Abstract
A hybrid cable for distributing communications signals and three-phase moderate-voltage alternating current, and a distribution method and network using the hybrid cable. The cable includes a hollow conduit, an optical fiber pulled through the conduit and housed within the conduit, power conductors disposed around the conduit, and a sheath which provides both structural protection and dielectric properties encasing the power conductors.

14. A hybrid cable for providing optical signals and power to a remote location, comprising:
-
a hollow plastic conduit adapted to have an optical fiber pulled therethrough and housed therein after said cable is deployed; a plurality of insulated power conductors disposed helically around the plastic conduit; a metallic sheath encasing the power conductors, so that a watertight assembly is formed; and a dielectric outer jacket covering the metallic sheath.

15. A method of distributing power and optical signals to a remote location, comprising:
-
(1) installing a cable originating at a central location and terminating at the remote location, the cable comprising a hollow conduit, a plurality of power conductors disposed around the hollow conduit, a sheath encasing the power conductors, said sheath having one or more layers for providing both structural strength and dielectric properties; (2) pulling an optical fiber through the hollow conduit from the central location to the remote location, so that the cable transmits optical signals on the optical fiber and three-phase power on the power conductors; (3) isolating the power from the optical signals; and (4) converting at the remote location the power transmitted by the cable for use in powering an active component in the network.

16. A network for distributing power and optical signals to a remote location, comprising:
-
a centrally located three-phase alternating current power supply; a hybrid cable for providing optical signals and for transmitting power from said centrally located power supply to the remote location, said hybrid cable comprising a hollow conduit adapted to have an optical fiber pulled therethrough and housed therein, a plurality of power conductors disposed around the hollow conduit, a sheath encasing the power conductors, said sheath having one or more layers for providing both structural protection and dielectric properties; a terminal located at the remote location for isolating the power from the optical signals; and a power supply in communication with the terminal, said power supply receiving the power transmitted by said hybrid cable for use in powering an active component in the network. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23)
