Advantages of cable ethernet cat 8

With the development and progress of science and technology, various network cables have also undergone several generations of replacement. The transmission rate has been dramatically improved, officially entering the 10 Gigabit era.

The 40,000-gigabit cable ethernet cat 8 is the highest-level existence in the current network cable field. Is its technology mature enough? Can ordinary crystal heads withstand such a significant transmission rate?

What is cable ethernet cat 8?

Cable ethernet cat 8 is the latest double shielded (SFTP) ethernet cable generation. It can support a bandwidth of 2000MHz and a transmission rate of up to 40Gb/s. Still, its best performance can only be achieved within a transmission distance of 30 meters, so it is often used for servers in short-distance data centers: switches, patch panels, and other equipment connections.

Cable ethernet cat 8 standards

The relevant standards of Cat8 network cables were officially released by the TIA TR-43 Committee in 2016, as follows:

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

2. Complies with ANSI/TIA-568-C.2-1 standard, which specifies the channel and permanent link of Cat8 eight network cable, and includes the limitation of resistance unbalance, TCL and ELTCTL.

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

4. Compliant with the ISO/IEC-11801 standard, it specifies the channel and permanent link of the I/II Cat8 eight-category network cable.

Comparison of cable ethernet cat 8 and other network cable parameters

The difference between the eight types of cables and other types of network cables is relatively significant, mainly reflected in the transmission rate, frequency bandwidth, transmission distance, etc.

Although the Cat8 network cable and the Cat7 network cable/Cat7e network cable are all shielded twisted pair cables, they can be used in high-speed broadband environments, such as data centers and bandwidth-intensive places. Although the best performance of the eight network cables is limited to within 30m during use, the transmission rate and frequency bandwidth are far beyond those of other network cables.

The advantages of cable ethernet cat 8

Cat8 network cables can share RJ45 ports, which means that it can easily upgrade the network speed from 1G to 10G, 25G, and 40G; in addition, Category 8 network cables are also plug-and-play and can be used like other categories. The network cable is field terminated, which 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 cables are no exception. According to market feedback, when deploying a 25G/40GBASE-T network and the transmission distance is less than 30 meters, the Category 8 network cable is more cost-effective than the fiber patch cord, so many enterprises are still keen to use the Category 8 network cable.

Cable ethernet cat 8 application scenarios

Cat8 network cables are generally used for servers, switches, patch panels, etc. Cat8 network cables have a vital shielding function in short-distance data centers, which is very suitable for the wiring of shielded computer rooms and security networks.

In ordinary households, the typical length of cabling is roughly the same as that of a data center. With the application of 8K ultra-high-definition video, 5G intelligent life, and other applications and the stimulation of game enthusiasts who pursue the ultimate network experience, it will become high-speed structured cabling. It is a catalyst, which reserves excellent room for expansion for future broadband upgrades.

The structure of cable ethernet cat 8

The cables ethernet cat 8 that have been put into use include cabled network cables and finished jumpers. They use multi-strand tinned copper as conductors and are made of high-quality PVC environmental protection material, which is resistant to wear and stretch and has a long service life to ensure signal stability, as always. The finished jumper interface adopts a nickel-plated shielding shell and gold-plated three-pronged chip, which is resistant to plugging and unplugging.

In the 5G era, the cable ethernet cat 8 has attracted significant attention from major operators and manufacturers. They provide a cost-effective transmission medium for network construction. Main equipment wiring for distance transmission.
