Research and Analysis Efficiency Optical Telecommunication Networks on the Basis Optical WDM and DWDM Technologies

The performance characteristics of optical transport communication networks based on the technology of spectral separation of channels using a transmitting and receiving optical module (TOM and ROM) are analyzed. The performance indicators of optical transport networks based on optical WDM & DWDM technologies are investigated and a method for calculating an optical signal transmission system (OSTS) is proposed. This method takes into account the principles of spectral separation of optical channels and operation algorithms, the functioning scheme of the studied fiber-optic transmission systems, as well as information security indicators of fiber-optic communication lines using quantum cryptography. Based on the calculation method, important analytical expressions were obtained that evaluate the performance indicators of multiservice optical telecommunication networks based on the FN (Future Network) architectural concept using SDN (Software Defined Network) technology.
