Move 400 GbE traffic with an OSFP DR4 optic built for NVIDIA-compatible deployments. This module is aimed at data center teams that need high-speed short-reach connectivity without compromising port density or platform alignment. OSFP packaging supports modern high-bandwidth switch designs, while the DR4 optical architecture is suited to multimode links inside the rack or across nearby rows. The value here is operational clarity. Instead of treating optics as interchangeable, this module is positioned for environments where transceiver form factor, switch compatibility, and link speed all affect deployment risk. That matters in leaf-spine fabrics, GPU clusters, and aggregation layers where a single port can carry a large share of east-west traffic. For enterprise buyers, this is the right class of optic when you need to standardize on 400 GbE and keep the network ready for sustained throughput. It is a premium fit for teams that would rather specify the right module once than absorb the cost of rework later.
