Description
The Lenovo 4X97A81846 is a 1-meter NVIDIA NDRx2 OSFP800 to 4x HDR100 QSFP56 passive copper splitter cable designed for high-performance InfiniBand networking environments. It enables a single NDRx2 OSFP800 connection to break out into four HDR100 QSFP56 connections, supporting flexible connectivity between NVIDIA Quantum InfiniBand infrastructure.
Designed for AI, HPC, and data-intensive deployments, this passive copper cable provides a direct, high-bandwidth connection without requiring active optical components. It is compatible with select NVIDIA Quantum HDR, NDR, and XDR InfiniBand switches offered by Lenovo.
