Single Carrier net 400 Gbit/s IM/DD over 400 m Fiber enabled by Plasmonic Mach-Zehnder Modulator

We demonstrate a 437.1Gbit/s IM/DD link by employing a 178GBd PAM8 signal encoded by a plasmonic MZM. Symbol rates of up to 256GBd and transmission over 400m while maintaining net-rates of >400Gbit/s are successfully demonstrated.
