Abstract

Various embodiments of the present disclosure are directed toward a signal-communicating apparatus and methods of use that include a signal-communication path for communicating between remotely situated compartments in a vehicle with the path defined by a flexible cable. A signal interconnecting circuit is provided that includes a first interface circuit that couples optical signals to a first portion of the cable, and another interface circuit that couples electrical signals to another portion of the cable. The signal interconnecting circuit includes a signal-path connector that mechanically secures and communicatively couples the portions together. Additionally, a data communication circuit is provided to receive data carried by the signal-communication path via the flexible cable and the signal interconnecting circuit.
