25Gbps two-dimensional trellis coded PAM4 TDM-PON transmission based on 10G optics

We demonstrate an alternative approach to 25Gbps 2D TCM PAM4 for TDM-PON with 10GHz optics, which employs M-algorithm at its decoder. Compared to PAM4, 2D TCM PAM4 brings the power budget up by ∼3dB with low complexity.
