800G: Coherent versus PAM4 Optical Transceivers Inside Data Centers

400ZR pluggable coherent transceivers for up to 80-120km distance will emerge in 2020~2021 time frame, and their cost is expected to be comparable to today’s 80km 100G pluggable PAM4 transceivers, which results in essentially 3~4x cost per bit reduction.
