Companies supplying high-speed optical transceivers, coherent transmission systems, and fiber networking equipment that form the physical interconnect layer for AI datacenters and hyperscaler networks. Qualifies companies with material datacenter or AI-driven optical product revenue, distinct from the broader ai_infra (GPU clusters/MLOps) and ai_data_center_infra (real estate/power) themes.

Topology Rationale
The theme is centered on the physical optical interconnect stack that links AI servers, racks, datacenters, and metro/long-haul networks. The layers therefore separate core optical system and module vendors from upstream photonic/electronic building blocks, adjacent test and integration enablers, and the cloud/AI operators whose capex and traffic growth drive demand for high-speed optics.
Value-Chain Layers
1
Optical Transport, Switching & Transceiver System Vendors
These companies sell the optical networking platforms, coherent systems, pluggables, and datacenter/telecom optical modules that directly form the AI interconnect layer.
