The Backbone of AI Innovation: How Fiber Networks Drive the Future
by Sean Baillie, SVP of Carrier, Channel and Hyperscale
Artificial Intelligence (AI) is reshaping industries, unlocking efficiencies, and creating opportunities that were unthinkable even a few years ago. From ChatGPT and DeepSeek to enabling real-time logistics visibility and medical diagnostics, AI is becoming the driving force behind global innovation. There are daily news stories about AI innovation, some of which analyze the massive infrastructure investments that are required for AI to reach its potential. It is not well known that AI depends on a sophisticated ecosystem of infrastructure that includes GPUs, data centers, power and fiber networks.
Fiber Networks: The Silent Enabler of AI Progress
To appreciate the role of fiber, you first have to understand the sheer scale of AI’s data demands. Training an AI model requires moving vast amounts of data across data center campuses and eventually geographies. Only fiber networks, with their unmatched capacity, reliability, and ultra-low latency, have the ability to support the massive movement of data that is required for AI to function.
Consider this: when an AI model is in training, petabytes of data are processed, transferred, and re-analyzed every second—often between multiple data centers. This is where Data Center-to-Data Center connectivity becomes indispensable. Without robust, scalable fiber connections, AI models would be bottlenecked, unable to reach their full potential. And as AI applications grow more complex and pervasive, the roll of fiber as a required enabler of scalability becomes even more critical.
The Connective Tissue: GPUs, Data Centers, Power and Fiber
AI relies on a trifecta of components to deliver its value:
- AI Chips: GPUs, TPUs, and other processors perform the heavy lifting of training and inference, processing massive datasets.
- Data Centers: These hubs house the computational power required for AI, storing and processing data at scale.
- Power: the AI data centers/data center campuses require Megawatts and Gigawatts of power today with growing consumption in the future.
- Fiber Networks: The backbone that connects it all, ensuring the movement of data between chips, data centers, and across geographies.
This interconnected system ensures AI applications can operate in real time as they scale. Regardless of the AI use case, fiber ensures that the ecosystem functions as a cohesive whole, enabling distributed computing and real-time processing on a regional, national and global scale. The scalability of fiber networks also supports the expansion of AI’s capabilities, making it possible to deploy more advanced use cases across industries.
AI and Internet: A Symbiotic Relationship
AI relies on the power of GPUs and data centers, working together to deliver its capabilities to users via the internet. This interconnected system must be in harmony and assure access to scalable bandwidth.
- AI Platforms: Hyperscalers such as AWS, Microsoft/OpenAI, Google and X provide the elasticity needed for AI workloads, scaling compute resources as demand fluctuates. Fiber networks link these environments, ensuring enterprises can leverage cloud-based AI tools seamlessly.
- The Internet: The final delivery mechanism that connects AI applications to end-users. Whether it’s a real-time language translator or a predictive analytics dashboard, the internet ensures AI insights are accessible when and where they’re needed.
Our role is to provide the fiber infrastructure and services that tie these elements together, ensuring fast, reliable and secure connections between AI ecosystems, internet handoffs and end users.

Looking Ahead: Fiber’s Role in the Future of AI
As AI continues to evolve, so will its demands on infrastructure. Future breakthroughs, from edge computing, AI-driven robotics and potentially AGI, will require even larger, more resilient connectivity. Fiber networks will remain at the center of this evolution, providing the essential underlying foundation on which the rest depends. Fiber and AI together represent a necessary and unstoppable combination. In a world increasingly shaped by AI, one truth remains clear: the future runs on fiber.
