ABSTRACT:
An apparatus for measuring an OSNR for a communication channel in a WDM optical communications system includes a signal control unit, a receiving unit, and a measuring unit. The signal control unit controls spectral width reduction for an optical signal sent through a target channel. The receiving unit receives spectral data measured from the optical signal received by the target channel under control of the control unit. The measuring unit, based on the spectral data received by the receiving unit, measures the OSNR of the target channel.
