Abstract
An optical fiber cable intended for submarine use has a central cylindrical strength member (1) over which are laid the optical fibers (2). These are within a sheath 3, itself within an aluminum tube (4), usable to convey electrical power for repeaters. On the outside of this tube we have a layer of high tensile steel wires (5), surrounded by a layer of low density polyethylene. In a cable for shallower waters where the risk of damage is greater than in deep water the polyethylene layer is surrounded by a layer of armouring wires separated from the polyethylene by bedding material and enclosed by a layer of binding material.
