Add a 10 Gigabit RJ45 network interface to a desktop workstation, tower server, or compact system with an available PCIe 3.0 x4 slot. The TP-Link Omada TX401 uses a single copper Ethernet port to connect directly to 10 GbE switches, network-attached storage, and other RJ45 network equipment. It also negotiates 5 Gbps, 2.5 Gbps, 1 Gbps, and 100 Mbps links when connected infrastructure operates below 10 Gigabit speed. The PCIe 3.0 x4 host connection supplies the bandwidth needed for high-throughput local traffic such as large file copies, backup jobs, media editing workflows, and access to shared storage. Integrated Quality of Service functions prioritize latency-sensitive traffic, including gaming and media streams, when multiple applications share the network connection. The RJ45 interface supports copper Ethernet deployments without requiring an optical transceiver or fiber patch cable. Installation hardware supports both standard full-height chassis and low-profile systems. A Cat 6a Ethernet cable is included for a suitable 10 Gigabit copper connection, while the low-profile bracket lets the adapter fit compact PCs and short expansion-slot enclosures. Windows, Windows Server, and Linux compatibility makes the adapter suitable for workstations and servers that need a single high-speed copper uplink.
