Calibration of wavelength/optical frequency measurement instruments - Optical spectrum analyzers Ingestion-build-86103 Externally threaded fastener manufacturers1 Scope This part of IEC 62129 specifies procedures for calibrating an optical spectrum analyzer that is developed for use in fibre optic communications and designed to measure the power distribution of an optical spectrum. It does not apply to an optical wavelength meter that measures only centre wavelengths, a Fabry Perot interferometer or a monochromator that has no display unit.
