2021-03-10

Uyini umehluko phakathi kwentambo yenethiwekhi ye-CAT5e nentambo yenethiwekhi ye-CI-I-AT6?

 

I-CTC Connexions ingumkhiqizi wezintambo zenethiwekhi, izintambo nezintambo ze-coaxial iminyaka eyi-17.

"Isigaba 5e" kubhekiswa esigabeni 5e ipheyiji esontekile engavikelekile.

Ake sibheke umehluko phakathi kwekhebula lenethiwekhi le-Super Category 5 nekhebula lenethiwekhi le-Super Isigaba 6.

Ikhebula le-pair elisontekile elingavikelekile lakhiwa ngamabhangqa amaningi asontekile nomgodla wepulasitiki. Isigaba sesihlanu sibhekisa emazingeni amahlanu ahlukene ekhwalithi achazwe yi-International Electrical Industry Association ngamakhebuli amabili-asontekile.

 

Isigaba 5e ikhebula lamabili elisontekile elingavikelekile liyintambo ebonakala ngemuva kokuthuthuka kwengxenye yokusebenza kwesigaba esivele sivikelekile sesigaba 5. Imingcele eminingi yokusebenza, njenge-crosstalk eseduze, ukuphela kwe-crosstalk ratio, ukulahleka kokubuyisa, njll. Kuthuthukisiwe, kepha umkhawulokudonsa wayo wokuhambisa usengu-100MHz.

 

Isigaba 5 ikhebula lamabili elisontekile lisebenzisa namaphara ama-4 ajikelezayo nocingo olu-1 oluqinile. Umbala walezi zithandani ufana ncamashi nalowo wesigaba 5 esisontekile, esingumbala osawolintshi omhlophe, owolintshi, ohlaza okotshani, ohlaza okotshani, omhlophe okwesibhakabhaka, ohlaza okwesibhakabhaka nomhlophe. Mnyama onsundu. Ububanzi bezintambo zethusi ezingenalutho ngu-0.51mm (i-gauge yensimbi ingu-24AWG), ububanzi bocingo oluhlanganisiwe ngu-0.92mm, kanti ububanzi bekhebula le-UTP ngu-5mm. Yize i-Category 5e pair engasontiwe esontekile ingaphinde inikeze nge-bandwidth yokudlulisela ye-1000Mb / s, imvamisa idinga ukwesekwa kwemishini ekhethekile ebizayo. Ngakho-ke, imvamisa isetshenziswa kuphela ku-100Mb / s fast Ethernet ukuxhuma iswishi yedeskithophu kwikhompyutha. Uma ungeke uthuthukise inethiwekhi yakho ibe yiGigabit Ethernet ngokuzayo, ungahle usebenzise isigaba esine-5e esingavikelekile esisontekile kukhebuli evundlile.

 

"CI-I-AT6"kubhekiselwa esigabeni sesithupha esisontekile esingaphendulwanga

 

Imingcele yezinhlobo eziyisithupha zamabhangqa asontekile angasetshenziswanga ithuthukiswe kakhulu, futhi umkhawulokudonsa nawo unwetshelwe ku-250MHz noma ngaphezulu. Izintambo zombili zesigaba 6 ezisontekile zihlukile kusigaba 5 noma Isigaba 5 ngazimbili ezisontekile ngokubukeka nokwakheka. Uhlaka lwesiphambano olungavimbelwe alukhuphuki nje kuphela, amapheya amane wamabhangqa asontekile abekwa kolwesine lohlaka lwesiphambano. Ngaphakathi kwe-groove, kanye nobubanzi bekhebula nalo lukhulu.

 

Uhlaka lwesiphambano enkabeni yekhebula luzungeza noshintsho lobude, futhi amabhangqa amane asontekile aboshelwe emgodini wohlaka ukuze kugcinwe isimo esilinganayo samabhangqa amane asontekile ukuthuthukisa izici zebhalansi nokuncishiswa kwekhebula . Ngaphezu kwalokho, qiniseka ukuthi ukwakheka kwekhebula akulimazi ngesikhathi senqubo yokufaka. Ububanzi bezintambo zethusi ezingenalutho zoMkhakha wesi-6 ongashintshiwe ongasetshenziswanga ngu-0.57mm (igeji yocingo ingu-23AWG), ububanzi bocingo oluhlanganisiwe ngu-1.02mm, kanti ububanzi bekhebula le-UTP ngu-6.53mm.

 

Yikuphi okungcono, ikhebula lenethiwekhi le-CAT5e nomaCI-I-AT6 network cable?

 

Ngokuya ngokusebenza okuhlukile kukagesi, ama-pair asontekile angahlukaniswa abe yizinhlobo ezintathu, izinhlobo ezinhlanu, izinhlobo ezinhlanu ezinhle, izinhlobo eziyisithupha nezinhlobo eziyisikhombisa zamabhangqa asontekile. Amanani ezinhlobo ezahlukahlukene zamakhebuli asontekile ahluke kakhulu noma ahlukile, futhi ububanzi besicelo buhluke kakhulu.

 

Ngaphandle kokuthi uhlelo lwezwi lwendabuko lusasebenzisa izigaba ezisontekile zesigaba 3, ukufakwa kwamanethiwekhi njengamanje kusetshenziswa izigaba ezisontekile ezihlukanisiwe ezingaphansi kwesigaba 5 noma isigaba 6. Yize ikhebula lamawele asontekile angaphansi kwesigaba 5 lisengakwazi ukuxhasa i-1000Base-T, iye yaphela kancane kancane emakethe yamatabernakele ngoba icishe ifane nentambo yamapheya asontekile angaphansi kwesigaba 5 ngokwentengo.

 

   Yize intengo ye-Isigaba 6 ipheya eligoqiwe elingavikelekile liphezulu kakhulu, kancane kancane iba yintandokazi entsha yezintambo ezihlanganisiwe ngenxa yokuhambisana kwayo okuhle kakhulu nohlelo lweClass 5 cabling kanye nekhono lokuxhasa kahle i-1000Base-T. I-CAT7 evikelwe ngababili abasontekile uhlelo olusha sha lwezintambo. Yize inokusebenza okuhle kakhulu, kuyabiza. Ukwakhiwa kuyinkimbinkimbi futhi kunemikhiqizo embalwa ongakhetha kuyo, ngakho-ke akuvamile ukuthi isetshenziswe kumaphrojekthi wezintambo.

 

CI-I-AT6okungavikelekile okungavikelekile Ikhebula can support Gigabit Ethernet very well and achieve a transmission distance of 100m. Therefore, the Isigaba 6 wiring system is widely used in the wiring of the sub-server computer room and the horizontal wiring that retains the ability to upgrade to Gigabit Ethernet. According to the international cabling standard ISO 11801, the life expectancy of a cabling system is at least 10 years. As a long-term basic investment, integrated cabling should fully consider the potential needs of the network and the development of the cabling system. Therefore, it is recommended to choose six types of products to build the cabling system under the condition of capital permitting.

 

Uma ubheka izidingo zesikhathi esizayo zenethiwekhi, kufanele kufakwe imikhiqizo yezintambo esezingeni eliphakeme kakhulu, ngoba kaningi kunzima ukuyibuyekeza nokuyishintsha ngemuva kokufakwa kwezintambo. Ngokuyisisekelo, uhlelo lwezintambo kufanele lusetshenziswe njengejwayelekile okungenani iminyaka eyi-10 futhi lungaxhasa izizukulwane ezi-4 kuye kwezi-5 zamanethiwekhi Ukusebenza kwemishini kuyabuyekezwa, uma imishini yenethiwekhi yesikhathi esizayo idinga ikhebula elingcono ukukhuphula isivinini sedatha.

 

So, it is inevitable to use Isigaba 6 cables to replace Category 5e cables, but these cables are very expensive to rebuild, so even if the price of Isigaba 6 products is slightly more expensive than Category 5 products, in order to reduce future network upgrade problems, Six types of products are still worth considering.
