An electromagnetic sensor cable includes at least one strength member configured to be coupled to a vessel for towing in a body of water and extending along the length of the cable. A jacket covers the strength member and extends along the length of the cable. At least one electrode mounting sleeve is disposed along the jacket and is coupled at its longitudinal ends to one end of a segment of the jacket. The longitudinal ends of the sleeve are configured to mate with a corresponding end of the jacket segment. The sleeve includes a passage therethrough for the at least one strength member. The sleeve includes a mounting surface for a fiber electrode material thereon disposed between the longitudinal ends of the sleeve. At least one electrical contact surface is disposed on the mounting surface. Electrically conductive fiber electrode material is disposed on the mounting surface and is in electrical contact with the electrical contact surface.
