4 Port PCIe x1 Gigabit Ethernet Network Card with RTL8111H Chip, Quad RJ45 Ports 10/100/1000Mbps PCI Express LAN Adapter for Desktop PC

This 4-port PCI Express x1 gigabit network card is equipped with four independent RJ45 LAN ports and Realtek RTL8111H high-performance control chip, offering cost-effective multi-network expansion solution for desktop PCs. It perfectly meets the demands of multi-line network access, network monitoring, soft routing and data transmission workstations.

The card adopts standard PCIe x1 interface, which can be inserted into any vacant PCIe slot of desktop motherboards without occupying large-size expansion slots. Each RJ45 copper port supports automatic speed adaptation of 10Mbps, 100Mbps and 1000Mbps, and supports full-duplex and half-duplex transmission modes to effectively reduce data packet loss and transmission delay.

It supports link aggregation, VLAN tagging and wake-on-LAN functions, greatly improving network bandwidth and transmission efficiency when transmitting large files, streaming media and batch data. The circuit board is equipped with optimized heat dissipation layout, which avoids overheating and network disconnection caused by long-time uninterrupted operation.

Gold-plated RJ45 contacts enhance corrosion resistance and signal stability, and independent signal isolation design effectively reduces electromagnetic interference between four network ports. It supports mainstream Windows and Linux operating systems, only simple driver installation is required to complete configuration.

Suitable for office multi-network desktops, monitoring hosts, small soft routing equipment and data storage workstations. Compact standard half-height bracket design fits most PC chassis, bringing flexible multi-gigabit network expansion capability to your desktop computer.
