Addressing the transmission bottlenecks of traditional Gigabit NICs, as well as the drawbacks of conventional 10 Gigabit NICs—which rely on high-end chips and PCIe X8/X16 interfaces, incur high hardware costs, impose stringent motherboard specifications making them unaffordable for ordinary users, and suffer from high power consumption and poor compatibility— The LeKuo PCIe X4 Single-Port 10GbE Optical Network Adapter (compatible with X8 and X16 slots), powered by the Realtek RTL8127 chip, enables automatic switching between 10GbE (10Gbps) and Gigabit (1000Mbps) speeds. In 10G mode, its typical power consumption is as low as 1.79W. It supports 16KB jumbo frames, PXE network boot, and Wake-on-LAN functionality. Compatible with desktops, workstations, and entry-level servers without requiring high-end motherboards, it perfectly addresses 10G network deployment needs across multiple scenarios, including SMB office environments, home NAS upgrades, and diskless workstation deployments.
Realtek RTL8127ATF Chip: Core Support for Low Power Consumption and Full-Speed Operation
The Realtek RTL8127 chip, designed as a core solution for entry-level 10 Gigabit scenarios, offers three key advantages: First, full-rate auto-negotiation capability supporting 1000M/10Gbps multi-rate switching, automatically adapting to existing Gigabit switches and future 10 Gigabit network devices without frequent NIC replacement; Second, hardware-level performance optimization integrates hardware ECC/CRC verification and data offload functions, reducing CPU utilization and ensuring stable 10G operation even on low-spec hosts. Third, an ultra-low power design achieves typical power consumption of just 1.79W in 10G mode—significantly lower than comparable 10G NICs—making it ideal for 24/7 devices like NAS systems.
SFP+ Fiber Optic Interface: Flexibly adapts to diverse transmission scenarios
The network card features a standard SFP+ fiber interface supporting hot-swappable SFP+/SFP optical modules. When paired with multimode fiber modules, it achieves transmission distances up to 550 meters, making it ideal for multi-floor cabling in small and medium-sized enterprises. With single-mode fiber modules, transmission distances extend up to 10 kilometers, suitable for small campus network coverage. This flexible interface design enables the network card to adapt to diverse transmission requirements across different scenarios, enhancing equipment utilization rates.
16KB Jumbo Frames: Significantly Enhance Large File Transfer Efficiency
The network card supports jumbo frames up to 16KB, significantly reducing packet count and frame gap overhead compared to traditional 1.5KB standard frames. When transferring large files such as engineering documents, 4K video footage, or virtual machine images, this feature reduces CPU interrupts and network latency, delivering a 15%-20% increase in large-file transfer efficiency in real-world testing. It is particularly well-suited for scenarios requiring frequent transfer of massive files, such as video studios and design firms, effectively shortening file transfer times.
Dual Practical Functions: PXE Boot + Wake-on-LAN, Reducing Management Costs
● PXE Network Boot: Supports booting operating systems over the network, enabling host startup without a local hard drive. For diskless workstation environments like school computer labs and corporate office areas, a single server can centrally deploy systems, reducing hard drive procurement costs while facilitating bulk system updates and maintenance to enhance management efficiency.
●Wake-on-LAN (WOL): Enables remote wake-up of powered-off hosts over the network. When paired with remote control software, it facilitates remote maintenance and management of devices in different locations. Ideal for enterprise servers, home NAS devices, and other equipment requiring occasional remote operations, eliminating the need for on-site power-up and reducing operational costs.
Fully compatible across all systems: Supports all major operating systems
Leveraging the robust driver ecosystem of the Realtek RTL8127 chip, the network card fully supports Windows 10/11 and Linux systems. Once installed, it reliably delivers foundational network connectivity, meeting the 10 Gigabit Ethernet requirements for virtualization scenarios.

Deployment Configuration Guide: Quick Start, Zero Technical Barrier
1. Hardware Installation Steps
1. Turn off the host power, open the chassis, and locate an available PCIe x4/x8/x6 slot.
2. Remove the corresponding chassis bracket, align the network card's gold fingers with the slot, insert it smoothly, and tighten the mounting screws.
3. Insert the appropriate SFP+ optical module (multimode/singlemode/copper) based on transmission requirements, then connect the fiber optic or copper cable to the switch.
4. Close the chassis, reconnect the power supply, and power on the system. The network card will be automatically detected (some systems may require manual driver installation).
2. Key Feature Configuration
● Enable Jumbo Frames: On Windows systems, navigate to “Device Manager → Network Adapters → Network Card Properties → Advanced → Jumbo Frame” and select “16000 Bytes”; on Linux systems, configure via command line—refer to LeKuao's official technical documentation for specific commands.
● Enable PXE Boot: Enter the motherboard BIOS, set “Network Boot” as the first boot option under “Boot Options”, save and restart.
● Enable Wake-on-LAN: On Windows systems, enable “Wake on LAN” under ‘Advanced’ in the network adapter properties and check “Allow this device to wake the computer” under “Power Management”. Configure MAC-to-IP binding for the network adapter on the router side, then send a wake-up packet using a wake-up tool.
3. Precautions
● When selecting SFP+ modules, ensure the module speed matches the network card (supports modules up to 10Gbps) to prevent incompatibility issues that could render the module unusable.
● During prolonged high-load operation, ensure adequate chassis ventilation. The network card's built-in cooling design meets standard thermal requirements; no additional fans are necessary.
