Türk Telekom and ZTE Pioneer Landmark 5G Optical Network Test with 1.6Tbps Speed

A New Era in Telecommunications

In a significant development for the telecommunications industry, Türk Telekom and ZTE have successfully conducted the world's first C+L full-band integrated live network test with a remarkable capacity of 1.6 terabits per second (Tbps). This trial, carried out in Istanbul, is set to reshape the future of 5G networks by significantly boosting system capacity while also reducing the types of spare parts required in network management.

The C+L technology utilized in this test is a state-of-the-art solution that supports seamless switching between C-Band and L-Band frequencies through a unified management system. This eliminates the need for extensive physical network changes, thus ensuring a more efficient use of the existing fiber infrastructure. By leveraging the full potential of the optical spectrum, the new system enables the creation of a cost-effective and highly flexible optical network architecture that can adapt rapidly to the increasing demands for high-speed data services.

Smart Network Management

Integral to this innovative trial was the introduction of a new intelligent network management system. This system relies on holographic optical solutions that facilitate optical capture, provisioning, diagnostics, and optimization. It provides full transparency, manageability, and control over the network operations. With functions such as transport capacity mapping and network state assessment, it allows for comprehensive lifecycle management of network resources. Additionally, real-time alert transparency and performance metrics significantly enhance network efficiency, reduce operational risks, and lower troubleshooting times.

Ebubekir Şahin, CEO of Türk Telekom, stated, "This pioneering test run with ZTE is another milestone in Türk Telekom's continuous leadership in establishing the most advanced optical transmission infrastructure in Turkey. We have demonstrated our ability to rapidly scale capacity where needed without replacing the entire network, setting a new benchmark in the industry. We are introducing a flexible, cost-efficient, and sustainable infrastructure model that can respond quickly to rising traffic demands and meet future high-speed requirements."

On the other hand, Ling Zhi, Vice President of ZTE, highlighted the implications of the test: "This world-first live network trial not only showcases the practical application of our globally tested optical transmission technology and AI-managed networks but also indicates how such innovations can transform the critical infrastructure in Turkey. By providing higher capacity with a simplified hardware structure and autonomous operational capabilities, we are paving the way for next-generation optical networks meant for High Intelligence and High Performance (HI-OTN), accelerating the country's digital transformation."

The Path Forward

With such advancements, both Türk Telekom and ZTE are poised to redefine the landscape of telecommunications not just in Turkey, but across Eurasia. This trial serves as a stepping stone towards the establishment of all-optical networks that are designed to support ultra-high-speed internet services, ultimately fostering an environment conducive to digital economic growth.
