Telia Carrier and Infinera claim ‘industry-first’ for autonomous intelligent transponder’s live network field trial

Mattias Fridström of Telia Carrier

Infinera and Telia Carrier have completed what is said to be 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 fibre optic transmission systems to autonomously adapt to changing network conditions in real time. This is to support optimal service quality and performance while simplifying operations.

“As mission-critical Internet of Things (IoT) applications drive increased demand for low-latency, high-quality network connectivity – at all times – the underlying optical infrastructure will require a new level of responsiveness and adaptability,” says Mattias Fridström, chief evangelist, Telia Carrier.

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 fibre 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, minimising network cost and maximising performance, including total fiber capacity throughput and spectral efficiency.

“We are pleased to extend our long-standing collaboration with Telia Carrier, a company distinguished by their unwavering commitment to redefining customer value through cutting-edge technology innovation,” said Parthi Kandappan, chief technical officer at Infinera.

“This field trial reinforces the importance of advancing the agility of high-capacity infrastructure through innovation in cognitive networking, one of the pillars of our vision of the Infinite Network.”

At the Optical Fiber Conference and Exhibition (OFC) in San Diego, California this week, Infinera is showcasing its ongoing technology collaboration with Telia Carrier. This includes results from recent field trials featuring AIT technology, 600 gigabits per second transmission and real-time optical performance awareness based on the Infinera Aware solution.
