: 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. ©2010 Optical Society of America OCIS: (060.1660) Coherent communications, (060.5060) Phase modulation, (060.2330) Fiber optics communication.
