The use of the optical power meter

The use of optical power meter first need to have several conditions: a glowing light source (light source device mouth or transmitted light light path);Test fiber (must be connected to the light source and optical power meter connector, connector does not match the words need to the corresponding converter);Droop (if a high optical power);Optical power meter (electricity).In uncertain light power (high), first the droop in light or optical power meter, one end.Then light source and optical power meter with a fibre-optic link, and open the optical power meter, press “enter” symbol, adjust the corresponding wavelength shows the value plus droop is light power, if measured optical power is not high, suggested  that the droop take next to test again.Used to measure the absolute optical power or by a fiber optical power relative loss.In the optical fiber system, optical power measurement is the most basic, much like the multimeter electronics.In the optical fiber measurement, optical power meter is a commonly used table heavy load.By measuring the transmitting terminal machine or the absolute power of the optical network, an optical power meter can evaluate the performance of the light end equipment.Combinations of light power meter and stability of light source, is able to measure the connection loss, continuity test, and help to evaluate quality of fiber optic link transmission.
