Amphenol's QSFP-DD Linear Pluggable Optical (LPO) Transceiver delivers low-latency, high-bandwidth PCIe ® Gen 5. 0 over optical link, enabling scalable server disaggregation and efficient rack-to-rack interconnects ideal for AI/ML and rack-scale data center expansion. ptics (CPO) have been proposed. 1 shows the typical block diagram of a pluggable transceiver consisting of on-board lasers, optics, a Photonics die housing the modulator, the photodetector, and associated photonic components required for the optical path, an Electrical IC with the. Linear Pluggable Optics (LPO) are a new optical transceiver 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. 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. The focus is on 400G and 800G LPOs using 56GBd lanes.
