Transmission of a 448-Gb/s Reduced-Guard-Interval CO-OFDM Signal with a 60-GHz Optical Bandwidth over 2000 km of ULAF and Five 80-GHz-Grid ROADMs

Abstract
We demonstrate the generation and detection of a novel reduced-guard-interval CO-OFDM signal at 448 Gb/s, occupying 60-GHz optical bandwidth. We transmit this signal over 2000 km of ULAF with five 80-GHz-grid WSS-based ROADM passes.
