INCREASING THE CAPACITY OF SPECIAL-PURPOSE OPTICAL TRANSPORT NETWORKS THROUGH EFFICIENT USE OF LEASED SPECTRAL RESOURCES

Modern special-purpose optical transport networks are formed on the basis of leased telecommunication resources, the types of which are constantly being improved, giving rise to both additional opportunities and new types of threats. One of the most anticipated scenarios for the development of optical communications is the transition to spectrum leasing in the fiber-optic infrastructure of telecom operators. This will increase the capacity of special-purpose optical transport networks by optimizing the distribution of spectral channels. The article presents the directions for the development of telecommunication services, the leasing of which will increase the efficiency of special-purpose optical transport networks. The issue of the emergence of a system of additional threats caused by multiple access to elements of the physical infrastructure of public communication network operators is raised.
