Lenovo IBM PCIe3 4-Port 10Gb SFP+ SR Adapter | Enterprise

Increase server-side network density without adding external hardware. The Lenovo IBM PCIe3 4-port 10Gb SFP+ SR adapter delivers four high-speed fiber ports from a single PCIe expansion slot, making it a strong fit for environments that need more connectivity per server and less cabling across the rack. This adapter is well suited to virtualization clusters, storage nodes, and application servers that carry multiple traffic classes at once. With 10Gb SFP+ SR connectivity, it supports short-reach fiber deployments commonly used inside data centers, where low-latency links and consistent throughput are essential. For infrastructure teams standardizing on Lenovo and IBM-branded components, this adapter supports procurement consistency and platform alignment. It is the kind of part that earns its place in higher-value server builds: more ports, cleaner topology, and fewer compromises when a single host must handle multiple network roles.
