Abstract: An optical wavelength calibrator is configured to be used on premises with instrumentation such as an optical spectrum analyzer. The on-premises calibrator includes both a fixed wavelength source and a tunable wavelength source, with a variable optical attenuator controlling the power level of a calibration beam provided as an output. A controller within the on-premises calibrator is used to generate the control signals for the various components in response to received external commands, typically via from an external GUI of the user's computer system. The controller is used in combination with the tunable wavelength source to provide a series of output calibration signals at different wavelengths, providing the ability to performance calibration across a desired spectral region and not just a single wavelength. The on-premises calibrator maintains real-time wavelength stability of the instrument to minimize down time when compared off-site extensive re-calibration services.
