Abstract

A new method for the semi-analytical estimation of the BER of digital optical systems is presented. It is based on system simulation and accurately considers the performance degradation caused by waveform distortion. The method profits from the simplicity of Gaussian approximation for noise statistics, though explicitly accounting for ISI effects in noise during the BER estimation. Optically preamplified and APD receivers are considered, for which signal-dependent noise components are dominant. The system parameters influence on receiver sensitivity is studied
