Can an optical power meter test breakpoints
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. 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.
