Abstract
An optical fiber submarine cable includes a fiber optic bundle sealed within a precompressed electrically conductive tube defining a hermetic cavity. An inner layer of helically wound copper-plated steel wires is disposed around the electrically conductive tube. An outer layer of oppositely helically wound copper-plated steel wires is preferably disposed around the inner layer. The wires are tightly wound at a pitch of between 8.degree. and 20.degree. and the outer wires balance the torque from the inner wires. An insulation layer of polyethylene surrounds the outer armor layer. A method of making the cable uses precompression of the tube to increase the strength of the cable.
