If you are in the network communication industry, I believe you should know some Ethernet cables, such as Super Category 5 network cable, Category 6 network cable and Category 7 network cable. But do you know what the Cat8 Category 8 cable is? What is the difference between it and five types of network cables, six types/super six types of network lines, and seven types/super seven types of network cables? Here is the speed (FS) to bring you to know the new generation of network jumpers - Cat8 eight network cable.
What is the Cat8 Category 8 cable?
The Cat8 Category 8 cable is the latest generation of double-shielded (SFTP) network jumpers. It has two wire pairs and supports 2000MHz bandwidth with a transmission rate of up to 40Gb/s, but its maximum transmission distance is only 30m, so it is generally used. Connections to servers, switches, patch panels, and other devices in short-distance data centers.
Cat8 Category 8 Cable Standard
The Cat8 Category 8 cable is officially released in 2016 by the Telecommunications Regulatory Commission (TIA) TR-43 committee, as follows:
1. Compliant with the IEEE 802.3bq 25G / 40GBASE-T standard, it specifies the minimum transmission rate of Cat8 Category 8 network cables and supports 25 Gbps and 40 Gbps network cabling.
2. Compliant with ANSI / TIA-568-C.2-1, specifies the channel and permanent link for Cat8 Category 8 cable and includes resistor imbalance, TCL and ELTCTL restrictions.
3. Meets ANSI / TIA-1152-A standards and specifies Cat8 Category 8 cable field tester measurement and accuracy requirements.
4. It complies with the ISO / IEC-11801 standard and specifies the channel and permanent link of Class I/II Cat8 Category 8 cable.
Cat8 Category 8 Cable Category
In the ISO / IEC-11801 standard, Cat8 Category 8 network cables are classified into Class I and Class II according to channel level. Among them, Class I Cat8 Class 8 cable shielding types are U/FTP and F/UTP, which are backward compatible with Cat5e and Cat6. Cat6a's RJ45 connector interface; Class II Cat8 Category 8 cable shielding type is F/FTP or S/FTP, which is backward compatible with TERA or GG45 connector interfaces.
The difference between Cat8 eight types of network cable and super five network cable, six network cable, super six network cable and seven/super seven network cable.
At present, there are five types of common network cables on the market: five types of network cables, six types of network cables, six types of network cables, seven types of network cables, and seven types of network cables. What is the difference between Cat8 eight types of network cables and these network cables? ? The following is the parameter list of the Internet cable:
As can be seen from the above table, the Cat8 eight-type network cable and the seven/super seven network cable are shielded twisted pair cables, which can be applied to data centers, high-speed and bandwidth-intensive places, although the transmission distance of the Cat8 eight-type network cable is not as good. The seven/super seven network cables are far away, but their speed and frequency are far superior to those of the seven/super seven network cables. Cat8 eight types of network cable and super five network cable, six types / super six network cable between the major differences, mainly in terms of speed, frequency, transmission distance and applications.
