Summary: The aim is to calculate the parameters of optical filters for multiplexing, demul-tiplexing processes signals in fiber-optic communication lines with spectral multi-plexing. The paper analyzes the impact of the filter parameters based on optical ring res-onator and conducted calculations depending transition fading between the input and output signals. The possibility of applying filters to form equidistantly grid frequen-cy, which allows using rezhektsiyni filter properties to improve the signal / noise ra-tio at the output filter. Calculations shoulders designs depending on the normalized frequency at dif-ferent coupling coefficients k and integral losses in the cavity αl. the value of attenua-tion in the passband nonlinear effects that occur when optical signal passing through lightguide. We describe the design and application of optical filters and optical am-plifiers. Showing generator design solitons. The paper discusses issues of health and safety. Results of work can be used in the design of digital networks Ukraine. Explanatory Note includes 82 pages of typewritten text. It uses 7 tables, 24 fig-ures, 44 formulas, 25 sources of scientific and technical literature, 3 applications.
