Category 8 cabling is called the next generation of twisted pair copper cabling. Cat.8 is a type of Ethernet cabling solution that is designed to provide high-speed data transmission over short distances. It is the latest and fastest category of twisted-pair copper cabling and supports data rates of up to 40Gbps at distances of up to 30 meters (98 feet).
Cat8 cables are backward compatible with previous Ethernet standards such as Cat5e, Cat6, and Cat7. It uses a modified RJ45 connector that is designed to support the higher data rates and is typically used for data center applications, high-performance computing, and other enterprise-level network environments.
The relevant standards of Cat 8 network cables were formally approved by the United States Telecommunications (TIA) TR-42.7 Copper Cabling Subcommittee in 2016, the Cat 8 cabling specification (TIA 568 C.2-1), as follows:
- It complies with the IEEE 802.3bq 25G / 40GBASE-T standard, specifies the minimum transmission rate of Cat8 cables, and can support 25 Gbps and 40 Gbps network cabling.
- It complies with the ANSI/TIA-568-C.2-1 standard, stipulates the channel and permanent link of Cat8 cables, and includes the restrictions of resistance imbalance, TCL and ELTCTL.
- It complies with the ANSI/TIA-1152-A standard and specifies the measurement and accuracy requirements of the Cat8 cable field tester.
- It complies with the ISO/IEC-11801 standard, which stipulates the channel and permanent link of the I/II Category 8 cable.
See bellow category cabling standards, you will find that the category 8 cabling is a huge improvement in the performance!
Only applicable in data centers
The target market of CAT 8 is the edge application of the data center, and the copper cable connection between the server and the switch. Carry the emerging 25 and 40 GB/s rate. Although SFP+ and QSFP+ cables can support such a high -speed connection between switches and servers. However, these cables have a distance limit and are limited to about 5 to 7 meters. Because the CAT 8 supports a 30 -meter transmission distance, it is very suitable for the edge switch to be connected at the end of the column or the middle position. Because the CAT 8 shares the same connector and can be automatically negotiated with existing business technology, it is very interactive with these technologies.
By now, all Cat 8 accessories have basically been developed. Cat 8 bulk cable, Cat 8 modular patch panel(empty), which are actually the same shielded patch panels as Cat 6, Cat 8 modular jack, Cat 8 modular plug and Cat 8 patch cords. As one of more than 15 years experienced professional network patch cords manufacturers, COMNEN have been developing the category 8 patch cable when the cat8 standards approved in 2016. We spent almost 2 years to design the category 8 cable and calculate the data of how to build this 40G cable.
The primary advantage of Cat8 cabling is its ability to support higher bandwidths and faster data transmission rates than previous Ethernet standards, making it ideal for high-performance data centers, cloud computing, and other applications that require fast, reliable connectivity. However, Cat8 cabling is also more expensive than previous Ethernet standards and is generally only necessary for specialized applications that require the highest levels of performance.
