Nokia today announced that Vietnam’s largest service provider, Viettel will use its optical transport solution to cost-effectively address the ever-growing demand for 5G and Data Center Interconnect (DCI), consumer data consumption, and cross-border connectivity, Cyber Era NG learns.

The deployment follows the successful trial of Nokia’s PSE-6s with Viettel, which set an optics transmission speed record of 1.2Tb/s per wavelength in a real-world environment. The deployment, to be completed in 2025, will be used to connect Viettel’s data centers in key metropolitan areas such as Ha Noi, Ho Chi Minh City, and Da Nang, enabling the service provider to increase capacity while enhancing energy efficiency.

Powered by Nokia’s PSE-6s, the new optical solution will allow Viettel to scale easily while ensuring superior network performance. In this project, Nokia’s solution supports 3 x 800GE or 6 x 400GE services on a single line card and will enable Viettel to scale total network capacity to 38.4Tb/s over C-band. Nokia’s solution will also help Viettel reduce network power consumption by up to 60 per cent.

Head of Viettel Regional Transmission, Nguyen Van Yen 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.”

Head of Optical Networks at Nokia Asia Pacific, Vito Di Maria, said: “Service providers are grappling with the ever-increasing data traffic, making it crucial to have scalable optical networks. Our industry-leading PSE-6s will allow Viettel to not only cost-effectively address the growing data demand but also enhance network reliability and energy efficiency. We look forward to continuing our longstanding partnership with Viettel.”
