Does an optical power meter need to be calibrated periodically
Commercial power meters are calibrated using working standards that are periodically verified against reference standards, which are regularly calibrated by a national metrology institute (NIST in the case of EXFO). EXFO can help save both time and costs with an automated calibration test system that is designed for the verification of power meters, attenuators, sources and optical time-domain reflectometers (OTDRs). This application note demystifies how EXFO's IQS-12002 Optical Calibration System can guide. These measurements are accomplished using either collimated-beam or connectorized-fiber configurations at the three principle wavelength regions used by the fiber telecommunication industry: 850, 1310. If we find a performance problem with the received instrument, we will let you know.
