How to read the dB value on an optical power meter
Watch the OPM display for a reading in dBm, like -12. 0 dBm and compare it to the expected power level. Fiber Optic Measurement Units: "dB" and "dBm" Whenever tests are performed on fiber optic networks, the results are displayed on a power meter, OLTS or OTDR readout in units of “dB. ” Optical loss is measured in “dB” which is a relative measurement, while absolute optical power is measured in “dBm,”. Instruments measuring in dB can be optical power meters or optical loss test sets (OLTS), with optical power meters usually reading in dBm for power measurements or dB concerning a user-set reference value for loss. The basic process is straightforward: turn the meter on, set it to the correct wavelength, clean your connectors, plug in, and read the. You measure optical power in dBm or insertion loss in dB. Consistent procedures ensure accuracy. The OPM measures optical power, which is the strength of light in a fiber like a flashlight, dim light can signal a problem.
