Telia Carrier and Infinera have completed network field trial demonstrating autonomous intelligent transponder (AIT) technology.

The ‘industry-first’ live field trial was carried out as part of the Celtic-Plus project called SENDATE, a research program focused on devlepoing concepts and solutions for things like VNF and high-speed transport networks to interconnect servers in a data centre to end users.

Through the trial, the companies where able to demonstrate the ability of fibre-optic transmission systems to autonomously adapt to changing network conditions in real time to support optimal service quality and performance while simplifying operations.

“As mission-critical Internet of Things 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,” said Mattias Fridström (pictured), chief evangelist at Telia Carrier. “We continue to team with industry-leading innovators like Infinera to push the boundaries of optical layer automation to help us deliver a best-in-class customer experience under any network conditions.”

The proof of concept trial was delivered using AIT prototype technology from Infinera as part of its research and development initiatives. The demonstration was carried out on a live 1,500km fibre route in Telia Carrier’s backbone network connecting Munich, Zurich, Strasbourg and Frankfurt. The trial also featured multiple use cases that tested AIT capabilities under varied channel conditions and quality impairments, including the impact of neighbour channels, ageing components and the adding and dropping of channels.

“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,” added 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.”

The result of the trial was that in all cases the AIT autonomously adapted transmission parameters such as modulation schemes, minimising network cost and maximising performance, including total fibre capacity throughput and spectral efficiency.
