A novel technology for simultaneous WDM signal monitoring is presented based on ultrafast field sampling. Its flexibility regarding channel allocation and/or channel bandwidth is unique and attractive, as is its ultrafast nature. Two-and four-channel WDM signals, with the total bandwidth of 800 GHz, are successfully discriminated and observed with the proposed scheme.
