1. An electrical cable comprising:
- an outer cable jacket extending a length and having an internal passageway that extends along the length of the outer cable jacket;
twisted pairs of insulated electrical conductors extending within the internal passageway along the length of the outer cable jacket, each twisted pair comprising two insulated electrical conductors twisted together in a helical manner; and
at least two optical fibers extending within the internal passageway along the length of the outer cable jacket, wherein the optical fibers are independently held within the internal passageway of the outer cable jacket relative to each other; and
an inner cable jacket extending within the internal passageway of the outer cable jacket, the inner cable jacket surrounding the twisted pairs, the optical fibers extending between the inner and outer jackets.

Abstract
An electrical cable includes a cable jacket extending a length and having an internal passageway that extends along the length of the cable jacket. Twisted pairs of insulated electrical conductors extend within the internal passageway along the length of the cable jacket. Each twisted pair includes two insulated conductors twisted together in a helical manner. At least two optical fibers extend within the internal passageway along the length of the cable jacket. The optical fibers are independently held within the internal passageway of the cable jacket relative to each other.
