What is Cat8 ethernet cable?

Cat8 network cable is the latest generation of double-shielded (SFTP) network jumper, which has two wire pairs, can support a bandwidth of 2000MHz, and a transmission rate of up to 40Gb/s. In addition, the Cat8 network cable can be upwardly compatible with all RJ45 cables, and is specially designed for 25/40GBASE-T applications, but its transmission distance is short, only 30m, especially suitable for servers, switches, and wiring in short-distance data centers Racks and other equipment connections.

The standard of Cat8 eight types of network cables

The relevant standards of the Cat8 eight-category network cable were officially released by the TR-43 Committee of the American Telecommunications Industry Association (TIA) in 2016, as follows:

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

2. Conforms to the ANSI/TIA-568-C.2-1 standard, which specifies the channel and permanent link of Cat8 network cable, and includes the restrictions of resistance unbalance, TCL and ELTCTL.

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

4. It complies with the ISO/IEC-11801 standard, which specifies the channels and permanent links of Category I/II Cat8 network cables.

Category of Cat8 eight-category ethernet cable

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

Advantages of Cat8 Ethernet cable

As mentioned above, Cat8 network cables can share RJ45 ports, which means that Cat8 network cables can easily upgrade the network rate from 1G to 10G, 25G and 40G; in addition, Cat8 network cables are also plug-and-play Ready-to-use and field-terminated like other types of network cables, it is very easy to deploy.

At the same time, due to the low cost of network cables, twisted pair cables have always been the most cost-effective solution in Ethernet, and Cat8 ethernet cables are no exception. Therefore, when deploying a 25G/40GBASE-T network, when the transmission distance is less than 30 meters, Cat8 network cables are more cost-effective than fiber jumpers, and when the transmission distance is less than 5 meters, Cat8 network cables are more cost-effective than twisted pair cables. High-speed cables are more cost-effective.

The difference between Cat8 ethernet cable and Cat5e ethernet cable, Cat6a ethernet cable, Cat6 ethernet cable and Cat7 ethernet cable

At present, there are five types of network cables that are common on the market: Cat 5e, Cat 6, Cat 6, Cat 7 and Cat 7. So what is the difference between Cat8 and these cables? ? The following is the parameter table of the above network cable:

As can be seen from the above table, Cat8 network cables, like Category 7/super seven network cables, are shielded twisted pair cables, which can be used in data centers, high-speed and bandwidth-intensive places, although the transmission distance of Cat8 network cables is not as good as Category 7/Category 7e network cable is far away, but its speed and frequency are far higher than Category 7/Category 7e network cable. There is a big difference between Cat8 network cable and Category 5e network cable, Category 6/Category 6 network cable, which is mainly reflected in speed, frequency, transmission distance and application.

Although Cat8 network cables are not widely used at present, as network cabling has higher and higher requirements for transmission performance, it is believed that Cat8 network cables will gradually become the mainstream product of the data center integrated wiring system in the future.
