Features: 1.High-quality master control. Adopt for Raychem RTL8111G high-performance master control dual chip, one for each RJ45 interface, stable performance and good compatibility. 2.The imported alloy heat sink can effectively discharge excess heat, so that the network card is always at normal temperature and the operation is stable. 3.The filter can stably handle the filtering cable interference and extend the transmission distance of the network cable. 4.With thick gold fingers, the contact is more reliable, the transmission is more stable, and it is not easy to cause packet loss and distortion. It can be easily inserted and removed for thousands of times, and the PCI-E slot can be used. 5.Compatible with LEEEE802.3, 803.ab, 802.3u, 802.3x, 802.1, VLAN technology 10MB/100MB/1000MB network adaptive automatic cross detection and correction support. specification: 1.
