ABSTRACT:
An electro-opto-mechanical cable includes at least one thinwall steel alloy tube containing at least one single mode fiber and a void filling gel to assure the capability for transmitting low-noise optical phase data. A dielectric annulus and an electrically conductive layer disposed therein helps further assure watertight integrity and power or electrical signal transfer. An optional double-layer contrahelical or three or four layer, torque balanced, steel wire strength member provides additional protection as well as capability to be towed, deployed and recovered from the seafloor at abysmal depths. The steel armor and cable core interface eliminates all intersticial spaces associated with the armor wires to produce a firm, hard cable that experiences minimal residual strain (creep) due to extensive load cycling. A pressure extruded outer jacket aids in assuring the protection of the individual steel wires from point loadings and from strength degradation due to corrosion. Further, the integral steel armor and jacketing structure provides protection for the electro-optic core from abrasion against rock or coral at cable suspension points during sustained cable strumming.
