LPO modules cut per-port power by up to 50% compared to DSP-based optics, enabling denser fabrics and lower rack-level OPEX. Ideal for hyperscale, cloud, and enterprise AI deployments where every watt and degree matters. To address this, Macom and NVIDIA first proposed Linear-drive Pluggable Optics (LPO) in 2022. The idea is simple: instead of a DSP (digital signal processor) inside the module – replacing it with transimpedance amplifier (TIA) and a driver chip with high linearity and EQ capability – LPO shifts signal processing into. having tripled in the past decade. According to the 2024 Report on U. S Data Center Energy Use, published by the Lawrence Berkeley National Laboratory, data centers account for 4. 4% of total electricity consumption in the U. in 2023, and are projecte to increase to 6. By shortening the electro-optical conversion path and improving bandwidth density and energy efficiency, they are redefining the system. Enter LPO (Linear Pluggable Optics) — a low-power alternative that offers dramatic energy savings and cooling benefits while keeping up with the relentless speed of today's AI clusters.
