Turkcell and ZTE transmit 800 Gbps data over 2000 km

Feb. 29, 2024
The trial highlights the collaboration between Turkcell and ZTE in pushing the boundaries of high-speed data transmission.

Turkcell, Turkiye’s main telecom provider and ZTE, successfully verified terrestrial long-haul transmission over 2000km based on commercial 800G pluggable coherent modules and single carrier architecture without regeneration.

Turkiye occupies a unique geographic position, partly in Asia and partly in Europe, making long-haul transmission a vital necessity for its optical network development.

As one of the largest service providers covering this expansive territory, Turkcell provides lines to major European cities through stand-alone routes with many protection and redundancy scenarios and five European border crossings, which it ensures with its own infrastructure.

With seven eastern border crossings, it ensured that with its infrastructure, Turkcell could render services to the Middle East, the Arabian Peninsula, the Turkic Republic, and the Caucasus.

"As Turkcell, we aim to be the forefront of the digital silk road between the East and West, leveraging Turkey's unique role as a bridge between Europe and Asia,” said Prof. Dr. Vehbi Çağrı Güngör, CTO of Turkcell. Our network is progressing to become a central hub for content providers. As Turkcell, through the collaboration with ZTE, we will facilitate the transmission of very large capacities over long distances from East to West through Turkey."

Various factors are driving Turkcell to examine 800G technologies. Future 5G network deployment and emerging technologies such as cloud computing and digital services intensify the operator's urgent need to enhance bandwidth due to the anticipated significant growth of network traffic.

Turkcell has collaborated with ZTE to verify an 800G pluggable solution based on single carrier future-proof architecture in pursuit of this goal. For this project, ZTE deployed its flagship optical transmission product, the ZXONE 9700. It utilized an 800G pluggable coherent module for long-haul transmission spanning over 2000 km via the terrestrial G.652 optical fiber.

ZTE claims that, unlike the industry's standard 800G fixed module, its platform reduces power consumption by 68%. This strategic approach assists Turkcell's Sustainability Policy in achieving its goal of establishing green and low-carbon optical networks.
