LPO (Linear-drive Pluggable Optics) is a transceiver packaging technology. 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. Unlike traditional retimed optics that rely on Digital Signal Processors (DSPs) within the module. An LPO (Linear Pluggable Optics) solution offers considerable power savings for optical interconnect by removing the digital signal processing (DSP) function from the pluggable optical module. Unlike traditional DSP-based optical modules, LPO removes the retimer and relies on the host ASIC's native 112G PAM4 SerDes equalization to maintain signal integrity.
