Keep short-reach fabric links fast and orderly with the NVIDIA MMA1T00-HS HDR QSFP56 SR4 transceiver. Designed for high-density data center environments, it uses an MPO connector and multimode fiber to support short-distance optical runs up to 100 m. That makes it a strong fit for leaf-spine fabrics, switch interconnects, and other tightly packed infrastructure where clean cable routing matters. QSFP56 form factor support helps preserve port density while aligning with modern high-speed Ethernet architectures. SR4 optics are well suited to environments that prioritize efficient rack-scale connectivity over long-haul reach, giving teams a practical path for scaling bandwidth without overbuilding the optical layer. This module is also listed as NCNR, which is important for procurement planning when supply continuity and order commitment matter. For teams standardizing on dense multimode optics, it offers the reach, connector style, and form factor needed to keep high-speed links consistent across the fabric.
