We study experimentally and theoretically the limits of multichannel parametric wavelength conversion imposed by pump depletion in periodically poled LiNbO<sub>3</sub> waveguides. As many as 55 channels with 6 dBm of power each can be converted simultaneously with less than a 10<sup>−9</sup> error rate by use of 20 dBm of pump power.
