摘要： It is disclosed an optical cable for communications including at least one micromodule, the micromodule including 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 typically 90% to 95% of an inner diameter of the retaining element. The retaining element consists essentially 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.

摘要： A fire resistant optical cable includes: a plurality of optical fibers; at least one tubular layer of a ceramifiable material surrounding the plurality of optical fibers; and at least one flame shielding layer surrounding the tubular layer. The tubular layer of the ceramifiable material is able to mechanically protect the optical fibers not only during heating but also when the fire is extinguished, since it forms a sufficiently robust layer to withstand the mechanical stresses caused by the collapsing of the materials still surrounding the cable, especially in the transition portions between hot and cold zones. The tubular layer of the ceramifiable material is protected by means of at least one flame shielding layer which prevents the flames from directly acting on the ceramifiable material.

摘要： A telecommunication cable is equipped with at least one optical fiber coated by a tight buffer layer made from a polymeric material having an ultimate elongation equal to or lower than 100% and an ultimate tensile strength equal to or lower than 10 MPa. The above combination of features of the polymeric material forming the buffer layer provides an optical fiber which is effectively protected during installation operations and during use, and at the same time can be easily stripped by an installer without using any stripping tools, simply by applying a small pressure with his fingertips and a moderate tearing force along the fiber axis.
