The invention relates to a method of producing an optical cable ( ) or a modular unit for an optical cable. According to the inventive method, a metal strip that is drawn off a supply reel is gradually shaped to an open seam tube. At least one optical waveguide ( ) is drawn off a second supply reel and introduced into the open seam tube.
