Abstract
This invention is a fibre optic communication cable in which the signals are transmitted by light. The glass fibres used for the cable are protected from breaking strain and from excessively sharp bends by supporting helically wound optic fibres on the inside of a tension element with provision by which the diameters of the helical convolutions can become smaller to increase the axial length component of the optic fibres when the a axial length of the tube is increased by forces that strain the tube. Several ways of maintaining the helically wrapped optic fibres supported from the tube so as to permit decrease in the diameter of the helix are described and illustrated.
