Выполнено исследование распространения сигнала в волоконной линии связи с сонаправленной накачкой. Несмотря на невозможность переноса шумов из накачки в сигнал в результате вынужденного комбинационного рассеяния (ВКР), в натурном эксперименте наблюдается деградация сигнала уже при небольших длинах распространения (порядка 5-10 км). Для исследования причин деградации сигнала построена численная модель на основе обобщенного нелинейного уравнения Шрёдингера, учитывающая дисперсию высших порядков, керровскую нелинейность и запаздывающий рамановский отклик среды. Также используется более реалистичная модель многомодового источника накачки. В результате проведенного численного анализа продемонстрировано, что в определенных условиях не только ВКР, но и четырехволновое смешение может инициировать в линиях связи процесс переноса шумов из накачки в сигнал. It is well known that any real transmission link introduces distortions into the signal that can be either recoverable or not fully removable. The sources of such unremovable distortions leading to the loss of information are double Rayleigh scattering, amplified spontaneous emission, RIN (Relative Intensity Noise) transfer and nonlinear interactions such as four-wave mixing. In this paper we perform numerical investigation of signal propagation and RIN transfer in optical communication link with co-propagating pump. Despite the impossibility of intensity noise transfer from pump to signal due to stimulated Raman scattering (SRS), in the experiment signal degradation is observed even at small propagation lengths of 5-10 km. To find the origin of signal degradation, a numerical model is proposed based on the generalized nonlinear Schr¨odinger equation. The model takes into account the higher-order dispersion, Kerr nonlinearity, and the delayed Raman response of the medium. A more realistic model of the multimode pumping source is also employed. It is worth noting, that the most common analytical and numerical models, describing RIN transfer from pump to signal, are based on balance equations and neglects influence of dispersive and nonlinear effects. As a result of the numerical analysis, it was demonstrated that not only SRS but also four-wave mixing can initiate the process of noise transfer from pump to signal in the communication links.
