Fiber optic power meter test procedure.

Attenuation power test shall be 1310 nm and 1550 nm. If testing a laser use of an apc connector plugged into the power meter will reduce optical reflections and so generally improve measurement accuracy. An optical power meter opm also called optical power meter tester or opm tester is a testing instrument working to accurately measure the power of fiber optic equipment or the power of an optical signal passed through the fiber cable. Made up of a calibrated sensor that measures an amplifier circuit and a display the opm tester can be used for installation debugging and maintenance of.

If the connector s on the cables to test are plug and jack type and or are not compatible to the optical power meter for testing and or reference you cannot test single ended. 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. The fiber optic cable will be tested at 1550 nm for single mode as per project specification ve 539014 para 7 5 1 5 and saes t 634. Use the fiber optic cable plant or foa 1 page standard foa1 method with a 2 or 3 cable reference as appropriate.
