In this paper, the results of experimental research on the ability to create signal amplifiers in the optical domain based on the Raman scattering effect are presented and the method of manufacturing high-power laser pump source into SMF fiber-optic environment, combined with optimizing the design of integrated optical components specialized in photonic modules is described. Pump lasers are selected with the wavelengths of 1424nm and 1452nm, respectively, to create amplification effects for the OSC signal (OSC-Optical Supervised Channel) and the C-band signal (wavelength 1525-1565nm). The authors have created a control circuit for high power pump lasers, combining the research and selection of photonic module components with appropriate technical properties to create Raman amplification effect in C-band wavelength spectrum region. The research results have been integrated into finished products for applying in long-distance optical transmission systems.
