OPTICAL FIBER CABLE WITH DIMENSIONALLY STABLE POLYMERIC COMPONENT

摘要

An optical fiber cable comprising a polymeric component, in particular a buffer tube, is described, suitable for both terrestrial and undersea uses. The polymeric material forming the component comprises a copolymer of propylene with a C4-C8 alpha -olefin and preferably a nucleating agent disbursed therein. The obtained component shows improved dimensional stability, which guarantees its non-deformability, and high transparency and can be extruded at lower extrusion temperatures.
