Ultimately low-complexity optoelectronic feedforward equalization (OE-FFE) scheme is investigated both analytically and experimentally for dispersion-limited high-speed IM/DD PAM4 systems. 6.7% HD-FEC-compliant BERs are achieved for C-band 100Gb/s and 112Gb/s over 50km with 1-tap optical delay line and 19-tap / 31-tap linear FFE only.
