Unified Training-Sequence Joint Carrier Recovery for 200 Gbps FTN Coherent PON Upstream

To meet the 200 Gb/s per-wavelength capacity target of next-generation passive optical networks (PON), faster-than-Nyquist (FTN) signaling compresses the signal spectrum and relaxes the optoelectronic bandwidth requirement at the optical network unit (ONU), while 16-ary quadrature amplitude modulati...
