Fiber Optic Light Meter Readings

To test the end to end performance of a fiber optic system two pieces of handheld equipment are needed an opm tester and a light source.

Fiber optic light meter readings.

Other general purpose light power measuring devices are usually called radiometers photometers laser power meters can be photodiode sensors or thermopile laser sensors light meters or lux meters. At the other end of the cable the power meter reads that light or optical power level and determines. An optical power meter opm is a device used to measure the power in an optical signal. This kit includes an optical source which fires a signal into the cable and an optical meter which reads the signal at the other end.

The test source should match the type fiber generally led for mm or laser for sm and wavelength 850 1300 1550 nm that will be used on the fiber optic cable you are testing. In addition to a power meter you need a test source. Fiber optic power meter test procedure. Purchase an insertion loss testing set with an optical source and meter.

Opm optical power meter digital power factor meter 70 6dbm with 6 optic wave length portable fiber optic cable tester with fc converter for fc sc st 30mw 30km visual fault locator msdada red light fiber optic cable tester meter cable test equipment fit for 2 5 mm universal connector for catv telecommunications engineering maintenance. Optical power in fiber optics is similar to the heating power of a light bulb just at much lower power levels. Fotp 171 for cable assemblies standard. 4 5 out of 5 stars 33.

The light source sends a wavelength of light down the fiber. The test source is used as a transmitter and a power meter is used as a receiver. Fiber optic cable loss insertion loss with light source and power meter standard. Optical power meters typically use semiconductor detectors since they are sensitive to light in the wavelengths and power levels common to fiber optics.

Most fiber optic power meters are available with a choice of 3 different detectors silicon si germanium ge or indium gallium arsenide ingaas. To perform an insertion loss test buy a testing kit from a fiber optic or it company. Get it as soon as wed sep 16. This test works just like a fiber optic communications system.

While a light bulb may put out 100 watts most fiber optic sources are in the milliwatt range 0 001 watts so you won t feel the power coming out of a fiber and it s generally not harmful. The term usually refers to a device for testing average power in fiber optic systems.
