Take you to know what is CAT8 Category 8 network cable? How it differs from CAT5, CAT6 and CAT7.

Take you to know what is CAT8 Category 8 network cable? How it differs from CAT5, CAT6 and CAT7.

We are in the intelligent weak power integrated wiring system, the ultra-five network cable, category six network cable and category seven network cable is certainly the most used and very familiar, but do you know what is CAT8 category eight network cable? What is the difference between CAT5, CAT6, CAT7 cable?

CAT8 Category 8 cable is what?
CAT8 Category 8 cable is the latest generation of double-shielded (SFTP) network patch cable, which has two pairs of wires, can support 2000MHz bandwidth, and transmission rates up to 40Gb / s, but it is the maximum transmission distance is only 30m, so it is generally used for short-distance data centres, servers, switches, routers, distribution frames, and other equipment connections.

CAT8 Category 8 cable standard

The relevant standards of CAT 8 Category 8 network cable were officially released by the TR-43 committee of the Telecommunications Industry Association (TIA) in 2016, as follows:

1, in line with the IEEE802.3bq25G/40GBASE-T standard, which specifies the minimum transmission rate of CAT8 Category 8 network cable, which can support 25Gbps and 40Gbps network cabling.

2、Conforms to ANSI/TIA-568-C.2-1 standard, which specifies the channel and permanent link of Cat8 Category 8 network cable, and includes the limitations of resistance imbalance, TCL and ELTCTL.

3. Conforms to ANSI/TIA-1152-A standard, which specifies Cat8 Category 8 network cable field tester measurement and accuracy requirements. Conforms to ISO/IEC-11801 standard, which specifies the channels and permanent links of Cat8 Category 8 network cables of Category I/II.

Categories of CAT8 Category 8 network cables

In the ISO/IEC-11801 standard, according to the channel level of CAT8 Category 8 network cable is divided into Category I and Category II, of which Category I CAT8 Category 8 network cable shielding type for the U/FTP and F/UTP, can be backward compatible with CAT5E, CAT5, CAT6, CAT7 RJ45 interfaces; Category II CAT8 Category 8 network shielding type for F/FTP and S/FTP which are backward compatible with TERA or GG45 interfaces.

CAT8 Category 8 network cable of the three structures

Category 8 network cable first structure: each pair of shielding + aluminium foil total shielding + outer being.

The second structure of CAT8 cable: each pair of shield + braided total shield + outer cover

The third structure of CAT8 cable: each pair of shielding + aluminium foil total shielding + braided total shielding + outer cover.

The difference between CAT8 Category 8 cable and Cat5E, Cat6, Cat6A, Cat7 cable.


Currently in the integrated wiring system, we commonly used network cable CAT5E, CAT6, CAT6A, CAT7 these kinds of CAT8 category network cable with less.

 

  • Category 5e (CAT5e): Supports network speeds up to 1000Mbps with a maximum transmission distance of 100 meters and operates at a frequency of 100MHz. It has 4 twisted pairs and is commonly used for basic networking.

  • Category 6 (CAT6): Also supports speeds up to 1000Mbps, but with a higher frequency of 250MHz, allowing for improved performance over CAT5e. The maximum distance and the number of twisted pairs remain the same, with the cable suitable for general office and home use.

  • Category 6a (CAT6A): Steps up performance to support network speeds of 10Gbps up to 100 meters, operating at a frequency of 500MHz. It has 4 twisted pairs and offers better crosstalk protection, making it ideal for industrial and business applications.

  • Category 7/7a (CAT7/CAT7A): Provides network speeds of 10Gbps up to 100 meters and operates at a frequency of 1000MHz. It has 4 twisted pairs and features even more stringent crosstalk protection, suitable for data centers and server rooms.

  • Category 8 (CAT8): Delivers the highest performance with network speeds of 25Gbps up to 30 meters and 40Gbps for shorter distances, operating at a frequency of 2000MHz. This category has 2 twisted pairs and is designed for professional and high-performance environments.

CAT8 Category 8 cable and seven / super seven network cable, are shielded twisted pair cable, can be used in data centres, high-speed and bandwidth-intensive places, although the CAT8 Category 8 cable transmission distance is not as far as the seven / super seven network cable, but its rate and frequency is far more than the seven / super seven network cable.CAT8 Category 8 cable and super five network cable, category six / super six network cable between the larger differences The difference between CAT8 cable and Super Category 5 cable, Category 6/Super Category 6 cable is greater, mainly in the rate, frequency, transmission distance and applications.
