For wavelength conversion using an optical SSB modulator, a novel technique is proposed for suppression of undesired harmonics. It gives the conventional theoretical limit of signal-to-noise ratio (SNR) by feeding the fundamental and 3rd order harmonic rf-signals. SNR is defined as a ratio of the f0+fm component and the sum of the f0-3fm and f0+5fm components. SNR with 3fm rf-signal is 36.3dB when the conversion efficiency is -6.2dB, while SNR without 3fm rf-signal is 24.1dB.
