Definition of network interface

The rapid development of the network has entered the G era, and the Gigabit network transmission equipment is no longer a new thing. However, as high-end equipment, they also have "high-end" prices. A lucent gigabit network cable imported with original packaging is 2 meters long, but it costs 100 yuan. If it is an ordinary 100 megabyte network cable, about 4 yuan is enough.

Gigabit ports are downward compatible, and can also be connected to 100m ports.

The cable clamp position of the 100m network cable crystal head is used to fix the network cable at the back end. Gigabit crystal head has been changed to another kind of cable clamp. Compared with 100m, this cable clamp has the advantages that the ring is fixed as a whole. First, it is relatively strong. Second, it will not flatten the network cable and reduce the transmission efficiency.
