All-Electronic Flexibly Programmable 864-Gb/s Single-Carrier PDM-64-QAM

Abstract

We generate a 72-GBd single-carrier 64-QAM signal using high-speed digital-to-analog converters. We obtain a record line rate of 864 Gb/s on a single wavelength and demonstrate 5-channel WDM transmission over 400 km of fiber.
