LPO Series — EU-Tested Low-Power Optical Transceivers Next-generation 400G and 800G modules for data centers, AI clusters, and telecoms — validated in a European lab, ready to ship from Europe. 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. 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. This architecture takes advantage of the capabilities in each segment of the link to form a power, cost. Data Recovery (CDR) in the system. Instead, the signal regeneration and signal equalization that are typically performed by the DSP are split between the swi ch ASIC, the driver IC and the TIA. Some of the key proponents of LPO in the indust y are Macom, Semtech and Maxlinear. The main advantages. The STC-40027 from Swedish Telecom Opto's LPO Series is an advanced 800 Gb/s OSFP SR8 optical transceiver designed for short-reach, high-density data-centre and AI fabric applications. Leveraging Linear Pluggable Optics (LPO) technology, this module achieves exceptional power efficiency by removing. Linear Drive Pluggable Optics refers to the use of direct-drive linear technology in fiber modules.
