RoHS supporting 10BASE-T, 100BASE-TX (Fast Ethernet) 1000BASE-T/1000BASE-TX (Gigabit Ethernet), 10GBASE-T (10-Gigabit Ethernet) and 25GBASE-T (40 GbE). 1.0 up to 2GHz. 【Highly 】Common RJ45 Port allows you to connect a wide variety of devices.
The result is that it considerably improves noise resistance, protection against EMI/RFI, and almost eliminates alien crosstalk (AXT). And also this could be backward compatible with Cat5e, Cat5, Cat6 and much more faster than them.
