AI Data Center Shift: LPO Addresses Power, Puts Pressure on NVLink

The growing adoption of linear optics, specifically Linear Pluggable Optics (LPO), marks a pivotal shift in AI data center architecture, directly targeting the escalating power, cost, and thermal challenges of scaling massive GPU clusters. As models and datasets grow, the power consumption of optical interconnects—up to 30% of system power—has become an unsustainable bottleneck. LPO fundamentally alters the equation by offloading signal processing from the optical module back to the host ASIC
