Abstract
A hybrid data communications cable includes optical fibers and insulated electrical conductors. The cable includes an elongated filler member having a central portion, walls extending radially from the central portion and a conduit running the length of the filler member. The optical fibers are enclosed within the conduit, and at least one insulated electrical conductor is separated from another insulated electrical conductor by one or more walls of the filler member. The cable further includes a jacket that encloses the filler member and the insulated electrical conductors.
