Turkcell and ZTE lead Europe's first commercial deployment of 100G ZR QSFP28-DCO transceivers in an IP network

• Turkcell and ZTE successfully completed Europe's first commercial deployment of 100G ZR QSFP28-DCO transceivers in Diyarbakır, Türkiye, verifying the excellent performance of advanced technologies

Paris, France, 26 March 2025 - ZTE Corporation (0763.HK / 000063.SZ), a global leading provider of integrated information and communication technology solutions, in partnership with Turkcell (NYSE: TKC) (BIST: TCELL), Türkiye's leading telecommunications and technology company, has successfully completed Europe's first commercial deployment of the 100G ZR QSFP28-DCO transceivers in Diyarbakır, Türkiye. This milestone marks a significant advancement in IP+Optical convergence, showcasing innovative features that promise smoother network evolution and reduce optical layer investments.

The project harnesses the unique capabilities of the 100G ZR QSFP28 digital coherent optics (DCO) solution, combined with ZTE's latest aggregation router, taking full advantage of its tunable central wavelength capabilities and innovative IPoWDM technology. This flexibility enables operators to optimize metro transport networks by using existing fiber infrastructure and DWDM networks, maximizing fiber utilization without the need for a comprehensive network overhaul. Furthermore, the solution's seamless compatibility with standard QSFP28 interfaces facilitates a smooth and incremental transition to next-generation 100GE technology.

In addition to these technical innovations, the commercial deployment in Turkcell's live network has achieved a significant milestone by successfully establishing metro-long-haul point-to-point interconnections. This accomplishment is critical for the expansion of modern metro networks. By effectively bridging distant nodes within urban regions, the project guarantees robust, high-capacity data transmission over long distances while substantially reducing infrastructure investment demands. This strategic approach underscores a commitment to cost-effective, high-performance connectivity solutions in densely populated areas.

Prof. Dr. Vehbi Çağrı Güngör, Chief Network Technologies Officer of Turkcell, stated: "Our collaboration with ZTE highlights the transformative potential of IPoWDM technology in strengthening our network capabilities. By seamlessly integrating this solution into our existing DWDM infrastructure, we are advancing toward future-ready IP+Optical convergence. Our goal is to drive digital transformation, enhance connectivity for businesses and consumers, and ensure sustainable and efficient network growth."

Peng Aiguang, Senior Vice President of ZTE, Chairman of Netaş, said: "Our collaboration with Turkcell represents a transformative leap in the convergence of IP and digital coherent optical technologies. By integrating legacy infrastructure with advanced digital coherent technology, we redefine urban connectivity and lay the foundation for resilient, future-proof networks. Looking ahead, ZTE will continue to focus on R&D, deepen collaboration with Turkcell to jointly drive technological innovation, and fully support Turkcell in enhancing its leading market position."

The collaboration between Turkcell and ZTE establishes a new standard for scalability, efficiency, and economic viability in telecommunications. As Europe's  first commercial 100G ZR QSFP28-DCO deployment, this pioneering initiative is poised to serve as a blueprint for future IPoWDM network upgrades across Europe and other key markets.
