Home / High-cost high-speed optoelectronic connection LPO
LPO, short for Linear Pluggable Optics, is designed to simplify the optical module architecture by removing traditional DSP chips. Instead of relying on heavy onboard digital signal processing, LPO transfers more signal compensation work to the switch ASIC. While copper cabling still offers cost and reliability advantages for short-distance connections, it faces the dual challenges of speed bottlenecks and cabling complexity in high-bandwidth, long-distance, and high-energy-efficiency scenarios. FEC (Forward Error Correction), DSP (Digital Signal Processing), CDR (Clock and Data Recovery), DRV (Driver), TIA (Trans-Impedance Amplifier), TOSA (Transmitter Optical Sub-Assembly), and ROSA (Receiver Optical Sub-Assembly). 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.
