Eight categories of network cable six cable What difference does it make?
HTTP: // www.owire.cn/news/414.html all kinds of differences.
Eight categories of line (CAT8): currently the only has the definition of the seven types of lines, in 1999 developed the US Siemon has announced the development of eight categories of line under the trademark "Tera", eight categories of line nicknames have "tera "," 10Gip "," tera dor " and" megaline 8 "and so on. Cat8 eight types of cable shield is the latest generation of bis (SFTP) of the patch cords , it has two pairs of wires, can support the bandwidth of 2000MHz, and the transmission rates of up to 40Gb / s, the maximum transmission distance of 30m only, it is generally used for short connecting the server from the data center, switches, patch panels and other devices that can handle Terrestrial TV, DAB ,, CCTVIR control, 10/100 and 100/1000 Ethernet, video, telephony, USB peripherals.
Standards Cat8 eight categories of cable TR-43 committee officially released by the Telecommunications Industry Association (TIA) in 2016, as follows:
1. Compliance with ANSI / TIA-568-C.2-1 standard specifies eight categories Cat8 cable channel and permanent link, and comprising a resistive imbalance, TCL and ELTCTL limitations.
2. Meet IEEE 802.3bq 25G / 40GBASE-T standard, the predetermined minimum transmission rate Cat8 eight categories of cable, and to support 25 Gbps to 40 Gbps network cabling.
3. Compliance with ISO / IEC-11801 standard specifies Class I / II Cat8 eight types of cable channel and permanent link.
4. Compliance with ANSI / TIA-1152-A standard specifies eight categories Cat8 cable field tester and measurement accuracy.

In ISO / IEC-11801 standard, the channel level according to the eight kinds of cables Cat8 divided into Class I and Class II these two types:
Class I Cat8 eight types of shielded cable type U / FTP and F / UTP, backward compatible Cat5e, Cat6, Cat6a RJ45 connector interface;
Class II Cat8 eight types of shielded cable type F / FTP or S / FTP, backward compatible TERA or GG45 connector interface.
Eight types of cables (CAT8) divided under three structures:
Structure a: + per pair of shield braided outer shield is +
Structure II: each foil shield shielding + + + outer braided shield
Structure III: each shielding + foil + total outer shield is
Eight types of cables (CAT8) and UTP cable (cat5e), six cable (CAT6) FIG comparison parameters:
Eight categories of network cable (Cat8) seven / Ultra Seven classes cable, as are all shielded twisted pair, application areas: data centers, high speed and bandwidth-intensive areas
From eight types of transmission cables (CAT8) is much smaller than the cable type Ultra Seven, six cable, transmitting only 30 m
Eight types of cables (CAT8) transmission rate and frequency is far more than seven classes cable, six cable.
Eight categories of network cable (Cat8) of little practical use, production eight categories network cable network cable manufacturers less, six cable, UTP cabling line is still the mainstream of science and technology. With the rapid development of network technology will inevitably lead to people's dissatisfaction with the performance requirements of the existing transmission speed, at least 20 years after the Cat8 eight categories of cable systems will gradually become the data center cabling mainstream products.
