Nokia has announced a high-capacity optical network rollout with Viettel, Vietnam’s largest service provider.
Following a successful trial, which set a record transmission speed of 1.2 Tbps per wavelength, Viettel will deploy Nokia’s sixth-generation Photonic Service Engines (PSE-6s) and the 1830 Photonic Service Switch (PSS) to improve scalability and energy efficiency. The deployment will connect Viettel’s data centers across major cities, including Hanoi, Ho Chi Minh City, and Da Nang, with an expected completion date in 2025.
Nokia’s optical solution, powered by PSE-6s, enables Viettel to support up to 38.4 Tbps of network capacity over C-band, while also reducing power consumption by up to 60%. The technology supports high-density services, including 3 x 800GE or 6 x 400GE on a single line card, allowing Viettel to efficiently scale and future-proof its network for 5G and cloud-based applications.
• Viettel deploys Nokia’s optical network to meet demand for 5G, DCI, and data consumption.
• Trial achieved record transmission speed of 1.2 Tbps per wavelength.
• Nokia’s PSE-6s supports 38.4 Tbps capacity over C-band and improves energy efficiency.
• High-density support includes 3 x 800GE or 6 x 400GE on one line card.
• Project completion expected in 2025 across key cities in Vietnam.
Nguyen Van Yen, Head of Viettel Regional Transmission, said: “The smooth execution of the record-breaking trial convinced us that Nokia was the right partner for this crucial initiative. Now, we are delighted with the seamless deployment of Nokia’s innovative PSE-6 super-coherent optical engine, which will provide the required capacity for our existing and growing needs while making us ready for 5G and cloud-based use cases.”
