Optical power meter with implementation function
An increasingly common special-purpose OPM, commonly called a "PON Power Meter" is designed to hook into a live PON () 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 cycle of the measured optical signals. It may have a simple pass/ fail display, to facilitate easy use by operators wit.
