Abstract
The present invention provides a performance optimized receiver with a bandwidth adaptive optical filter for high speed long haul wavelength division multiplexed systems, such as 40 Gb/s and 100 Gb/s wavelength division multiplexed systems. The performance optimized receiver includes: a bandwidth and wavelength tunable optical filter, wherein the bandwidth and wavelength tunable optical filter is operable for receiving a plurality of wavelengths associated with a wavelength division multiplexed signal and passing one or more selected wavelengths, and wherein the bandwidth and wavelength tunable optical filter is operable for adjusting the bandwidth of each of the one or more selected wavelengths; and a receiver coupled to the bandwidth and wavelength tunable optical filter. Preferably, the receiver includes one or more of a bit error rate monitoring module and a signal quality monitoring module operable for monitoring the one or more selected wavelengths and providing feedback to the bandwidth and wavelength tunable optical filter such that the bandwidth and wavelength tunable optical filter adaptively adjusts the bandwidth of each of the one or more selected wavelengths.
