Nokia announced that it had completed the first 600G DWDM network with Vietnam Telecom, the largest telecom service provider in Vietnam and one of the top 20 telecom companies in the world. The network uses Nokia’s innovative PSE-V hyper-coherent optical engines (PSE-Vs) to transmit 600Gb/s channels in the C-band and connect the main core sites of Vietnam Telecom. This new data center interconnection solution will enable Viettel to meet the future demand for 5G, cloud, low latency, high capacity, and strong network, as well as the growing demand of consumers for online video and Internet use.

In this project, Nokia PSE-Vs is deployed on the Nokia 1830 photon service switch platform, which will enable Viettel to expand the total network capacity to 25.2Tbps in the C-band. In addition, the existing C-band system can be seamlessly upgraded to the C+L-band by adding L-band components, which will double the network capacity.
Rub é n Mor ó n, head of Nokia’s Vietnam market department, Flores, said: “We are very happy to cooperate with Vietnam Telecom as a strategic partner. This project is the first project in the Asia-Pacific region to use our PSE-Vs chipset and was implemented at the peak of the COVID pandemic. Its success shows our strong partnership and unwavering commitment to maintain the leading position by providing Viettel with the latest optical technology and solutions.”
Nguyen Khac Tinh, chief architect of Viettel Optics, said: “This project is very important for Vietnam Telecom, which can meet the high demand of the rapidly growing transmission capacity every day. By using Nokia’s industry-leading continuous transportation solution, we will be able to optimize the cost of capital expenditure/operating expenditure and provide guarantee for future expansion. This is a real network, not only for today, but also for tomorrow. We hope to cooperate with Nokia to further develop us ‘s network. Our network is now ready for 800G, and we plan to reach 1Tbps/channel or higher. “
