"There are few certainties in life: death, taxes and massively increased workloads on infrastructures through the unstoppable rise of AI. And enterprises and connectivity providers know only too well that AI has fuelled an unprecedented surge in network demand. Keeping pace with the next wave of AI growth will require new long-haul networks to enable the rapid scaling of capacity needs in both existing and emerging enterprise setups - especially within datacentres."
"Looking at the networks of the future, in October 2025 Cisco noted that two major forces are starting to reshape the landscape: AI agents, which raise the bar for scale, security and governance; and AI infrastructure debt, the early warning signs of hidden bottlenecks that threaten to erode long-term value. Assessing in April 2025 how to solve these issues, leading research firm Omdia observed that to drive the continued growth of the global AI economy, networks will need to evolve significantly to deliver enhanced capabilities."
AI adoption has driven an unprecedented surge in network demand, creating rapid, escalating capacity needs within datacentres and enterprise environments. New long-haul and advanced optical networks are required to scale capacity rapidly while meeting tight capex targets. Agentic AI applications increase requirements for scale, security and governance, and growing AI infrastructure debt exposes hidden bottlenecks that can erode long-term value. Core fibre investment is critical, but four-fifths of firms delay builds due to infrastructure constraints. Zayo projects AI-driven datacentre capacity to grow 2–6× over five years; Ciena reports capacity doubling about every six months.
