Support dense 400 GbE switching with a QSFP-DD SR8 optical transceiver designed for short-reach optical links in modern data center fabrics. This module is a strong fit when you need to keep port density high and latency low across top-of-rack, leaf-spine, or intra-row connections. The QSFP-DD form factor is built for high-port-count platforms, and the SR8 optical architecture is intended for short-distance deployments where multimode connectivity is the right economic and operational choice. NVIDIA compatibility helps streamline qualification in environments centered on NVIDIA networking hardware, while TAA compliance supports public sector and other controlled procurement workflows. Choose this module when 400 GbE throughput matters more than distance and when you want to avoid overspending on long-reach optics that your topology does not require. It gives infrastructure teams a clean path to scale bandwidth inside the rack or across nearby switches without compromising on platform fit or sourcing requirements.
