Abstract: A system for providing data communications over coaxial cables. The system may include a splitter configured to receive a first signal of a first signal type from a first transmission medium and to split the first signal into a first and second signal parts. The system may also include an adapter coupled to the splitter and configured to receive the first signal part and a second signal of a second signal type that is configured for transmission on a second transmission medium. The adapter may be further configured to combine and to output the first signal part and the second signal on a first cable of the first transmission medium. The system may also include a filter coupled between the splitter and the adapter and configured to prevent the second signal type from reaching the splitter.
