Abstract

It is disclosed an optical cable for communications comprising at least one micromodule, the micromodule comprising a retaining element and number N of optical fibers housed in said retaining element. The diameter of a circumference encircling the number N of optical fibers is 90% to 95% of an inner diameter of the retaining element. The retaining element is made of a film grade polymeric 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.
