摘要
Methods and systems for in-band OSNR monitoring include a tunable optical filter to scan a passband of a desired optical channel. The optical power over the passband is measured and digitized to power waveform data. The power waveform data is processed with a digital signal processor to calculate OSNR. Additionally, various implementations accommodate dual polarization modulation formats using a parallel architecture and an alternating sequential architecture.
