Abstract

An optical cable (1) comprises a sheath (2) surrounding a cavity (3) and a plurality of substantially parallel modules (4) arranged into said cavity (3) with a filling ratio between 20 and 50%; each of said modules (4) comprises: •four to twelve fibers (9), •A tube (5) surrounding the fibers (9) that comprises a mix of polycarbonate and a low friction polymer, chosen from the group of fluorinated polymers and polyamide; said tube (5) having a ratio between its inner di and outer do diameters between 0.45 and 0.55, and comprising an outer low friction polymer layer (6) having a thickness between 0.05 and 0.15 mm, •A filling ratio of said module 4 greater than 55%.
