Abstract

A communication network includes a first electrical cable, a home network translation device, and a first termination device. The home network translation device is communicatively coupled between an optical cable and the first electrical cable, and the home network translation device is configured to translate data between an optical protocol on the optical cable and a home networking protocol on the first electrical cable. The first termination device is communicatively coupled to the first electrical cable and is configured to translate data between the home networking protocol on the first electrical cable and an additional protocol on an additional communication medium communicatively coupled to the first termination device.

First claim

What is claimed is:

1. A communication network, comprising:
a first coaxial electrical cable;
a home network translation device communicatively coupled between an optical cable and the first coaxial electrical cable, the home network translation device configured to translate data between an optical protocol on the optical cable and a home networking protocol on the first coaxial electrical cable;
a first termination device communicatively coupled to the first coaxial electrical cable and configured to translate data between the home networking protocol on the first coaxial electrical cable and an additional protocol on an additional communication medium communicatively coupled to the first termination device;
a second termination device communicatively coupled to the first coaxial electrical cable and configured to translate data between the home networking protocol on the first coaxial electrical cable and a second additional protocol on a second additional communication medium communicatively coupled to the second termination device; and
a transformer configured to serve as a splitter by communicatively coupling each of the first and second termination devices to the first coaxial electrical cable, such that home networking signals can flow between the first and second termination devices via the transformer.

2. The network of claim 1 , wherein the first termination device is located within a customer premises, and the home network translation device is located outside of the customer premises.

3. The network of claim 2 , further comprising a power inserter located within the customer premises and configured to electrically power the home network translation device via the first coaxial electrical cable.

4. The network of claim 3 , wherein the power inserter includes power supply circuitry and an inductor having a tapered shape, the inductor electrically interfacing the power supply circuitry with the first coaxial electrical cable.

5. The network of claim 3 , wherein the home network translation device comprises an inductor having a tapered shape electrically coupled between the first coaxial electrical cable and a power supply of the home network translation device, to couple electrical power from the first coaxial electrical cable to the power supply of the home network translation device.

6. The network of claim 1 , wherein:
the home networking protocol is one of a Multi-Media over Coax (MoCA) protocol and a HomePNA (G.hn) protocol; and
the optical protocol is one of an Ethernet passive optical network (EPON) protocol, a radio frequency of over glass (RFOG) protocol, and a Gigabit-capable passive optical network (GPON) protocol.

7. The network of claim 1 , wherein the home network translation device is configured to transmit data upstream over the optical cable in response to a grant received from a cable modem termination system (CMTS) communicatively coupled to the optical cable.

8. The network of claim 1 , wherein the home network translation device is further configured to transmit a broadcast signal over the first coaxial electrical cable while communicating with the first termination device via the first coaxial electrical cable using the home networking protocol.

9. The network of claim 1 , wherein the home network translation device is configured to serve as a network host to the first termination device.
