Türk Telekom and ZTE Test 1.6 Tbit/s Network
Türk Telekom and ZTE have successfully completed the first real-world trial of a 1.6 Tbit/s integrated C+L band network. The test, announced from MWC Barcelona, marks a significant step toward developing the next generation of 5G all-optical networks.
The breakthrough trial utilized a combined 12 THz of spectrum across the C and L bands of fiber optic light. This technology essentially doubles the data-carrying capacity of existing fiber infrastructure by using two wavelength ranges instead of one, avoiding the need to lay new cables. Conducted on Türk Telekom's live network in Istanbul, the test spanned two continents and successfully transmitted ultra-high-speed 400GE and 800GE services. The system allows for seamless switching between the C and L bands through a unified management system without requiring physical network modifications. ZTE's 1.6T optical module provides a 25% reduction in power consumption per gigabit compared to the previous 1.2T generation, contributing to greener network development. The trial also incorporated an AI-driven management system capable of proactive risk prevention and faster fault diagnosis. Türk Telekom is Türkiye's largest integrated telecom operator, managing a fiber network stretching 514,000 kilometers. The company recently renewed its concession with the Turkish government until 2050, committing to a $17 billion investment in the nation's digital backbone, including fiber networks, data centers, and 5G. Technology partner ZTE has achieved the fastest growth in the global optical network market share from the second quarter of 2023 to the first quarter of 2024. This trial aligns with its focus on developing high-capacity, intelligent, and cost-effective optical network architectures.
