Deploying optical transmission network with speed up to 1.2Tb/s in Vietnam

On November 6, Nokia announced that Vietnam's largest telecommunications service provider, Viettel Military Industry and Telecoms Group, will use Nokia's optical transport solutions to effectively meet the growing demand for 5G connectivity, data center interconnection (DCI) and international connectivity.

This project was implemented after Viettel successfully tested a transmission solution with Nokia's new generation PSE-6 chipset, achieving a record optical transmission speed of up to 1.2Tb/s per wavelength in a real environment.

This project will be completed in 2025 and will be used to connect Viettel's data centers in major cities such as Hanoi, Ho Chi Minh City and Da Nang, helping Viettel expand capacity and optimize operating costs.

Equipped with Nokia's most advanced 6th generation optical processing chip (super-coherent Photonic Service Engines - PSE-6s), the new optical transmission solution will help Viettel easily expand capacity while still ensuring outstanding network performance.

In this project, Nokia's solution can simultaneously provide 3 800GE interfaces or 6 400GE interfaces on a single board, helping Viettel increase the total available transmission capacity to 38.4Tb/s on a pair of optical fibers (C-band). This Nokia solution will also help Viettel reduce the system's power consumption by up to 60%.

“The record-breaking optical transmission speed test has convinced us that Nokia is the right partner for Viettel’s transmission network,” said Nguyen Van Yen, Viettel’s regional transmission officer. “We are delighted to deploy the transmission solution with the new generation PSE-6 chipset. This solution will provide the capacity needed to meet our current and growing needs while also preparing us for 5G and cloud computing.”

"Telecom service providers are facing many challenges with increasing data traffic, and that makes having a scalable optical network environment extremely important. Our new generation PSE-6 chipset will help Viettel not only meet the increasing data demand in a cost-effective way, but also improve the reliability and energy efficiency of the network," said Vito Di Maria, Director of Optical Network Solutions, Nokia Asia Pacific.
