Fiber Optic Light Meter Readings

Fiber optic power meter test procedure.

Fiber optic light meter readings.

At the other end of the cable the power meter reads that light or optical power level and determines. 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. Ofstp 14 for the installed multimode cable plant ofstp 7 for the installed singlemode cable plant as of 2011 ofstp 14 has been replaced by an international standard that as of mid 2011 is very controversial. The term usually refers to a device for testing average power in fiber optic systems.

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. 4 5 out of 5 stars 33. In addition to a power meter you need a test source. An optical power meter opm is a device used to measure the power in an optical signal.

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 cable loss insertion loss with light source and power meter standard. Get it as soon as wed sep 16. Most fiber optic power meters are available with a choice of 3 different detectors silicon si germanium ge or indium gallium arsenide ingaas.

Optical power meters typically use semiconductor detectors since they are sensitive to light in the wavelengths and power levels common to fiber optics. The light source sends a wavelength of light down the fiber. 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. This test works just like a fiber optic communications system.

Purchase an insertion loss testing set with an optical source and meter. The test source is used as a transmitter and a power meter is used as a receiver. Optical loss tested with a light source power meter and two reference cables is the most common measurement in fiber optics. To perform an insertion loss test buy a testing kit from a fiber optic or it company.

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. Optical power in fiber optics is similar to the heating power of a light bulb just at much lower power levels.
