LPO, NPO, and CPO are optical interconnect technologies designed to address bandwidth, power efficiency, and latency challenges in AI and HPC data centers as they scale beyond traditional electrical solutions. LPO (Linear-drive Pluggable Optics), proposed by Macom and NVIDIA in 2022, eliminates DSP chips for direct analog signal processing, reducing power consumption by 30–50% and latency while lowering costs.
Micron announced a 512GB DDR5 server module enabling up to 12TB memory in two-socket servers, with volume production planned for H2 2027. The module uses 60% less power than four smaller modules, offering a way to increase server memory without exceeding power budgets. This represents a potential long-term growth opportunity for Micron beyond HBM as AI inference demands expand.
