Abstract
Optical cable comprising a reinforcing tube with diameter less than 7 mm, obtained from a metal strip gradually deformed until it assumes a final configuration with overlapping outer edges, at least one optical fiber arranged loosely in the tube, a water-blocking fluid occupying 75% of the useful internal area of the tube and a plastic sheath around the tube. The water-blocking fluid is deposited when the strip is curved with edges a predetermined distance apart.
