    Selection of Optical Power Meter for Low-Voltage Electrical Construction

    An increasingly common special-purpose OPM, commonly called a "PON Power Meter" is designed to hook into a live PON (Passive Optical Network) circuit, and simultaneously test the optical power in different directions and wavelengths. This unit is essentially a triple power meter, with a collection of wavelength filters and optical couplers. Proper calibration is complicated by the varying duty cycl. OverviewAn optical power meter (OPM) is a device used to measure the power in an signal. The term usually refers to a device for testing average power in systems. Other general purpose light power measuring. 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.
