The filbres are positioned in a loose tube made of PBT. The tube is filled with a water-resistant filing compound and amroured with a layer of PSP longitudinally, Between the PSP and the loose tube water-blocking material is applied to keep the cable compact and watertight. Two parallel steel wires are placed at the two sides of the steel tape. The cable is completed with a PE sheath.

Installation method: Inside tube, Lashed, Direct buried
Characteristics:  1.Excellent mechanical and temperature performance
                           2. Special tube filling compound ensure a critical protection of fibre and resist the water

                           3. Better Anti-water performance by the swell tape
                           4. Corrugated steel ensure the water blocking and lateral crush resistance performance

                           5.Two parallel steel wires ensure tensile strength

                           6.Outer sheath protects cable from ultraviolet radiation
Applications:      LAN communication and FTTx
Standards:          YD/T 769 and lEC 60794-1
