<emphasis role="bold">Description</emphasis> Optical signal to noise ratio (OSNR) is an important figure of merit used in fiber link planning. It is the ratio of signal power to noise power, over a specific spectral bandwidth, at any point in an optical link. Noise power can be defined as any undesirable signal interference. All fiber transmission signals consist of modulated light with some level of background noise. As the noise level increa…
