Description
The Lenovo 4X97A81845 is a 10-meter NVIDIA active optical splitter cable designed to connect an NDRx2 OSFP800 interface to two HDR QSFP56 connections. Built for high-performance NVIDIA InfiniBand environments, it provides a reliable optical connectivity option for AI, HPC, and data-intensive networking deployments.
This cable is compatible with select NVIDIA Quantum InfiniBand switches, including QM8700, QM8790, QM9700, QM9790, and Q3200-RA platforms. Its active optical construction supports longer-distance, high-bandwidth interconnects while simplifying high-density fabric deployments.
