The fibres are posioned in a loose tube made of PBT. The tube is filed with a water-resistant filing compound. A fibre reinforce plastic locates in the center of core as a non-metalic strength member. The tubes ( and the fillers ) are sranded around the strength member into a compact and circular core.And then the core wrapped with the sweling tape longitudinaly. After part of cable accompanied with the stranded wires as the supporting part are completed with a PE sheath to be figure 8 structure.

Installation method:  Lashed
Characteristics:         1.Excellent mechanical and temperature performance
                                  2. Special tube filling compound ensure a critical protection of fibre and resist the water
                                  3.Loose tube strandina cable core ensures the cable structure stable
                                  4. Loose tube completely filling compound to ensure the cable watertight
                                  5. High tensile strength of stranded wires meet the requirement of self-supporting and                                              reduce the installation

                                   6.Outer sheath protects cable from ultraviolet radiation
Applications:               Lona distance and LAN communication
Standards:                   YD/T 901 and lEC 60794-1
