The Fundamentals Of Optical Power Measurement

Optical power measurement yields a positive number

Although OPM testers measure a negative number for loss, it is conventionally said as a positive number. For example, if the optical power meter reading is “-3. Optical loss is measured in “dB” which is a relative measurement, while absolute optical power is measured in “dBm,” which is dB relative to 1mw optical power Loss is a negative number (like –3. 2 dB) while power measurements can be either positive (greater than the reference) or negative (less than. While optical power meters are the primary power measurement instrument, optical loss test sets (OLTSs) and optical time domain reflectometers (OTDRs) also measure power in testing loss. It can be a focusing power, also called dioptric power, for example of a lens or microscope objective. 0 dB" signifies a loss of 3.
