Claim:
A system comprising: a hub; at least one node that is located remotely from the hub; wherein the hub is coupled to the at least one node by a first fiber path and a second fiber path, the first fiber path comprising an uplink fiber and a downlink fiber, and the second fiber path comprising an uplink fiber and a downlink fiber; wherein the at least one node is coupled to the downlink fiber of the first fiber path and the downlink fiber of the second fiber path via an optical combiner; wherein the at least one node is further coupled to the uplink fiber of the first fiber path and the uplink fiber of the second fiber path via an optical splitter; wherein the at least one node further monitors a signal quality of a downlink optical signal and communicates to the hub information indicative of the signal quality; and wherein the hub switches communications between the hub and the at least one node from the first fiber path to the second fiber path based on the information indicative of the signal quality.
