Generation of real-valued digital-subcarrier-multiplexed PCS-256QAM is demonstrated using a 120 GSa/s BiCMOS analog multiplexer. A record per-modulation-dimension spectral efficiency of 3 bit/s/Hz is achieved supporting a net data rate of 360 Gbit/s after 10 km IM/DD transmission.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
