The fibers, 125μm, are positioned in a loose tube made of a high modulus plastic.

The tubes are filled with a water-resistant filling compound.

The tube is wrapped 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 polyethylene (PE) sheath.
