The OSNR is the ratio between the signal power and the noise power in a given bandwidth. Most commonly a reference bandwidth of 0.1 nm is used. This bandwidth is independent of the modulation format, the frequency and the receiver. For instance an OSNR of 20 dB/0.1 nm could be given, even the signal of 40 … See more Signal-to-noise ratio (SNR or S/N) is a measure used in science and engineering that compares the level of a desired signal to the level of background noise. SNR is defined as the ratio of signal power to the noise power, … See more Amplitude modulation Channel signal-to-noise ratio is given by $${\displaystyle \mathrm {(SNR)_{C,AM}} ={\frac {A_{C}^{2}(1+k_{a}^{2}P)}{2WN_{0}}}}$$ where W is the bandwidth and Output signal-to … See more When a measurement is digitized, the number of bits used to represent the measurement determines the maximum possible signal-to … See more Optical signals have a carrier frequency (about 200 THz and more) that is much higher than the modulation frequency.
