Sustain high-throughput server connectivity with a dual-port 10 GbE fiber adapter built for demanding infrastructure. The AddOn QLE3242-SR-CK-AO pairs two open SFP+ ports with a PCIe 2.0 x8 host interface, giving you the bandwidth needed for storage traffic, virtualization clusters, and east-west data movement. Intel 82599 chipset support anchors the design with a widely deployed controller known for stable enterprise networking behavior. Multi-mode fiber support makes it a practical fit for short-reach data center links where SFP+ optics are already standard. The plug-in card form factor installs cleanly in server expansion slots, while the dual-port layout helps consolidate connections without adding unnecessary complexity. For teams replacing aging adapters or standardizing on a proven 10 GbE platform, this model offers a clear balance of performance, compatibility, and long-term value. Lifetime warranty coverage adds another layer of confidence for environments where network hardware is expected to stay in service for years, not quarters.
