Viettel, Vietnam’s largest telecom service provider, has deployed 600G wavelengths in the C-band to connect core sites using Nokia's PSE-V super-coherent optical engines (PSE-Vs).
In this project, Nokia PSE-Vs is deployed in Nokia’s 1830 Photonic Service Switch platform, and will enable Viettel to scale total network capacity to 25.2 Tbps over C-band. In addition, the existing C-band system can be seamlessly upgraded to C+L band by adding L band components, which will double the network capacity.
Rubén Morón Flores, Head of Market Unit Vietnam at Nokia, said: “We are pleased to work with Viettel as a strategic partner. This project was the first in APAC to use our PSE-Vs chipset & implemented during the height of Covid pandemic. Its success showcases our strong partnership and unwavering commitment to maintaining leadership by delivering latest optics technologies and solutions to Viettel.”
Nguyen Khac Tinh, Optics Principle Architect of Viettel, said: “This project is very important to Viettel to fulfil the high demand for transmission capacity which increases dramatically every day. By using Nokia’s industry leading coherent transport solutions, we’ll be able to optimize our cost for both CAPEX/OPEX and stay secured for future expansion. This is truly a network built not just for today, but for tomorrow as well. We wish to work with Nokia to evolve our network even further. Our network is now ready for 800G and we plan to reach 1Tbps/channel and beyond.”
