OverviewWavelength-selective metersSensorsPower measuring rangeCalibration and accuracyExtended sensitivity metersPulse power measurementCommon fiber optic test applications

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 cycle of the measured optical signals. It may have a simple pass/ fail display, to facilitate easy use by operators wit

Coherent Optical Communication

In a coherent optical communication system, the transmitter adopts a direct (or external) approach to modulate the optical carrier amplitude, frequency, or phase.
