Abstract
An optical transponder, system, method, and program wherein the transponder monitors for at least one of a failure or an alarm signal. In response to detecting a failure or alarm signal (communication), the transponder performs at least one of a predetermined action and propagating an alarm communication to a network, based on a configuration property. The transponder can have a configuration property specifying a predetermined action for shutting off a laser if an alarm signal indicating a network failure is detected. As an example, some transponders can be configured to either provide an alarm communication, and/or shut off a laser, depending upon which communication interface detects a network failure or receives an alarm signal. Also, other transponders can be configured to propagate existing alarm communications, without generating new alarm communications or shutting off lasers. In this manner, the number of alarm signals and laser shut offs can be reduced when a network failure is propagated through the network.
