Frequency Domain Joint Monitoring of DGD and PDL in Optical Coherent Communication Systems Using CAZAC Sequences
We propose a CAZAC sequences-based frequency-domain joint DGD and PDL estimation scheme, achieving stable errors of <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$<0.3$</tex> ps and <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$<0.3 \text{dB}$</tex>, respectively, and can be easily integrated into existing DSP architecture for on service monitoring.
