Infinera and Telia Carrier have conducted a field trial over a production network of autonomous intelligent transponder (AIT) technology. AIT, developed by Infinera, aims to enable fiber-optic networks to autonomously adapt to changing conditions to maintain optimal performance. The technology trial was conducted for the Secure Networking for a Data Center Cloud in Europe (SENDATE) project within the Celtic-Plus initiative.
The field trial leveraged a live 1,500-km fiber route connecting Munich, Zurich, Strasbourg, and Frankfurt in Telia Carrier’s backbone network. The trial demonstrated the AIT technology’s ability to adjust to various channel conditions and impairments, including the effects of neighboring channels, aging components, and channel add/drops. The AIT, a prototype version of which was used in the trial, adjusted to these network conditions by adjusting transmission parameters such as modulation schemes to optimize capacity and reach.
“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, chief evangelist, 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.”
SENDATE is investigating technology and architectures to meet emerging data center transmission requirements, both within facilities and between them. Software-defined networking/networking function virtualization (SDN/NFV), security, and high-speed, flexible transport are areas under research within the program.
