An armored optical cable and process of manufacturing is described. The armored optical cable exhibits minimal inelastic elongation in response to tension at elevated temperatures and is capable of withstanding harsh ambient conditions. The armored optical cable is fabricated in a unitary operation with a central bundle of one handedness surrounded by at least one outer armor layer of opposite handedness substantially torque balanced to the handedness of the central bundle.

An armored optical cable suitable for use in an environment which subjects said cable to repeated longitudinal elongation and relaxation forces, said cable comprising: a substantially non-deformable central core element; at least six substantially solid elements would helically around said central element in a given handedness; at least twice the number of said at least six elements of inner armor wires wound around and contacting said at least six elements of the same handedness in a unilay helical configuration, said at least six elements and said inner armor wires being fabricated around said central core element at the same time wherein the elements and the wires of the same handedness and the central core element form a central bundle, said central bundle containing at least one jacketed optical fiber; and a plurality of outer armor wires contacting said inner armor wires, said outer armor wires wound in an opposite helical handedness to the handedness of said inner armor wires such that the torques exerted by said inner armor wires and said outer armor wires are substantially balanced.
