Abstract
Background. The amount of data generated, transmitted and accumulated in the world is constantly growing every year. On the other hand, users need new services and information exchange capabilities. 5G technology is able to meet the requirements of subscribers to some extent. Therefore, it is important to consider the main features of fifth generation mobile networks and to determine the requirements for the design of optical transport networks that will ensure the successful implementation of 5G technology.Objective. The aim of the paper is to determine the features of design and characteristics of optical transport networks to implement the capabilities of 5G technology.Methods. The analysis of the publications devoted to modern optical networks and their optical components allowed defining the basic requirements to design of optical transport networks and their characteristics.Results. It is established that optical transport networks should provide increased bandwidth; possibility of mass optical cross-connections in ROADM/OXC nodes that support addition/removal of any wavelength from/in any direction; intelligent operation and maintenance of the network.Conclusions. The defined requirements for the design of optical transport networks and their characteristics will ensure the successful implementation of the capabilities of 5G technology, which will meet the needs of subscribers.
