Key benefits - Faster networking without major hardware changes: adds a single onboard 2.5G Ethernet port while using only a 1-lane PCI Express connection, delivering higher throughput for file transfers, backups, and streaming. - Broad compatibility and reliable link setup: the integrated 10/100/1000M/2.5G transceiver supports multiple speeds, and auto-negotiation with extended next-page functionality ensures stable connections and graceful fallback when needed. - Low system impact: requires only a 1-Lane PCI Express bus (2.5/5Gbps), so it works in systems with limited PCIe lanes and preserves bandwidth for other components. What it does (features and performance) - Supports a 1-Lane PCI Express bus at 2.5 or 5 Gbps for efficient host interface. - Onboard single 2.5G network port with an integrated 10/100/1000M/2.5G transceiver for native multi-speed Ethernet. - Operates in 2.5G, 1G Lite, and 100M modes to match network equipment and cable limitations. - Auto-negotiation with extended next-page functionality to negotiate the best possible link and maintain compatibility with a wide range of switches, routers, and NICs. Who should consider it - Users upgrading older desktops or small form-factor systems that have spare PCIe x1 slots and need faster-than-gigabit networking without replacing the motherboard. - Small offices and home users who want improved LAN performance for media streaming, large file transfers, or local backups. - Integrators building compact NAS, media servers, or edge devices that require a single reliable 2.5G connection while minimizing PCIe lane usage. Key attributes - Function: single-port 2.5G Ethernet interface with multi-rate transceiver. - Compatibility: works over a 1-lane PCI Express bus and with standard 10/100/1000M/2.5G Ethernet equipment. - Performance: supports 2.5G native speed, 1G Lite and 100M fallback; reliable link establishment via auto-negotiation with extended next-page. - Footprint: onboard single-port design suitable for systems with limited expansion slots. Typical use scenarios - Upgrade a desktop or mini-PC to 2.5G LAN for faster transfers to a 2.5G-capable NAS. - Improve streaming and collaborative work in a small office by adding a higher-speed uplink without changing existing switches. - Add a compact 2.5G network interface to a media server or edge device where PCIe lanes are scarce.
