A plug connection for connecting a light waveguide to a plug has a plug member with a connecting light waveguide extending from one side thereof having an end being spliced to a light waveguide of a light waveguide cable and at least one strain relief element being passed over the splice and connected to the plug member. The method of forming the plug connection includes providing a sufficient length of both the connecting light waveguide extending from the plug member and the light waveguide of the cable so that a connection in a normal, known splicing apparatus can be obtained outside of the position of the plug member and then conducting the strain relief element over the splice region and connecting it to the plug member.

Optical cable with at least one optical waveguide

An optical cable comprising a carrier member extending in a longitudinal direction and having outwardly accessible chambers receiving light waveguides, each of said chambers being separated from one another by a web characterized by a depression being formed in each of said webs to enlarge the heat-emitting surfaces and to remove undesirable accumulation of material in the region of the carrier members. The depressions preferably have a V-shaped cross section, and are smaller than the channels and are able to receive additional elements, which may include waveguides, tensile elements or electrical conductors. Each of the V-shaped depressions can also e used as a gas channel when the optical cable is to operated in a gas-pressure monitored fashion.

In the processing of light waveguides, a method uses an overhead haul-off from a first supply reel to apply a pre-twist to the light waveguide, which is preserved during a tinting operation and while the tinted waveguide is wound in a tangential direction on a second supply reel. During further processing, in acordance with the present method, the waveguide is taken off by an overhead haul-off process from the second supply reel in a direction of haul-off which is opposite to the direction during the first overhead haul-off so that the twist produced by the second overhead haul-off is in an opposite direction and compensates for the twist produced during the first overhead haul-off operation.
