Why choose it

Break through Gigabit bottlenecks with true 10 Gbps throughput. The TX401 supports multi-gig 2.5G and 5G BASE-T standards, allowing you to use existing Cat5e or Cat6 cabling for those speeds and only Cat6a for full 10G. Advanced features such as QoS, VLAN tagging, and PXE boot give IT administrators the flexibility to optimize network traffic and deploy systems remotely.

Ideal use cases

• Direct 10G connection between a desktop and a NAS for fast backups and file transfers
• High-bandwidth video editing, 3D rendering, and scientific computing
• Upgrading a small office server to handle multiple concurrent users without lag
• Low-latency gaming and streaming setups

Good to know

The adapter operates in temperatures from 0°C to 40°C and 10% to 90% non-condensing humidity. It supports PXE boot for network-based OS deployment and includes a low-profile bracket for slim cases. The Aquantia AQC107 chipset is widely compatible with major operating systems and virtualization platforms.
