The basic process is straightforward: turn the meter on, set it to the correct wavelength, clean your connectors, plug in, and read the display. An optical power meter measures the strength of light traveling through a fiber optic cable, giving you a reading in dBm (decibels relative to one milliwatt). " Optical loss is measured in "dB" which is a relative measurement, while absolute optical power is measured in "dBm,".

A traditional optical power meter responds to a broad spectrum of light, however, the calibration is wavelength dependent.

A class of "high power" meters has some type of optical attenuating element in front of the detector, typically allowing about a 20 dB increase in maximum power reading. OverviewAn optical power meter (OPM) is a device used to measure the power in an signal.

In this video, I explain how to calibrate optical power meters including Comptyco OPM, Chinese non-branded OPM, and KING-60S OPM using simple field-level methods. moreEXFO 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. Optical power meters are designed to measure optical power in a specified wavelength range as accurately as possible.
