Ciena lifts full-year outlook as AI-driven optical demand surges
Hyperscale cloud providers and service providers are driving unprecedented investment in fibre infrastructure, prompting Ciena to raise its fiscal 2026 revenue guidance to $6.3 billion.
Ciena Corporation has reported a 40 per cent year-on-year increase in revenue for the second quarter of 2026, a performance driven by strong demand from hyperscale cloud providers and service providers for optical infrastructure. The company has raised its fiscal 2026 revenue guidance to $6.3 billion and reported a record backlog of $7.7 billion, representing a sequential increase of more than $600 million. Management clarified that these orders reflect immediate deployment needs rather than inventory buffering, providing high visibility into 2027 and beyond.
Growth in the Routing and Switching segment was attributed primarily to the expansion of Data Center Out-of-Band Management (DCOM) solutions. Ciena highlighted strategic wins with major hyperscalers for high-performance Coherent modules, noting that DCOM applications are evolving into a durable, multiyear platform with a potential addressable market of $3 billion by 2029. The company also secured a competitive win for a multi-rail standardisation deal for high-intensity AI training, with deal sizes typically reaching hundreds of millions of dollars over multiple years.
Service provider revenue grew by 28 per cent, reflecting a cyclical reinvestment in optical fibre networks after years of prioritising 5G infrastructure. Ciena is capitalising on new Managed Optical Fiber Network (MOFN) opportunities as the addressable market for traditional WAN and data centre applications is projected to double to approximately $50 billion by 2029. Interconnect revenue, specifically 400-gig and 800-gig pluggables, is on track to more than double from 2025 levels as hyperscalers scale metro and long-haul networks.
To navigate a constrained supply environment, Ciena is investing between $250 million and $275 million in capital expenditure to secure future supply and manufacturing capacity. The company is leveraging its vertical integration, particularly in modems, to buffer against industry-wide component shortages. Management expects to exit fiscal 2026 with an even higher backlog than the current $7.7 billion, assuming the continued ability to manage supply constraints and deliver on existing orders.
Gross margin expansion is anticipated through value exchange strategies, including price optimisation, engineering cost reductions, and balancing supply chain risks with customers. While operating expenses were elevated due to higher variable compensation tied to strong performance, management expects to maintain operating leverage as revenue grows faster than expenses. The launch of the RLS Hyper-Rail is expected to drive a meaningful revenue uptick in 2027, targeting high-intensity AI training requirements across greater distances.
