Infinera says it has a successfully completed a multi-vendor demonstration of 5G mobile broadband xHaul using coherent open XR optics point-to-multipoint optical transmission. The company says  the multi-vendor interoperability testing, conducted with DZS and Calnex, represents a key step toward enabling mobile operators to greatly simplify and cost-reduce 5G and next-generation mobile transport network rollouts through the reduction of the number of optical transceivers, resulting in significant total cost of ownership savings.

Hosted in the European Open Test & Integration Centre in Torino by TIM, the high-capacity xHaul application testing included fronthaul, midhaul, and backhaul transport scenarios with XR-based coherent pluggable optics deployed in third-party hosts supporting point-to-point and point-to-multipoint optical transmission. Results of the performance testing included successful demonstration of xHaul synchronisation and timing distribution in a point-to-multipoint optical transport architecture.

Equipment used in the interoperable xHaul testing included Infinera ICE-X intelligent coherent pluggables, the DZS Saber 2200, and Calnex Paragon-NEO. Part of the work carried out by TIM and Infinera was supported by the EU project ALLEGRO, GA No. 101092766.

“It is not only the significant bandwidth demands of 5G that create challenges for mobile operators, but also the fundamental misalignment between actual 5G network traffic patterns and the underlying transport technology,” said Ron Johnson, SVP and general manager, Optical Subsystems and Global Engineering Group, Infinera. “Working in close collaboration with industry-leading mobile operators such as TIM, this testing validates the critical role that XR optics innovation can play in transforming the economics of 5G transport and paving the way for efficient 6G networks.”
