Fiber optical power meter 20mw 20km FO Tester Visual Fault Locator
An optical power meter (OPM) is a device used measure the power in an optical signal.
The term usually refers to a device for testing average power in fiber optic systems.
This is not normally an issue, since the test wavelength is usually known,
however it has a couple of drawbacks.
Firstly, the user must set the meter to the correct test wavelength,
and secondly if there are other spurious wavelengths present, then wrong readings will result.
Sometimes optical power meters are combined with a different test function
such as an Optical Light Source (OLS) or Visual Fault Locator (VFL),
or may be a sub-system in a much larger instrument.
When combined with a light source, the instrument is usually called an Optical Loss Test Set.
