Description
The Lenovo 4X97A81828 is a 1.5-meter NVIDIA NDRx2 OSFP800 to 2x NDR OSFP400 passive copper splitter cable designed for high-performance InfiniBand networking environments. It provides a breakout connection from an NDRx2 OSFP800 interface to two NDR OSFP400 connections, supporting scalable, high-bandwidth connectivity for NVIDIA Quantum-based AI and HPC infrastructures.
Designed for compatible NVIDIA Quantum NDR and XDR switches, this passive copper cable provides a reliable short-distance interconnect without requiring active optical components. It is suitable for dense data center deployments where high-speed connectivity, efficient cabling, and compatibility with NVIDIA InfiniBand infrastructure are essential.
