Built for every AI environment
Whether you are a cloud or AI provider, service provider, or enterprise, AI readiness demands solutions built for your unique operational pressures so you can scale predictably, protect critical data, and anticipate what's to come.
Simplify and optimize data center management infrastructure
Discover how Ciena and Meta reimagined data center management with a PON-based architecture—reducing rack space by up to 99%, lowering power consumption, and simplifying remote access. This white paper examines how operators can move beyond legacy out-of-band (OOB) architectures to a more scalable and efficient approach.
Ciena’s Data Center Out-of-Band Management (DCOM) solution dramatically reduces the space, cabling, and power required to support OOB management traffic across modern data centers, hyperscale networks, and multi-tenant environments, including colocation facilities.
Build or buy—there’s no wrong answer. But execution is everything.
AI and blockchain are transforming competitive advantage—but only for those who can move data faster, safer, and smarter. From accelerating model training to securing global ledgers, infrastructure decisions about how you connect sites, systems, and partners can make or break performance.
That’s why more leaders are asking: Should we build or buy our network core?
Build
Building your own AI infrastructure gives you complete control over fine-tuned performance and customization. But scaling efficiently requires expertise.
Ciena delivers the high-capacity, low-latency optical networking to make it work.
Buy
Buying scalable AI solutions accelerates deployment, minimizes upfront costs, and ensures access to cutting-edge infrastructure.
Ciena provides the high-performance interconnectivity to power AI workloads.
Dark, lit, or hybrid fiber?
The key to choosing wisely
There's no one-size-fits-all answer. The right decision starts with the right questions. Ciena's Kevin Sheehan breaks down how to evaluate network control, cost, and complexity for AI and blockchain workloads.
Services to support your AI journey
AI puts new pressure on networks—faster turn-ups, bigger capacity swings, tighter reliability expectations, and higher security scrutiny. Ciena Services helps you plan, build, optimize, and operate with confidence—reducing risk and accelerating time-to-value as AI demand grows.
