Calculation of the effect of nonlinear effects in DWDM systems on the energy characteristics of a signal

Abstract
Nowadays DWDM (Dense Wavelength - Division Multiplexing) technology that allows increasing manyfold bandwidth capability of existing telecommunication systems and combining different types of telecommunication technologies into a single information infrastructure is being implemented actively. The main component of the DWDM system is an optical fibre. Various nonlinear effects that result in cross-interference between the optical channels and in the power reduction of the transmitted signal are created in the optical medium of signal transmissions in combination with other features of the DWDM technology. This results in lower transmission quality in the DWDM telecommunication system. Most works devoted to the research of the influence of nonlinear effects in optical fibre on the processes of propagation of the optical signal do not consider their influence on the quality of data transmission. However, the influence of nonlinear effects such as: self-phase modulation, cross-phase modulation, stimulated Raman scattering and stimulated Brillouin scattering - leads to the decrease in the power of the optical signal and, as a result, to the reduction of a signal immunity from interferences. Therefore, the main purpose of this article is to study the influence of nonlinear effects on the reduction of optical signal power in the fibre and optical noises.
