NVIDIA/Mellanox (Ethernet) Compatible 400G QSFP112 DR4 1310nm 500m PAM4 DDM MPO/MTP-12 APC SMF Linear-drive Pluggable Optics (LPO) Transceiver
The Q112-400LPO-DR4 is a cost-effective module with high performance, which is optimized for AI Datacenter, supporting data-rate of 4x112Gb/s PAM4 Optical interface and 4x112Gb/s PAM4 Electrical interface. Its transmission distance is up to 500m on single mode fibers. It replaces a retimed DSP data path with a linear data path, thus realizing lower power consumption and latency.
In large-scale AIDC deployments, LPO technology eliminates the DSP chip from optical modules, significantly reducing system power consumption and latency while improving energy efficiency.
Q112-400LPO-DR4 adopts a DSP-free linear architecture, reducing power consumption by approximately 50% (4.5W vs. 9.5W) compared with conventional 400G retimed optics. This simplified design reduces transmission latency and improves link efficiency, while also optimizing TCO through reduced cooling, power consumption, and infrastructure requirements. Designed for large-scale AI training clusters, it offers broad compatibility with mainstream RoCE devices for stable and efficient deployment.
