Ultra-Wideband optical transmission system applying optical wavelength conversion technology

We have demonstrated real-time S+C+L triple-band WDM transmission of coherent 200-Gb/s (34-Gbaud DP-16QAM) signals by employing all-optical wavelength converters. 100-nm wavelength range (1504.98–1606.82 nm) transmission over 40 km is realized by using only transceivers operating at C-band.
