    An optical power meter ( OPM) is a device used to measure the

    power in an optical signal. The term usually refers to a

    device for testing average power in fiber optic systems.

    Other general purpose light power measuring devices are

    usually called radiometers, photometers, laser power meters,

    light meters or lux meters.

    A typical optical power meter consists of a calibrated

    sensor, measuring amplifier and display. The sensor

    primarily consists of a photodiode selected for the

    appropriate range of wavelengths and power levels. On the

    display unit, the measured optical power and set wavelength

    is displayed. Power meters are calibrated using a traceable

    calibration standard such as a NIST standard.

    A traditional optical power meter responds to a broad

    spectrum of light, however the calibration is wavelength

    dependent. 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.

    Optical Loss Test Sets ( OLTS) are available in dedicated

    hand held instruments and platform- based modules to suit

    various network architectures and test requirements. They

    are used to measure optical power and power loss, and

    reflectance and reflected power loss. The products may also

    be used as optical sources or optical power meters, or to

    measure optical return loss or event reflectance.
