Summary: 
We present the first demonstration of multiple-stage wavelength conversion using cascaded LiNbO3 Mach-Zehnder SSB modulators. Wavelength is accurately shifted by 18 GHz at each stage. 72 GHz frequency shift with the relative intensity noise (RIN) value of -144.5 dB/Hz is achieved by four stages. The achieved equivalent noise figure is 7.5 dB.
