Overview

The Blopobuyi 2.5G Gigabit Card PCIe x1 3.1 Wired LAN Adapter is a network card designed to add high-speed 2.5Gbps wired connectivity to desktop PCs and servers. It uses a PCIe 3.1 x1 interface, making it easy to upgrade from existing gigabit environments. With multi-rate support for 2.5G/5G/10Gbps, it is future-proof and can reduce latency in bandwidth-intensive tasks like game streaming and 4K video editing. It also supports PXE boot and VLAN tagging, making it suitable for both enterprise servers and gaming PCs.

Key Features

Multi-rate support (2.5G/5G/10Gbps): Backward compatible with existing gigabit routers, allowing gradual upgrades as network equipment improves. Enhanced security with IEEE 802.1ad VLAN tagging: Dual VLAN tagging protects critical data, and flow control technology optimizes bandwidth allocation to prevent performance drops during simultaneous connections. Stable operation with 6-layer PCB: The premium 6-layer PCB minimizes signal loss. Shock-resistant connectors and dust-proof coating ensure stable connections even in harsh environments. Optimized heat dissipation reduces temperature rise by 40% compared to conventional designs. Multi-platform compatibility: Includes drivers for UEFI/Secure Boot environments, supporting Windows 10/11 and Linux. Works well with virtualization and cloud systems. * User-friendly design: Comes with a low-profile bracket for slim PC cases.
