Abstract
Abstract A method and apparatus for providing a talk path in a longitudinal cavity of an enhanced crush, impact, and cut-through resistant communications cable. The talk path is especially suited for a fiber optic communications cable. The cable jacket is formed of a deformable material having a plurality of longitudinal cavities spaced about the cable core. A longitudinal cavity may contain a copper pair or optical fiber to serve as a talk path during servicing of the cable. The talk path may be readily accessed by a service technician without exposing the inner core or the communications cable.
