1.In order to test out the accuracy of the results of optical power meter, cleaning with a cleaning pen is required before use regardless of the instrument or the optical fiber interface;
2.First, detect a section of wire jumper and use 1310nm wavelength for the detection of fiber power meter;
3.One end needs to be connected with a stable light source, and the other end needs to be connected with an optical power meter, thereafter a loss value will appear on optical power meter;
4.Clean the test data by pressing REF button of optical power meter and connect the jump wire with the tested fiber through SC-SC coupler, which makes the test results more accurate. After a few seconds, a stable numerical value will occur on power meter for fiber optic;
5.After the test, the numerical value appeared on optical power meter is the loss value of this optical fiber.
1.In order to test the accuracy of the results of the optical fiber power meter, both the instrument and the optical fiber interface must be cleaned with a cleaning pen before use;
2.Use 1310nm wavelength for the detection of fiber power meter;
3. As there are light sources in the computer room, there is no need to consider the use of stable light sources. Pick a SC interface jumper and insert one end into the chassis light source and connect the other with kpm-25m optical power meter;
4.After the test, the numerical value appeared on optical power meter is the loss value of this optical fiber.
