  • Apparatus for manufacturing an optical cable and cable so manufactured
    Patent number: 8406590
    Abstract: A method and apparatus for manufacturing an optical cable comprising at least one metal tube housing at least one optical fiber and having a predetermined excess fiber length (EFL) is described. In this method the metal tube is plastically deformed and shortened by a predetermined amount (St) greater than the predetermined EFL and is plastically deformed after shortening to provide a controlled elongation thereof so as to reach the predetermined excess fiber length. An optical cable so manufactured has a local excess fiber length (EFL) varying of or less than 0.2% along the longitudinal extension of the cable with respect to an average EFL of the cable.
    Type: Grant
    Filed: March 6, 2012
    Date of Patent: March 26, 2013
    Assignee: Prysmian Cavi e Sistemi Energia S.r.l.
    Inventors: Luis Sales Casals, Flavio Sangalli, Francesco Della Corte, Alessandro Ginocchio
