When an optical signal is amplified by an optical amplifier, its OSNR decreases, which limits the number of amplifiers that can be used in a network.
Optical signal-to-noise ratio (OSNR) is used to quantify the degree of optical noise interference on optical signals. It is the ratio of service signal power to noise power within a valid bandwidth.
The scale fidelity of the instrument (that is, its ability to measure power correctly at different power levels) contributes to the OSNR measurement uncertainty as the peak power and the noise level are
