News Summary:

On October 8, 2026, UK broadband provider Openreach deployed Ciena's optical networking technology to offer wholesale customers flexible tailored options for services requiring large amounts of data, building on a long-standing relationship between the two companies. Earlier that day, Gautam Billa, Ciena’s Chief Technology Officer and Vice President of Solutions Engineering for Asia Pacific Japan and India (APJI), stated that the increasing adoption of AI agents could force operators to rethink network capacity. Billa highlighted that the network connecting computing resources is likely to become a bottleneck in India’s AI push, as AI agents drive up data usage beyond traditional assumptions about human data consumption.
