This initiative aims to meet the increasing demand for 5G, Data Center Interconnect (DCI), and cross-border connectivity. The collaboration follows a successful trial during which Nokia’s PSE-6s achieved a record transmission speed of 1.2 Tbps per wavelength in real-world conditions. The deployment, expected to be completed by 2025, will enhance connectivity between Viettel’s data centers in major cities, including Hanoi, Ho Chi Minh City, and Da Nang, improving capacity and energy efficiency.
Nokia’s new optical solution, utilizing the PSE-6s technology, will enable Viettel to scale its network while maintaining high performance efficiently. The solution supports three 800GE or six 400GE services on a single line card, allowing Viettel to increase its total network capacity to 38.4 Tbps over the C-band. Additionally, this technology is expected to help Viettel reduce network power consumption by as much as 60%.
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.”
Vito Di Maria, Head of Optical Networks at Nokia Asia Pacific, emphasized the challenges service providers face due to rising data traffic, highlighting the importance of scalable optical networks. He noted that Nokia’s PSE-6s technology will enable Viettel to effectively meet increasing data demands while improving network reliability and energy efficiency.
