Abstract
A method for wavelength conversion comprising receiving an input optical signal with a first wavelength, converting the input optical signal to a plurality of input analog signals, generating a plurality of digital signals based on the input analog signals, compensating for waveform distortions by at least filtering one or more of the digital signals to generate one or more compensated digital signals, converting the compensated digital signals to output analog signals via digital-to-analog (DA) conversion, generating an output optical signal with a second wavelength different from the first wavelength based on the output analog signals, and transmitting the output optical signal.
