7 × 224-Gb/s WDM transmission of reduced-guard-interval CO-OFDM with 16-QAM subcarrier modulation on a 50-GHz grid over 2000 km of ULAF and five ROADM passes

We demonstrate wavelength-division-multiplexed transmission of seven 224-Gb/s reduced-guard-interval CO-OFDM channels with 16-QAM subcarrier modulation on a 50-GHz grid, resulting in a net spectral efficiency of 4 b/s/Hz. Transmission over twenty 100-km ultra-large-area fiber spans and five wavelength-selective-switch passes is achieved.
