INSIGHT

Network Is The Data Center Roadmap

Data center networking is the "roads" that move data between logic, storage, and users.
Without advanced cables, transceivers, and switches, AI clusters cannot function effectively.

INSIGHT

Copper Versus Fiber Roles

Copper handles short-distance electrical signaling while fiber optics carry light for longer runs.
Choose copper for short, cost-sensitive runs and fiber for distances exceeding a few meters up to 100+ meters.

Market Size: Logic Vs Optoelectronics

Logic sales (CPUs/GPUs) grew >20% in 2025 and may approach $400B in 2026 per WSTS.
Optoelectronics is smaller (~$42B) but growing and crucial for AI networking.

The AI supercycle is expanding beyond just GPUs. In our first episode of the 2026 series, we break down the critical infrastructure that acts as the "roads and freeways" for data: data center networking, optics, and silicon photonics. Logic chips (like CPUs and GPUs) are the "office" where work gets done, but the network is the "commute" that moves that data. Without advanced cabling, transceivers, and switches, AI clusters simply cannot function. Find out what companies are involved in this fast growing market and how to approach investing in them.
