Abstract
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.
