ABSTRACT:
The invention relates to a method of manufacturing an optical line, in which at least one LWG (4, 11, 15, 19) extends in an envelope (3, 9, 13, 18) with excess length and is fixed with respect to the envelope by positioning elements (7, 8, 12, 20). The adjustment of an exactly defined excess length of one or several LWGs is made possible without the use of expensive manufacturing devices in that the positioning elements (7, 8, 12, 20) are provided on the LWGs (4, 11, 15, 19) prior to or during the insertion in the envelope (3, 9, 13, 18) and that the LWGs are pulled in by unreeling forces acting on the envelope (3, 9, 13, 18).
