Abstract

A vehicle communication system includes a fiber optic assembly and a cable assembly. The fiber optic assembly is configured to couple a controller to a plurality of vehicle components to enable communication of information between the controller and the vehicle components. The cable assembly extends from a vehicle power supply, with each of the vehicle components electrically coupling to a different respective location along the cable assembly to receive power from the vehicle power supply via the cable assembly. A portion of the fiber optic assembly and a portion of the cable assembly are mechanically coupled to each other such that the portion of the fiber optic assembly and the portion of the cable assembly collectively extend along the vehicle.
