## Executive Summary
AI infrastructure networking is approaching a physical turning point as the copper links that tie GPUs together inside a rack strain under ever-faster signaling speeds. The move to light-based interconnects could redraw the boundaries of what counts as a single AI system. Cisco Systems Inc.

## Why It Matters (Strategic Analysis)
Physical copper cabling inside AI compute clusters has hit strict signaling speed boundaries, constraining GPU scale-up domains to single racks. Transitioning to 400G-per-lane pluggable optics expands the architectural boundaries of accelerated computing domains from isolated racks to row-scale deployments.
