Abstract
Techniques are disclosed for a broadband service provider to maintain continuity of service in the event that a broadband light source fails in a passive optical network which uses injection-locked transmitters. Generally, a first broadband light source is connected to a passive optical network. Should the first broadband light source fails, it is disconnected from the network, and a second broadband light source is connected to the network.
