Phase-Coherent DSP over Space and Wavelength using Synchronized Optical Frequency Combs for Short-Reach Networks
We demonstrate shared DSP over space and wavelength for short-reach networks using seed-synchronized optical frequency combs. Using just 6 reference channels, carrier phase recovery of 3(cores)×158 × 24.5-GBaud PDM-64QAM C-band channels is demonstrated with > 40-Tb/s/core over 14 . 3-km MCF without dispersion or frequency-offset compensation.
