Description
The Lenovo 4X97A81848 is a 2-meter NVIDIA NDRx2 OSFP800 to 4x HDR100 QSFP56 passive copper splitter cable designed for high-performance InfiniBand networking environments. It provides a breakout connection from a single NDRx2 OSFP800 interface to four HDR100 QSFP56 connections, supporting flexible deployment across compatible NVIDIA Quantum InfiniBand switch platforms.
Engineered for high-bandwidth AI, HPC, and data-intensive infrastructure, this passive copper cable provides a reliable, direct-connect option without requiring active optical components. It is suited for short-distance rack and cluster connectivity where high-speed performance and dense network configurations are required.
