Abstract
In an optical fiber communication system, for signal monitoring a transparent optical network (all-optical networks), i.e. a system without digital intermediate regeneration, the bit error probability (BEP) is calculated by dismodulating and sampling the signal and generating an amplitude histogram. This histogram serves mainly for modeling the signal distortions. A family of amplitudes that represent the average of a noise-infested sub-signal is determined from the histogram for each status of the signal (logical '0' or '1'). The variance of the individual noise signal overlaid on every amplitude value is calculated from the parameters of the receiver as well as from the optical signal-to-noise ratio (OSNR). The bit error probability is calculated with adequate precision from these parameters.
