Ukwethulwa kwekhebula lenethiwekhi le-CAT8

 

Uma ukumboni yokuxhumana yenethiwekhi, ngikholwa ukuthi kufanele wazi izintambo ezithile ze-Ethernet, njenge Isigaba 5eikhebula lenethiwekhi,Isigaba 6 ikhebula lenethiwekhiand Category 7 network cable. But do you know what Cat8 eight-category ikhebula lenethiwekhiis? How is it different from Category 5 network cable, Isigaba 6/Super 6 ikhebula lenethiwekhiand Category 7/Super 7 network cable? Let's take you to know the new generation of network jumpers-Cat8 eight types of network cables.

 

Izinhlobo ze-Cat8 eziyisishiyagalombili zekhebula lenethiwekhi yisizukulwane se-jumper yenethiwekhi evikelwe kabili (SFTP), inezimbili zocingo ezimbili, ingasekela umkhawulokudonsa ka-2000MHz, futhi izinga lokudlulisa lifinyelela ku-40Gb / s, kepha ibanga lokudlulisa li-30m kuphela, ngakho-ke kuvamise ukusetshenziselwa okufushane Ukuxhuma kwamaseva, amaswishi, ama-patch panels neminye imishini esikhungweni sedatha.

 

Amazinga afanele e-Cat8 izinhlobo eziyisishiyagalombili zezintambo zenethiwekhi akhishwa ngokusemthethweni yiKomidi le-TR-43 leTelecommunications Industry Association (TIA) ngo-2016. Imininingwane imi kanje:

 

1. Ihambisana nezinga elijwayelekile le-IEEE 802.3bq 25G / 40GBASE-T, icacisa isilinganiso esincanyana sokudluliswa kwezinhlobo eziyisishiyagalombili zeCat8 zezintambo zenethiwekhi, futhi ingakwazi ukusekela iklabishi yenethiwekhi ye-25 Gbps ne-40 Gbps.

 

2. Ihambisana nezinga le-ANSI / TIA-568-C.2-1, ichaza isiteshi kanye nokuxhumanisa unomphela kwekhebula lezinethiwekhi eziyisishiyagalombili zeCat8, futhi kufaka nemikhawulo yokungalingani kokumelana, i-TCL ne-ELTCTL.

 

3. Ihambisana ne-ANSI / TIA-1152-A ejwayelekile, ebeka isilinganiso nezidingo zokunemba kweCat8 isigaba sesishiyagalombili senkundla yokuhlola ikhebula.

 

4. Ihambisana nezinga le-ISO / IEC-11801, elisho isiteshi nokuxhumanisa unomphela kwekhebula lenethiwekhi le-I / II Category 8 Cat8.

 

izinhlobo ezi-8 zezintambo zenethiwekhi

 

Kuzinga elijwayelekile le-ISO / IEC-11801, izintambo zenethiwekhi ezinamazinga ayisishiyagalombili zehlukaniswe zaba Isigaba I no-II ngokwezinga lesiteshi. Phakathi kwazo, izinhlobo zokuvikela izintambo zenethiwekhi ezihlukaniswe ngezigaba eziyisishiyagalombili ze-Category I Cat8 yi-U / FTP ne-F / UTP, ezibuyela emuva ezihambisana neCat5e neCat6. , Isixhumi esibonakalayo se-Cat6a RJ45; Izinhlobo zesigaba II Cat8 izinhlobo eziyisishiyagalombili zohlobo lwentambo yokuvikela ikhebula yi-F / FTP noma i-S / FTP, emuva iyahambisana ne-TERA noma i-GG45 interface interface.

 

The difference between Cat8 Category 8 ikhebula lenethiwekhiand Isigaba 5e network cable, Isigaba 6 network cable, Isigaba 6 ikhebula lenethiwekhiand Isigaba 7 / Isigaba 7ikhebula lenethiwekhi

 

Cat8 Category 8 network cables are shielded twisted-pair cables, like Category 7/Super 7 network cables. They can be used in data centers, high-speed and bandwidth-intensive places, although the transmission distance of Cat8 Category 8 cables is not as good as Category 7/Super 7 network cables. It is far, but its speed and frequency are far beyond the CAT7/Super CAT7 network cable. There is a big difference between Cat8 Category 8 ikhebula lenethiwekhiand Isigaba 5e network cable, Isigaba 6/Isigaba 6 network cable, which is mainly reflected in the speed, frequency, transmission distance and application.
