AI infrastructure connectivity and optical technology trends

Overview

The focus of AI infrastructure development is shifting from the procurement of GPUs and High Bandwidth Memory (HBM) toward the connectivity between components. As AI data centers expand, traditional copper-based electrical connections are facing limitations regarding power efficiency and signal attenuation. To address this, optical communication technology is emerging as a critical solution, involving a transition from long-distance rack-to-rack connections to Co-Packaged Optics (CPO) and the eventual optical conversion of GPU chip interfaces. Surging data-center traffic has created acute shortages of high-speed optical components, forcing cloud builders to expand their vendor pools to mitigate physical bottlenecks. Market trends indicate a structural shift toward optical networks as copper cables reach physical limits due to heat loss and energy inefficiency. The adoption of 800 Gigabits per second optical transceivers is expected to grow significantly, with market share projected to rise from 19.5 percent in 2024 to over 60 percent by 2026. Recent technological advancements are accelerating to meet the data movement demands of next-generation AI clusters. LightSpeed Photonics has demonstrated a compact 400-Gbps optical interconnect component for CPO that operates at less than 2 W, while also developing PCIe-over-fibre technology to potentially allow the physical separation of compute, storage, and memory resources. ams OSRAM has unveiled Thin-Film VCSEL technology featuring micro-emitter arrays for highly parallel optical architectures, showcased alongside a connectorized multi-core fiber solution with partner BizLink. Furthermore, Openlight has begun sampling 3.2 Tbps DR8 silicon photonics Photonic Integrated Circuits (PICs), expanding the hardware available for high-bandwidth connectivity. By late 2026, the rapid expansion of AI infrastructure has driven a massive surge in demand for optical fiber. Architectural shifts are significantly increasing fiber density requirements; for instance, fiber needs per rack are projected to grow from 1,000 in older architectures to 64,000 in upcoming Vera Rubin architectures.
