Maximum test power of optical power meter
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. The term usually refers to a device. The major types are (Si), (Ge) and (InGaAs). Additionally, these may be used with attenuating elements for high optical power testing, or wavelengt. A typical OPM is linear from about 0 dBm (1 milli Watt) to about -50 dBm (10 nano Watt), although the display range may be larger. Above 0 dBm is considered "high power", and specially adapted units may measure u. Optical Power Meter and accuracy is a contentious issue. The accuracy of most primary reference standards (e.g.,, Length,, etc.) is known to a high accuracy, typically of the orde.
