description: The object of the study is DWDM system. The aim of the work is to disassemble DWDM-system structure, the principle of its operation, the process of multiplexing channels in Gazprom transgas Saint Petersburg, calculate the attenuation, OSNR and chromatic dispersion on this FOCL, as well as to select appropriate elements in the system for its performance. In the course of the study the following tasks were performed: 1. A review of methodological guidelines "Operation and maintenance of DWDM equipment "Volga" in the literature was conducted. 2. The principle of DWDM-system structure was studied on the example of the system installed at Gazprom transgaz Saint-Petersburg. 3. The analysis and processing of the obtained results and data related to DWDM-system was performed. 4. Conclusions were formulated based on the results and analysis of the DWDM system. 5. The calculation of line attenuation in the DWDM system was performed. As a result of this work it was found that the DWDM system is a complex set of various components, such as amplifiers, transponders, multiplexers and regenerators. It facilitates the transmission of high-speed signals over long distances by combining multiple signals in a single optical cable. To achieve optimum dispersion, OSNR and BER values, the appropriate elements and targets for the installation of this system must be chosen.
