what is cat 8 ethernet cable？

The development of science and technology makes people overwhelmed, and the network cable has also undergone several generations of replacement, and the transmission rate has officially entered the 10 Gigabit era.

Is the 40,000-Gigabit Cat8 SFTP network cable as the highest-level existence in the current network cable field really mature? Is it already in use? Can ordinary crystal heads carry such a large transmission rate? With all kinds of doubts, we continue to look down!

what is cat 8 ethernet cable?

Cat8 ethernet cable (Cat8) is the latest generation of Cat8 SFTP network cable, which can support a bandwidth of 2000MHz and a transmission rate of up to 40Gb/s, but the transmission distance can reach its best performance within 30 meters, so it is often used for short-distance data Connection of servers, switches, patch panels and other equipment in the center.

Cat8 network cable standards

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

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

2. It complies with the ANSI/TIA-568-C.2-1 standard, specifies the channel and permanent link of the eight types of network cables, 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 eight-category network cable field tester.

4. It complies with the ISO/IEC-11801 standard and specifies the channels and permanent links of the I/II category eight network cables.

Although Cat8 network cables and Cat7/Cat7e network cables are shielded twisted pairs, they can be used in high-speed broadband environments, such as data centers and bandwidth-intensive places. Although the eight types of network cables want to achieve optimal performance during use, they are limited to within 30m, but the transmission rate and frequency bandwidth far exceed other network cables.

Advantages of the eight types of network cables

The eight types of network cables can share the RJ45 port, which means that it can easily upgrade the network speed from 1G to 10G, 25G and 40G; in addition, the eight types of network cables are also plug-and-play and can be used like other types. The network cable is terminated on site, 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 Category 8 network cables are no exception. According to market feedback, when deploying 25G/40GBASE-T networks, when the transmission distance is less than 30 meters, Category 8 cables are more cost-effective than fiber optic jumpers, so most people are still keen to use Category 8 cables.

Cat8 network cable application scenarios

In the industrial field, Category 8 network cables are generally used for short-distance data center servers, switches, distribution frames, etc., and Category 8 cables have a super shielding function, which is very suitable for shielding the wiring of computer rooms and confidential networks.

In ordinary home network cables, the typical length of the wiring is roughly the same as the range of the data center. With the application of 8K ultra-high-definition video, 5G intelligent life, and the stimulation of game enthusiasts pursuing the ultimate network experience, it will become a high-speed structured wiring. The catalyst for future broadband upgrades has reserved a lot of room for expansion.

In the 5G era, the eight types of network cables have begun to receive great attention from major operators and manufacturers. They provide a cost-effective transmission medium for network construction. With the rapid change of the network information era, they have a good market prospect and gradually become Main equipment wiring for short-distance transmission.
