Thesis

Data-center hyperscaling for AI demands next-gen networking and rock-solid power infrastructure. Vendors of high-speed optics (ANET, CIEN, CRDO, AAOI, 2345.TW), system controls (SLAB), and rack-power/Cooling (VRT) should see sustained capex as cloud giants expand AI clusters .

Bull case

Hyperscalers (MSFT, META) guided record DC capex in early 2025, underpinning robust order books for connectivity & power vendors
Ciena's global survey forecasts DCI bandwidth demand to rise sixfold by 2028, signaling urgent upgrades in high-speed interconnects
U.S. power demand is reaching new highs in 2024–25 due to AI/data-center growth, driving UPS and power-system investments

Bear case

Macro headwinds and tighter IT budgets could slow data-center build-out and curb connectivity upgrades
Breakthroughs in GPU/interconnect efficiency may halve incremental power and network spend per AI workload
AI build‑outs are kicking off a multi‑year upgrade of both inside‑the‑DC links (800G→1.6T optics, AECs, Ethernet fabrics) and between‑DC backbones (coherent DCI, fresh fiber), constrained by power availability. Winners are optical components/systems (LITE, COHR, AAOI, CIEN), short‑reach interconnect (CRDO), fiber (GLW), network OEMs (ANET, CSCO), power & power‑management (MPWR) and server integrators (DELL, CLS) as utilities and hyperscalers race to secure MWs.

Overview

Hiring Trend Watchpoints

High-performing operators in the AI '25: DC Connectivity theme are intensely focused on scaling infrastructure to meet unprecedented AI demand. Expect a surge in demand for specialized engineering roles, particularly in optical communications, power systems, and advanced cooling. Key roles to monitor include optical/photonics engineers, silicon photonics design engineers, high-voltage power engineers, data center power system architects, liquid cooling specialists, and AI network architects. Geographically, there's a strong emphasis on strengthening domestic supply chains, particularly in the U.S., driving hiring in manufacturing and R&D facilities. Confirming theme execution would be indicated by sustained growth in job postings for these specialized roles, particularly those related to 800G/1.6T optics, co-packaged optics (CPO), coherent DCI, and advanced thermal management solutions. A shift towards hiring for large-scale manufacturing and deployment roles for these technologies would also signal strong execution. Conversely, a deterioration of the theme would be warned by a significant slowdown or decline in job postings for these critical, specialized positions, a notable increase in general IT infrastructure roles over AI-specific ones, or any reported hiring freezes or layoffs within the core optical, networking, and power segments of these companies.

Second Order Trends

Several second-order trends are emerging within the AI '25: DC Connectivity theme. Firstly, **power availability has become the primary bottleneck for AI data center expansion**, shifting from computational efficiency. This is driving data centers to become active grid stakeholders, co-investing in infrastructure upgrades, and deploying on-site power generation and storage. Secondly, there's an accelerated push towards **Co-Packaged Optics (CPO) and Near-Package Optics (NPO)**, moving from demonstration to shipping products in 2026. This is essential for lowering AI factories' power consumption and delivering higher bandwidth as electrical interconnects reach their limits. Thirdly, **liquid cooling systems are rapidly becoming mainstream** due to the extreme power density and heat generated by AI workloads, with modular, high-capacity solutions becoming the de facto standard for new builds. Fourthly, **domestic supply chain strengthening** is a significant theme, with companies like Corning focusing on U.S.-based manufacturing for advanced optical connectivity solutions, driven by strategic partnerships and potentially government initiatives. Lastly, **AI is increasingly being applied to optimize network operations**, predicting network health, localizing faults, and improving utilization, leading to 'self-driving' networks.
