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. Loose tubes filled with water proof compound to ensure compact and longitudinally water blocking, then warpped by aluminum tape. This part of cable accompanied with the wires as the supporting part are completed with a polyethylene(PE) sheath to be figure 8 structure.
