Lenovo Intel X520 2-Port 10GbE SFP Adapter | Fiber Adapter, Enterprise

Maintain high-throughput connectivity for virtualization hosts, storage traffic, and aggregation layers with Lenovo’s Intel X520 2-port 10 GbE SFP embedded adapter. Dual SFP ports give you flexible fiber uplink options while preserving PCIe resources for other expansion needs in the server. Built around Intel’s proven X520 controller family, this adapter is suited to environments that need stable 10 Gigabit performance without moving to higher-cost 25 GbE infrastructure. For infrastructure teams, the value is in consistency: dependable server-to-switch links, straightforward fiber cabling, and a form factor that fits enterprise deployment standards. It is a practical choice for upgrading legacy 1 GbE systems, segmenting traffic for application and storage paths, or adding redundant uplinks to critical hosts. When uptime and throughput both matter, this adapter helps keep the network layer aligned with the rest of the platform.
