Introduction of CAT8 network cable

 

If you are in the network communication industry, I believe you should know some Ethernet cables, such as Category 5e network cable, Category 6 network cable and Category 7 network cable. But do you know what Cat8 eight-category network cable is? How is it different from Category 5 network cable, Category 6/Super 6 network cable and Category 7/Super 7 network cable? Let's take you to know the new generation of network jumpers-Cat8 eight types of network cables.

 

Cat8 eight types of network cable is a generation of double-shielded (SFTP) network jumper, it has two wire pairs, can support 2000MHz bandwidth, and the transmission rate is up to 40Gb/s, but its transmission distance is only 30m, so it is generally used for short The connection of servers, switches, patch panels and other equipment in the data center.

 

The relevant standards of Cat8 eight types of network cables were officially released by the TR-43 Committee of the Telecommunications Industry Association (TIA) in 2016. The details are as follows:

 

1. It complies with the IEEE 802.3bq 25G / 40GBASE-T standard, specifies the minimum transmission rate of Cat8 eight types of network cables, and can support 25 Gbps and 40 Gbps network cabling.

 

2. It complies with the ANSI/TIA-568-C.2-1 standard, stipulates the channel and permanent link of Cat8 eight-category network cable, and includes the restrictions of resistance imbalance, TCL and ELTCTL.

 

3. It complies with the ANSI/TIA-1152-A standard, which stipulates the measurement and accuracy requirements of the Cat8 eight-category network cable field tester.

 

4. It complies with the ISO/IEC-11801 standard, which stipulates the channel and permanent link of the I/II Category 8 Cat8 network cable.

In the ISO/IEC-11801 standard, Cat8 eight-category network cables are divided into Category I and II according to the channel level. Among them, the shielding types of Category I Cat8 eight-category network cables are U/FTP and F/UTP, which are backward compatible with Cat5e and Cat6. , Cat6a RJ45 connector interface; Category II Cat8 eight types of network cable shielding type is F/FTP or S/FTP, backward compatible with TERA or GG45 connector interface.

 

The difference between Cat8 Category 8 network cable and Category 5e network cable, Category 6 network cable, Category 6 network cable and Category 7/Category 7 network cable

 

Cat8 Category 8 network cables are shielded twisted-pair cables, like Category 7/Super 7 network cables. They can be used in data centers, high-speed and bandwidth-intensive places, although the transmission distance of Cat8 Category 8 cables is not as good as Category 7/Super 7 network cables. It is far, but its speed and frequency are far beyond the CAT7/Super CAT7 network cable. There is a big difference between Cat8 Category 8 network cable and Category 5e network cable, Category 6/Category 6 network cable, which is mainly reflected in the speed, frequency, transmission distance and application.
