Summary :

We demonstrate a simple BER monitoring method for WDM signals. Newly developed 32-channel wavelength selector based on thermo-optic switch and AWG is used. The BER of each channel is estimated from opened eye-diagrams obtained by asynchronous sampling. Good BER monitoring performance is confirmed.
