1. An active cable node circuit associated with a hybrid fiber coax network, comprising:
an uplink transceiver circuit configured to couple to an aggregation node circuit over a first coax cable link comprising coaxial cables and configured to receive a set of downstream data signals from the aggregation node circuit over the first coax cable link, the set of downstream data signals having been transmitted toward the aggregation node circuit as one or more data packets over a fiber link; and
one or more access transceiver circuits configured to provide the set of downstream data signals received at the uplink transceiver circuit or a processed version thereof, to one or more access circuits, wherein each of the one or more access transceiver circuits is configured to couple to the uplink transceiver circuit at a first end, and wherein each of the one or more access transceiver circuits is configured to couple to a set of access circuits of the one or more access circuits at a second, different end, and
wherein each of the one or more access transceiver circuits is configured to couple to the set of access circuits over a second coax cable link comprising coaxial cables.
