Nokia, Viettel, successfully complete first Vietnamese 600G DWDM network

News and Business

Nokia has announced the completion of the first DWDM network operating at 600G per wavelength with Viettel, Vietnam’s largest telecom service provider. The network uses Nokia’s PSE-V super-coherent optical engines (PSE-Vs), transmitting a 600Gbps channel in the C-band to connect Viettel’s main core sites. The DCI solution will enable Viettel to meet future requirements for low-latency, high-capacity, robust network for 5G, Cloud, and growing consumer demand for online video and internet usage.

Nokia’s PSE-Vs is deployed in Nokia’s 1830 Photonic Service Switch platform (pictured), and will enable Viettel to scale total network capacity to 25.2Tbps 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 and 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 at 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 optimise 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.”
