ZTE Corporation and Türk Telekom have jointly completed the world's first C+L (12 THz) full-band integrated 1.6Tbps live network trial in Istanbul. The trial has significantly boosted system capacity, reduced spare part types, and enabled ultra-high-speed 400GE/800GE service transmission, laying a solid foundation for Türkiye to develop ultra-broadband and intelligent all-optical networks, thereby elevating the digital economy level of Türkiye and even Eurasia. To address the rapidly growing demand for data traffic, Türk Telekom and ZTE conducted a transcontinental live network traffic trial in Istanbul, deploying ZTE's C+L full-band integrated 1.6Tbps solution.
This solution supports seamless switching between the C-band and L-band via a unified management system, with no physical network modifications required. While fully leveraging existing fiber infrastructure, it achieves efficient utilization of the full optical spectrum, building a cost-effective, high-capacity, and highly flexible optical network architecture to support rapid response to traffic growth and meet future high-speed network demands. The trial also introduced a new intelligent network management system, relying on a holographic optical solution with capabilities in optical sensing, provisioning, diagnosis, and optimization, achieving full visibility, manageability, and controllability of the network.
Through intelligent functions such as transport capacity mapping, network health assessment, fault diagnosis analysis and the same optical cable and same route, it enables full lifecycle management of network resources, real-time visibility of alarms and performance data, and proactive prevention of potential risks, significantly reducing fault resolution time and enhancing network operational efficiency and stability.
