摘要： Higher rate channels (e.g., 40 Giga bits or greater) have large bandwidths and are susceptible to inter-channel crosstalk. Optical tunable filters may be used to overcome crosstalk. Tunable filters do not maintain their central wavelength over a long duration or a wide temperature range. An example embodiment of the present invention relates to shaping a channel signal within a dense wavelength division multiplexing signal and may employ a tunable filter and input and output optical power detectors to measure a modulated source channel signal at an input of the tunable filter and a filtered modulated source channel signal at an output of the tunable filter. A controller is configured to adjust a center wavelength of the tunable filter as a function of a difference between measurements of optical power by the optical power detectors. Adjusting the center wavelength shapes the channel signal and overcomes undesired effects for higher rate channels.

摘要： 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.
