Features: brand new and high quality This dual-electrical 2.5G Ethernet network adapter can provide a 2.5 Gigabit Ethernet network faster than a Gigabit network, support high-performance dual-channel networks and full-duplex communication to achieve speeds of up to 2500 Mbps and fast transmission Speed, for existing Ethernet. It is committed to providing solutions for upgrading 2.5G networks for some gaming users who do not need to use 10 Gigabit ports but cannot satisfy Gigabit network ports. Equipped with two standard RJ45 network ports, the data transmission rate is up to 10/100/1000M/2.5Gbps. It provides a 2.5 Gigabit Ethernet network that is 250% faster than the Gigabit network speed, which can improve the efficiency of internal data transmission and processing in the enterprise, and it can also increase the speed of transferring files between multiple network devices in the home for general users. This will also make the increasingly popular network video transmission smoother, and is mainly designed to increase the speed requirements of users in e-sports games. The aluminum heat sink design is used to increase the heat dissipation area, which can effectively reduce the chip temperature quickly and avoid unstable data transmission due to high temperature and overheating. It is widely used in industrial computer, embedded computer, single board computer, digital multimedia and other network equipment. Applicable operating systems include Microsoft- for Windows, Linux and for Mac OS, etc. PCIe x1 interface design, suitable for PCI for Express x1, x4, x8, x16 slots. Not applicable to PCI slots. Short iron pieces are delivered, and can be used in large and small cases. Specifications: Main controller: for Intel PCE8125B Bus type: PCIe Media interface: RJ45 Transmission rate: 10/100/1000Mbps, 2500Mbps Note: Due to the problems of lighting effects and shooting angles, there will be certain tolerances in the product, please understand.
