First ,Do you know the classification of network cables?

There are many categories of network cables, which are divided into CAT5/CAT5E, CAT6/CAT6E and CAT7:

CAT 5 network cable: the network cable is marked with CAT 5 on the outside. The highest transmission frequency and transmission rate of the network cable are 100MHz and 100Mbps. The network cable is suitable for networks under 100 mbit/s, but it is not used anymore.

CAT5E: the network cable is marked with cat.5e on the outside. The transmission frequency of the network cable is the same as that of CAT5, but the maximum transmission rate is 1000Mbps. The network cable applies to gigabit networks.

CAT6 network cables: the network cable is marked with cat.6 on the outside. The transmission frequency and maximum transmission rate of the network cable are 250MHz and 1Gbps, which are suitable for gigabit networks.

CAT6E network cable: the network cable is marked with cat.6e on the outside. The maximum transmission frequency is 500 MHz and the transmission speed is 10Gbps. It is suitable for a 10-gigabit network

CAT 7 network cable: the latest kind of shielded twisted pair wire, the core of class 7 is about 0.57mm copper wire, is high purity oxygen free copper, which can ensure ultra-low resistance, so as to be able to transmit farther, more stable.The highest transmission frequency of the cat 7 is 600Mhz, and the transmission rate can reach 10Gbps.

Secondly ,How do I choose an internet lan cable?
