The equipment used for out-of-service testing is known as a bit-error-ratio tester, or BERT. :: Minimum Acceptable BER for Telecommunication and Data
An optical power meter is an instrument for measuring the optical power (energy per unit time) in a light beam, such as a laser beam. It typically measures the average power with a relatively low bandwidth.
We can also increase the energy per bit by using higher power transmission, but interference with other systems can limit that option. A lower bit rate increases the energy per bit, but we lose capacity.
An optical power meter (OPM) is a device used to measure the power in an optical signal. The term usually refers to a device used for measuring the average power in fiber optic systems.

With their ability to provide fast and accurate power measurements, these instruments are indispensable tools for optical engineers and technicians.
For the tunable laser calibrations, NIST has developed a measurement system to calibrate optical fiber power meters using either collimated-beam or optical fiber/connector configurations.
For example, if the measured margin is 5 dB, but the overall measurement uncertainty is 2 dB, then in fact the margin may be only 3 dB, which might be unacceptable.
An Optical Power Meter is a device known to feature a calibrated sensor that helps in measuring the display and an amplifier.
