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. The transmitter uses a high-linearity driver chip to directly drive the optical modulator, converting the electrical signal into an optical signal. 125 GBd PAM4 optical interfaces, optical links using standard single-mode fiber with up to 500 m reach, and host-module electrical interfaces for hosts with DSP based SerDes and RS(544,514) FEC. It. Fully-retimed optics are traditional optical modules designed to ensure the highest levels of signal integrity and performance. That is, these optics operate with two DSPs. 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.
