Optic Power Meter Wuhan Sunma Technologies Co Ltd - China

price: contact company for price

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


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.
