Optical Cable for Communication and Process for the Manufacturing Thereof

A micromodule (1) for an optical cable for communications (5), comprising:

• a retaining element (3) and a number N of optical fibers (2) housed in said retaining element (3), wherein:
• a diameter of a circumference (C) encircling said number N of optical fibers (2) is 90% to 95% of an inner diameter (ID) of said retaining element (3);
• and
• said retaining element (3) consists essentially of a film grade material having an elongation at break equal to or higher than 500%, a melt flow index MFI lower than 3 g/10 min, and a density lower than 1 g/cm3.

A process for manufacturing a micromodule (1) for an optical cable for communications (5), said process comprising:

• providing a number N of optical fibers (2);
• and
• providing a retaining element (3) around said number N of optical fibers (2) thus forming said micromodule (1),
• wherein providing a retaining element (3) comprises extruding a film grade material, said film grade material having an elongation at break equal to or higher than 500%, a melt flow index MFI lower than 3 g/10 min, and a density lower than 1 g/cm3, wherein the diameter of a circumference (C) encircling said number N of optical fibers (2) is 90% to 95% of an inner diameter (ID) of said retaining element (3).
