Calibration of wavelength/optical frequency measurement instruments - Optical spectrum analyzers Ingestion-build-137917 warning devicesWhat is BS EN 62129 1 Optical spectrum analyzers about? BS EN 62129 1 is a safety standard on the calibration of wavelength optical frequency measurement instruments. BS EN 62129 1 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. BS EN 62129 1 describes a set of operations that establish, under specified
