Real-time transmission of 240×200-Gb/s signal in S+C+L triple-band WDM without S- or L-band transceivers

Real-time S+C+L triple-band WDM transmission of coherent 200-Gb/s (34-Gbaud DP-16QAM) signals is demonstrated for the first time. With wide-band wavelength converters, 100-nm wavelength range (1504.98–1606.82 nm) transmission over 40 km is realized without a transceiver operating at S- or L-band.
