Description

ABSTRACT:
An optical fiber cable comprising a cylindrical body and optical fibers which are located, and periodically fixed, in respective grooves in the body. The grooves extend along the length of the body in a helical manner, which may periodically change its sense of rotation. The grooves are either in the surface of the body or in the inner surface of a jacket surrounding the body. The fibers may be fixed after every full turn by means of a wire located in a longitudinal groove which crosses the grooves in which the fibers are fixed. The fibers may alternatively be periodically fixed by means of a longitudinally extending adhesive strip. The whole assembly may be provided with a layer of wound tape and a jacket.
