How is power measured in fiber optics
• Measuring the absolute power in a fiber optic signal. For this application, the power meter needs to be properly calibrated at the wavelength being tested, and set to this wavelength. • Measuring the optical loss in a fiber, in combination with a suitable stable light source. Since this is a relative test, accurate calibration is not a particular requirement, unless two or more meters are being used due to distance issues. If a more complex two-way loss test is performed, then power met… WebMeasuring Power Measurements of optical power are expressed in units of dBm. The “m” in dBm refers to the reference power which is 1 milliwatt. Thus a source with a power level of 0 dBm has a power of 1 milliwatt.
