Abstract: In the article, a nonlinear phenomenon SPM (Self Phase Modulation), which occurs in the all-optical communications systems, is described. In the 21st century, the WDM (Wavelength Division Multiplex) system cannot be created without the software that simulates the system under real conditions. The most important WDM components include the EDFA (Erbium Doped Fiber Amplifier), in which amplification occurs at all wavelengths. 10 Gbps optical line of the DWDM (Dense Wavelength Division Multiplex) system in accordance with ITU-T.G.694.1 was created and the SPM phenomenon is observed at it.
