We present a new simple analysis - including the effect of spontaneous emission - of the (dynamic) influence of SBS on the detected receiver eye diagram. It applies in principle for general types of modulation formats such as the digital formats of ASK, FSK, and PSK. The analysis is formulated for a determination of the signal power depletion and ISI caused by the combined effect of fiber dispersion, fiber attenuation and non-linear fiber effects such as the effect of SPM and SBS. The analysis allows a quantification of the dithering influence on the SBS threshold. Representative numerical examples are presented for two single-channel On/OFF modulated 10 Gb/s systems utilizing Franz-Keldysh and Mach-Zehnder type modulators.
