Add a 2.5 Gigabit RJ45 Ethernet interface to a desktop computer, workstation, or compatible server with a PCIe 2.1 x1 expansion slot. The TP-Link Omada TX201 supplies one 2.5GbE port for faster transfers to network storage, 2.5GbE switches, and other multigigabit-capable endpoints. It also negotiates with 1 Gigabit, 100 Mbps, and 10 Mbps Ethernet equipment, allowing the card to remain useful while network infrastructure is upgraded. The PCIe x1 host connection fits systems with an available compatible expansion slot without requiring a larger PCIe lane allocation. Integrated Quality of Service functions prioritize network traffic where congestion can affect streaming media, interactive applications, or large concurrent transfers. The single RJ45 interface uses standard twisted-pair Ethernet cabling, avoiding the need for a fiber transceiver or a separate media converter at the host. Both a full-height bracket and a low-profile bracket are included, supporting installation in conventional desktop towers and low-profile chassis. Driver support covers Windows 7 through Windows 11, Windows Server 2008 R2 or later, and Linux. This model is distinguished by its 2.5GbE copper port, PCIe 2.1 x1 interface, compact add-in-card format, and bracket options for different chassis profiles.
