Abstract
A hybrid cable includes a central strength member, residing in a center of the cable. At least two insulated conductors are abutting the central strength member. One or more buffer tubes are included in the cable, each with at least one optical fiber. One or more filler rods are optionally included in the cable. A shielding layer and jacket surround the elements. In one embodiment, four large insulated conductors and two filler rods abut the central strength member. A first water-blocking tape surrounds the four large insulated conductors, filler rods and central strength member to form an inner core. A concentric core surrounds the central core. The concentric core includes two insulated conductors, plural buffer tubes and a second water-blocking tape surrounding the two insulated conductors and the plural buffer tubes. The shielding layer surrounds the concentric core, and the jacket surrounds the shielding layer. A toning signal carrying medium may also exist outside of the shielding layer.
