H. Takesue et al., Fast and accurate measurement of WDM components using lightwave synthesised frequency sweeper, ELECTR LETT, 36(12), 2000, pp. 1047-1048
The authors report a method for measuring WDM components that uses a lightw
ave synthesised frequency sweeper. A measurement time of 2s per channel, a
frequency accuracy of +/-20MHz, a resolution of 1GHz and a dynamic range of
50dB were simultaneously achieved.
