Towards AI-centric all-optical telecommunications networks infrastructure evolution to sustain data growth

Digital infrastructure is undergoing rapid transformation as the volume and diversity of data traffic continue to grow. Over the past few decades, residential internet speeds have increased significantly, while new digital practices (high-definition streaming, online gaming, artificial intelligence, immersive environments, and connected devices) have intensified the pressure on telecommunications networks.

To meet these evolving requirements, it is necessary to make coordinated upgrades across the entire network stack. Improvements are needed not only in backbone transport systems, but also in metropolitan networks, access infrastructure, home connectivity, and datacentre interconnections. Today’s digital services depend on high throughput, minimal latency, and robust reliability guarantees.

This report explores the key drivers of network traffic growth and reviews the technology developments that will enable future capacity growth. It focuses on next-generation Wi-Fi standards, fibre-to-the-room architectures, XGS-PON fibre access systems, high-capacity optical transmission technologies, and datacentre interconnect networks.

The report indicates that telecommunications infrastructure is gradually moving towards an integrated optical architecture in which fibre connectivity supports all major network segments. In such an environment, AI-based services and data-intensive applications can be delivered while maintaining scalable and predictable performance.
