We’ve developed PPLN-based wavelength converters for U-band expansion, achieving 3-dB converted gain flatness and 6-dB noise figure for full U-band expansion. A converted 1.2-Tbps/ch. WDM signal is successfully transmitted over 100-km G.654E fiber. We also demonstrate the extensibility beyond U-band up to 1719 nm.
