Method for manufacturing an optical line (waveguide, optical fibre)

摘要

Method for manufacturing an optical line in which an excess length of at least one optical waveguide is set by shortening an associated supporting element, and in which the supporting element which is provided with the optical waveguide is guided between two supporting elements with a variable depth of sag. Precise measurement of the excess length is made possible in that, during a measurement time interval which is defined by the times at which an identical reference sag depth is identified, on the one hand the fed-in length of the optical waveguide (2) and on the other hand the outgoing length of the shortened supporting element (6) are measured. <IMAGE>
