TTK IS ONE OF THE TOP-5 RUSSIAN TELECOMMUNICATIONS COMPANIES.
TTK operates one of the largest fiber networks in Russia, which is more than 76 000 km long. TTK implements large-scale telecommunication projects and introduce a full range of telecommunication services for other state companies and end-users.

Why TTK?

1
TTK is one of the TOP-5 Russian telecommunications companies
TTK operates and services one of the largest fiber networks in Russia, which is more than 76 000 km long.
2
Full range of telecommunication services
TTK implements large-scale telecommunication projects for other state companies, large commercial corporations and end-users all over the country.
3
LH DWDM 9,6 Tbps capacity based on 5 circuits
TTK is among five carriers in the world and the only one in Russia who uses terrestrial Long Haul DWDM, 20 000 km lengh (ring structure), uses Cisco equipment.
4
1.6 Tbps network capacity
The network uses SDH multiplexers provided predominantly by Lucent Technologies. These are capable of multiplexing standard PDH and SDH signals to 2.5 Gbps (STM-16).
5
TTK is currently the Telecom Bridge between Asia & Europe
20% of the capacity between China & Europe has been moved from submarine cables to TTK's network over the last 12 years (40% of this capacity currently goes through Russia).
6
High SLA - 99,8%
Fully protected reliable route, technical and geographical risk diversification.

TTK Network

The fiber optic lines which run along all Russia's mainline railways total over 76,000 kilometers.
BDCN covers Russia's more densely populated areas and links western and eastern areas of the country. The Backbone Digital Network has over 1,000 resource allocation points in all regions of the country covering 90 per cent of the population and accommodating all Russia's major production facilities. The high reliability of the network is ensured by the reservation of fiber optic communication lines for geographically spread routs and by an efficient operation system for line-cable structures.
Connection points with the networks of foreign operators make it possible to create an affective environment for the exchange of international operators' traffic.
We provide communication services using the backbone digital communications network of Russian Railways built and operated by TTK and the MPLS IP network deployed on its basis. TTK also has its own access networks.

SDH technology (Synchronous Digital Hierarchy) was chosen as the basic for setting up the backbone primary network to ensure the needed scalability (2 – 10,000 Mbps) in terms of both capacity and zone coverage, and to facilitate the effective operation of optical channels.

The network uses SDH multiplexers provided predominantly by Lucent Technologies. These are capable of multiplexing standard PDH and SDH signals to 2.5 Gbps (STM-16). The wide range of distances covered and high capacity and connection flexibility make the SDH equipment a core component of effective and economical backbone networks. The equipment used with the SDH technology increases primary traffic network reliability by integrating its units into ring configurations. This allows the network control system automatically to switch main the channel to an alternate channel in the case of deviations in the main channel quality parameters from standard. Switching channels on the network takes no more than 50 ms which means there is no user interruption. TTK has implementated DWDM technology into its network. Due to that improvement, the network capacity has grown to 1.6 Tbps.
