Fiber-optic backbones laid along main railway tracks have a total length of over 53,000 kilometers. In fact, the DBN covers the entire densely-populated territory of Russia, connecting its western and eastern borders. The digital backbone network has more than 1,000 points of resource allocation in all regions of the country where the main industrial resources of Russia are concentrated.

High network reliability is ensured by redundancy of fiber-optic links along geographically distributed routes and established system of line-cable facilities operation.

Points of interaction with operators' networks of other countries (Finland, the Baltic States, Poland, Belarus, Ukraine, Azerbaijan, Kazakhstan, Mongolia, China, and Japan) allow the creation of an effective environment for transmission of international operators' traffic.
