Features: Equipped with the RT8127AF chip, it delivers an exceptionally data transfer rate of up to 10Gbps. This represents ten times the speed of Gigabit networks, enabling instantaneous transfer of large files and providing robust performances for 4K/8K video editing, large-scale servers, and data centres. Featuring an SFP+ fibre for opt data transmission, it inherently resists electromagnetic interferences, ensuring stable delivery with minimal latency. Compatibles mainstream PCIe 4X port, supports multiple operating systems. Most systems automatically detect and install driver for plug-and-play functionality. The chip incorporates metal heat sink, accelerating heat dissipation to prevent performances degradation or disconnections during prolonged high-load operating.
