Abstract

An optic fiber cable 1 is disclosed having a reinforced central core 5 on which are helically wound contiguous supports 8 for optical fibers 17, 18, 19 into at least one continuous annular layer. Each support 8 has grooves 14, 15, 16 for the optical fibers on its outer, convex surface 10. Each support is matingly encased by an elastically deformable jacket 9 which holds the optical fibers in their grooves. By imparting axial torsion on the optical fibers before they are laid in their grooves equal and opposite to the torsion imparted by the supports the resultant axial torsion on the optical fibers is nil.
