Net 582-Gb/s C-band and 4$\times$526-Gb/s O-band IMDD Transmis-sion Using Ultra-broadband InP-DHBT-based Electrical Mixer

Abstract

We successfully transmitted a net 582-Gb/s probabilistically shaped PAM12 C-band signal over 11-km dispersion-shifted fibre and net 4$\times$526-Gb/s uniform PAM8 O-band signals over 2-km four-core fibre using a single-carrier 216-GBd IMDD system based on a 150-GHz bandwidth InP-DHBT electrical mixer and a thin-film lithium-niobate modulator.
