New telecommunications line deployed in the Far East, utilizing locally produced alternatives to imported hardware
Megafon Launches High-Capacity Trunk Line Using Domestic DWDM Technology
Megafon, a leading telecommunications company, has launched a new trunk line connecting Khabarovsk and Komsomolsk-on-Amur, utilising Dense Wavelength Division Multiplexing (DWDM) technology from Russian manufacturer T8. This marks the first infrastructure project of this scale for Megafon using domestic equipment.
The DWDM system can scale up to 800 Gbps in this direction, offering significant capacity and scalability. By multiplexing multiple wavelengths on existing fiber, DWDM avoids the cost of deploying new cables, making it an efficient solution for expansive routes like the one between the two cities.
The communication channel, over 400 kilometers long, has become an important part of the regional trunk that connects major nodes. Specialists chose DWDM multiplexers from T8 for the project, as they outperform foreign counterparts in several parameters.
Routers installed on the line distribute signals to the appropriate channels, amplify them over long distances, and ensure fast and stable data transmission. Megafon engineers, along with T8 specialists, calculated DWDM system parameters, including transponders and optical amplifiers.
Andrei Krystofovich, Director of Transport Network Development at Megafon, stated that the launch is part of their long-term strategy to develop the network in the Far East. Olga Yanchevskaya, Deputy General Director of T8 for Commerce, mentioned that such projects require precise calculations and adherence to stringent performance and reliability requirements for equipment.
The use of DWDM technology from T8 offers several benefits: high capacity and scalability, cost efficiency over existing infrastructure, flexibility and automation, suitability for long distances, and considerations such as enhanced supply chain security and local support tailored to Russian network conditions. However, it also presents challenges, such as high initial cost, technical complexity, power and space requirements, precision and quality control, and interoperability and standards.
With this successful launch, Megafon aims to consistently implement this DWDM solution in other parts of the trunk network throughout the country. For T8, as developers and manufacturers, this project is not just a challenge, but a direct request from the industry for relevant solutions that can ensure the stability and scalability of modern network infrastructure.
