Principle of Optical Power Meter Measurement with Small Square Head
An optical power meter (OPM) measures the strength of light signals in fiber optic systems. At its heart, an OPM uses a photodiode. It details the main components, including sensor heads and display units, and explains the two primary sensor technologies: robust thermal sensors for high powers and. Semiconductor photodiodes are ideal for making measurements of low-level light due to their high sensitivity and low noise characteristics. Most photodiode manufacturers specifically design their diodes to be used in either the photoconductive (reverse biased) or the photovoltaic (no bias) mode. Optical power meters are a key element in the optimization and maintenance of such optical networks and of their components.
