Shannon capacity for optical fiber

Webb22 mars 2002 · We obtained analytical expressions for the corrections to the Shannon formula due to fiber nonlinearity. We have shown that, compared to the Shannon limit, the actual channel capacity is substantially suppressed by the photon scattering processes, caused by the fiber nonlinearity.
