Произведена оценка зависимости коэффициента усиления усилителя ВРМБ от мощности накачки, а также связанного с ним процесса возникновения шума спонтанной эмиссии. Показано, что влиянием данного шума при большом коэффициенте усиления можно пренебречь.</p></abstract><trans-abstract xml:lang="en"><p>An analysis of the influence of preamplifier noise with effect of stimulated Brillouin scattering (SBS) in the SNR on receiving the transformed spectrum signals was presented in this paper. The dependence of the SBS amplifier gain of the pump and the spontaneous emission noise was estimated. It is shown that impact of noise in case of high gain is negligible.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>оптический приемник</kwd><kwd>вынужденное рассеивание Мандельштама-Бриллюэна</kwd><kwd>волоконно-оптическая система передачи</kwd></kwd-group><kwd-group xml:lang="en"><kwd>optical receiver</kwd><kwd>stimulated Brillouin scattering</kwd><kwd>fiber-optic transmission system</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Урядов В.Н., Рощупкин Я.В., Бунас В.Ю. и др. // Докл.
