8x250 Gbit/s PAM4 transmission over 1 km single mode fiber with an all -silicon LAN WDM transmitter

We demonstrate 2 Tbit/s (8x250 Gbit/s) and 1.6 Tbit/s (8X200 Gbit/s) 4 -level pulse amplitude modulation (PAM4) transmissions over 1 km and 10 km single mode fibers (SMF) with an all -silicon wavelength division multiplexing transmitter chip. (c) 2022 The Author(s)
