AI's Next Act: Connectivity Poised for Massive Growth
18 Sep
Summary
- Lumentum's optical technology is key to advanced AI systems.
- Optical fiber will replace copper for faster AI data transfer.
- AI infrastructure connectivity market could grow 100x.

Nvidia's innovations in GPUs and software ignited the artificial intelligence revolution. However, as AI development progresses into its global rollout phase, other infrastructure components are experiencing hypergrowth. Connectivity technology, particularly optical fiber, is projected to significantly outpace other areas.
Advanced AI systems necessitate numerous GPUs communicating seamlessly, demanding lightning-fast optical fiber connections. These connections are crucial not only for scaling AI infrastructure but also for replacing degrading copper connections within data centers. Lumentum is a key player in this transition.
Lumentum's Vice President of Investor Relations, Kathy Ta, highlighted the immense growth potential. Markets for AI connectivity could see a 10x expansion over existing telecom interconnects, with further multiplications possible as optical solutions become standard for scale-up and scale-in within AI clusters. This scenario suggests a potential 100x growth in the total addressable market.
Nvidia has invested $2 billion in Lumentum, signaling a close collaboration expected to benefit future AI systems. This investment underscores the strategic importance of optical fiber technology, which offers a compounding growth layer on top of the existing AI boom. Companies like Lumentum, specializing in fiber-optic lasers and modules, are well-positioned for substantial growth.
