What is the Cat8 Category 8 network cable? What is the difference with Cat5, Cat6, and Cat7 network
If you are in the network communication industry, I believe you should know some Ethernet cables, such as Super Category 5, Category 6 and Category 7 and so on.
But do you know what Cat8 Category 8 network cable is?
What is the difference between it and Category 5, Category 6 / Super Category 6 and Category 7 / Super Category 7?
The following will take you to know the new generation of network jumpers-- Cat8 eight types of network cables.
What is the Cat8 Category 8 network cable?
Cat8 Category 8 network cable is the latest generation of double shielded (SFTP) network jumper, it has two wire pairs, can support the bandwidth of 2000MHz, and the transmission rate is as high as 40GbUniverse, but its maximum transmission distance is only 30m, so it is generally used for the connection of servers, switches, distribution frames and other equipment in short-distance data centers.
The standard of Cat8 Class 8 network cable.
The relevant standards for Cat8 Category 8 network cables were officially issued by the (TIA) TR-43 Committee of the American Communications Industry Association in 2016, as follows:
1. Conforms to the IEEE 802.3bq 25G / 40GBASE-T standard and specifies the minimum transmission rate of Cat8 Class 8 network cables, which can support 25 Gbps and 40 Gbps network wiring.
2. Conforms to the ANSI / TIA-568-C.2-1 standard, specifies the channels and permanent links of Cat8 Class 8 network cables, and includes resistance imbalance, TCL and ELTCTL restrictions.
3. Conforms to the ANSI / TIA-1152-A standard and specifies the measurement and accuracy requirements of the Cat8 eight types of network cable field tester.
4. Conforms to the ISO / IEC-11801 standard and specifies the channels and permanent links of I/II Class Cat8 Class 8 network cables.
Categories of eight types of Cat8 network cables.
In the ISO / IEC-11801 standard, according to the channel level, Cat8 Class 8 network cables are divided into Class I and II, in which Class I Cat8 Class 8 network cable shielding types are U/FTP and RJ45 UTP, which are backward compatible with Cat5e, Cat6 and Cat6a RJ45 connector interfaces; II Class Cat8 Class eight network cable shielding types are F/FTP or SF/FTP FTP, which can be backward compatible with TERA or GG45 connector interfaces.
At present, there are five common types of network cables in the market: Super Category 5 cables, Category 6 cables, Category 6 cables and Category 7 / Category 7 cables. What are The difference between Cat8 Class 8 Network Cable and Super Category 5 Network Cable, Category 6 Network Cable, Super Category 6 Network Cable and Category 7 / Super Category 7 Network Cable. ?
Although Cat8 Class 8 network cables are not widely used at present, with the increasing requirements of network cabling for transmission performance, it is believed that Cat8 Class 8 network cables will gradually become the mainstream product of data center integrated cabling system in the future.
Can provide a full set of network jumper customization services, including color, specifications, materials, length, etc.; all network cables have been strictly tested before leaving the factory to ensure smooth connection and provide you with high-quality network cables.
There are many kinds of network cables. at present, the widely used network cables are mainly divided into four categories: Cat5e super five network jumpers, Cat6 six network jumpers, Cat6a super six network jumpers and Cat7 seven network jumpers.
Next, I will introduce the Cat5e/Cat6/Cat6a/Cat7 network cable series in detail for you.
Cat5e network jumper.
Cat5e Super five shielded (FTP) network jumpers, card channel design, blue, PVC.jpg.
Compared with Category 5 jumpers, Super Category 5 network jumpers have the advantages of low attenuation, low crosstalk, higher attenuation crosstalk ratio ((ACR)), signal-to-noise ratio (SNR) and smaller delay error.
The maximum bandwidth of super Category 5 lines is 100MHz, and the wire diameter is standard 24AWG, which is suitable for gigabit Ethernet networks.
Cat6 network jumper.
The transmission performance of six types of network jumpers is much higher than that of more than five standards, which is most suitable for gigabit network transmission applications.
Compared with the super-five network lines, the performance of Category 6 network hopping is better than that of the super-Category 5 network lines in terms of crosstalk and echo loss, and the excellent echo loss performance is extremely important for high-speed network applications.
The transmission bandwidth of type 6 network jumpers is 250MHz.
