Features of construction of fiber-optic communication lines with orthogonal frequency-division multiplexing

The necessity of studying the features of building fiber-optic communication lines with multiplexing using orthogonal frequency division of channels is substantiated. The main properties of such systems are considered, as well as ways to improve operational characteristics to improve the quality of communication and economic benefits are studied. The necessity of developing such systems for future use in optical transport networks, cloud and high-performance computing systems is substantiated.
