Infinera and Telia Carrier have completed what they are calling an industry-first production network field trial demonstrating autonomous intelligent transponder (AIT) technology. The live field trial, performed in the framework of Celtic-Plus project SENDATE, demonstrated the ability of fiber optic transmission systems to autonomously adapt to changing network conditions in real time to support optimal service quality and performance while simplifying operations.
The proof of concept field trial was performed using AIT prototype technology developed by Infinera as part of its ongoing research and development initiatives. The AIT trial was conducted on a live 1,500-kilometer fiber route in Telia Carrier’s backbone network connecting Munich, Zurich, Strasbourg and Frankfurt. The trial featured multiple use cases that tested AIT capabilities under varied channel conditions and quality impairments, including the impact of neighbor channels, aging components and the adding and dropping of channels.
In all cases, the AIT autonomously adapted transmission parameters such as modulation schemes, minimizing network cost and maximizing performance, including total fiber capacity throughput and spectral efficiency.
