## Long description

Equip your computer with a 2.5Gbps PCIe network adapter that supports the 2.5GBASE-T (802.3bz) standard. The adapter delivers multi-gigabit wired Ethernet performance over standard Cat5e or higher cables, maintaining theoretical speeds up to 2.5Gbps at cable runs up to 100 meters (328 ft).
Advantages
The PCIe 2.5Gbps adapter enables faster local network transfers and smoother high-bandwidth tasks compared with 1Gbps interfaces. It is backward compatible with existing Ethernet networks and works over commonly installed Cat5e, Cat6 or better cabling without requiring fiber. The compact PCIe form factor allows easy installation into desktop systems.
Key specifications
Standard: 2.5GBASE-T (IEEE 802.3bz)
Maximum theoretical speed: 2.5 Gbps
Compatible cabling: Cat5e or higher
Maximum cable length: 100 m (328 ft)
Interface: PCIe (desktop add-in card)
How to use
Power off the PC, open the case and insert the adapter into an available PCIe slot. Secure the card, close the case and boot the system. Install any required drivers provided by the manufacturer or through the operating system to enable 2.5Gbps operation. Connect the adapter to your network switch or router using Cat5e or better cable, ensuring the remote device also supports multi-gigabit speeds for full 2.5Gbps throughput.
Рекомендации
For optimal performance, use quality Cat5e or Cat6 cables and verify that switches, routers or other network endpoints support 2.5GBASE-T. When upgrading from 1Gbps, confirm drivers are up to date and test throughput with appropriate network tools.
