Abstract
An optical signal measurement system provides a tunable optical filter. An unknown optical signal is scanned through the tunable optical filter. The wavelength and chromatic dispersion values of the unknown optical signal scanned through the tunable optical filter are measured by operating the tunable optical filter in a scanning mode for at least one of OSA and PMD measurements, and in a stepping mode for CD measurements. The wavelength and the dispersion values in the unknown optical signal are specified.
