The difference between several types of network cables

CAT5E super five network cable

The identification of Category 5 network cable is CAT5E. The transmission frequency is 100MHz, the transmission rate is 1000Mbps, and it supports gigabit networks.

There are 4 pairs of cables and 1 anti pull cable in the super five types of network cables.

The bare copper diameter of Class 5 network cables is 0.51mm, and the insulation wire diameter is 0.92mm. The cable diameter is 5mm.

CAT6A Super Category 6 Network Cable

The identification of Category 6 network cable is CAT6A. The transmission frequency is 500MHz, the transmission rate is 10Gbps, and it supports 10 Gigabit networks.

Category 7/Super Category 7 Network Cable CAT7

The identification of the seven types of network cables is CAT7. The transmission frequency is 600MHz, the transmission rate is 10Gbps, and it supports 10 Gigabit networks.

The identification of the super seven network cables is CAT7A. The transmission frequency is 1000MHz, the transmission rate is 10Gbps, and it supports 10 Gigabit networks.

Class 7 network cable is an 8-core shielded wire, which is different from ordinary shielded wires. In Class 7 cables, each pair of wires has a shielding layer, and the four pairs of wires together have a common large shielding layer.

Each pair has a shielding layer (usually metal foil shielding), and then there is a shielding layer (usually metal woven wire mesh shielding Braided Shield) outside the 8 cores, with the same interface as RJ-45. Total shielding+pair shielding (usually metal foil shielding), Class 7 line S/FTP Cat.7 (HSYVP-7) has a maximum transmission frequency of 600MHz, and the transmission frequency of Super Class 7 line is 1000MHz.

八类网线 CAT8

八类网线， CAT8，跟七类网线一样的是 双层屏蔽（SFTP），它拥有两个导线对，2000MHz的超高宽屏， 传输速率高达40Gb/s，但它最大传输距离仅有30m，故一般用于 短距离数据中心的服务器、交换机、配线架以及其他设备的连接。虽然八类线传输距离短， 但传输速率和频率带宽是远远超过其他类的。主要用在网络设备互联的跳线。
