Abstract:
1. A remote node comprising: an interface by which an uplink radio frequency signal is received at the remote node and from which a downlink radio frequency is output; an optical transceiver communicatively coupled to the interface to output an uplink optical signal derived from the uplink radio frequency signal and to receive a downlink optical signal; a splitter to couple the optical transceiver to a primary uplink optical communication medium and a second uplink optical communication medium in order to communicate the uplink optical signal on the primary uplink optical communication medium and the second uplink optical communication medium; and a combiner to couple the optical transceiver to a primary downlink optical communication medium and a second downlink optical communication medium, wherein the combiner combines any optical signal received on the primary downlink optical communication medium and any optical signal received on the second downlink optical communication medium to output the downlink optical signal; wherein the optical transceiver outputs a downlink electrical signal derived from the downlink optical signal, wherein the downlink radio frequency signal is derived from the downlink electrical signal; a manager monitoring a signal quality of the downlink optical signal, wherein the manager communicates to an upstream device for switching the downlink optical signal and the upstream optical signal based on the signal quality.
