

High strength loose tube that is hydris resistant

Special tube filling compound ensure a critical protection of fiber

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 filling compound

 3.100% cable core filling

 4.APL moisture barrier
