Optical power meters can measure the power of both single-mode and multimode fibers. In single-mode fiber, the rays travel down its entire length without any internal reflection at all. In multimode fiber, multiple rays enter at different angles and possibly have different wavelengths. An optical power meter (OPM) is a device used to measure the power in an optical signal. The term usually refers to a device for testing average power in fiber optic systems. The term "optical power meter" may sound generic, but in popular usage, it specifically implies a fiber optic power meter. For light power measurements outside the field of. Optical loss is measured in “dB” which is a relative measurement, while absolute optical power is measured in “dBm,” which is dB relative to 1mw optical power Loss is a negative number (like –3.
