Dual MCIO 8i to dual PCIe x16 riser card for GPU and switch expansion.
Expanding high-bandwidth PCIe connectivity in dense server chassis often requires flexible cabling solutions to bridge motherboard interfaces with accelerator cards. The LRFN9A22 addresses this by converting dual MCIO 8i inputs into dual PCIe x16 mechanical outputs, facilitating seamless integration of GPUs and PCIe switches.
Featuring two 56G PCIe 5.0 MCIO 8i inputs, this adapter ensures maximum data throughput for demanding AI and HPC workloads. The inclusion of a dedicated GPU power connector supplying 12V via ATX Minifit ensures stable operation for high-power devices, eliminating the risk of under-powering critical components.
Ideal for data center servers requiring PCIe Gen5 expansion, the LRFN9A22 supports x8 electrical mode per cable for versatile deployment. Its robust 85 Ohm ultra-low loss PCB design guarantees signal integrity, making it a reliable choice for enterprise-grade hardware scaling.
Supports 56G PCIe 5.0 speeds with high-quality Amphenol SMT slots for reliable high-bandwidth connections.
Features two MCIO 74-pin host connectors to expand connectivity from motherboard or backplane interfaces.
Includes ATX Minifit 5569 connector providing 12V power directly to connected GPU or accelerator cards.
Can operate in x8 mode per cable, allowing versatile deployment with switches, retimers, or other PCIe devices.
High-quality optical modules and cables for optimal compatibility with your network adapter.
