Development to High-Rate Fiber Optic Communication Line with Orthogonal Frequency-Division Multiplexing

The main features of the construction of fiber-optic communication lines with multiplexing using orthogonal frequency channel separation for use in optical transport networks, cloud and high-performance computing systems are considered. The methods of increasing the speed of information transmission without complicating the design of existing backbone fiber-optic lines are proposed. The results of studies of signal parameters in the transmission of information over the fiber optic network using the technology of multiplexing orthogonal optical subcarrier channels of different modulation formats are presented. The prospects of further use of the proposed solutions are considered.
