Reach Extension of Net-200G/λ IM-DD PAM4 Links to Beyond-100km with Low-complexity Using OE-EQ

We report C-band net-202Gb/s/λ IM-DD PAM4 transmission over single-span up-to-100.9km SSMF using only a single-drive intensity modulator, one PD, one ADC, low-complexity DSP and practical FEC, based on a theory-backed optoelectronic equalization (OE-EQ) technique. © 2024 The Author(s)
