Abstract
The invention relates to a roll manufactured with a light waveguide conductor (LWG-conductor), in particular for the transmission of optical signals from and to, respectively, a moving body. A perfect winding construction from which the conductor can be unreeled without interference is obtained in that the LWG-conductor (1) is wound to form a self-supporting cross-roll without a winding core.
