Ungayikhetha kanjani i-CAT6 noma i-CAT5E ye-PoE switch?

Ungakhetha kanjaniCI-AT6nomaCAT5E ye-PoE Shintsha?

Ukushintshwa kwe-POE akunakwehlukaniswa nekhebula lenethiwekhi ngesikhathi sokunikezwa kwamandla, ngakho-ke kufanele ikhethwe kanjani ikhebula lenethiwekhi?

 

Ikhebula lenethiwekhi kumele lixhunywe kwikhebula lenethiwekhi ngokuya ngebanga elingu-568A noma elingu-568B, izintambo eziyi-8 kufanele zixhunywe, futhi ubude bube phakathi kwamamitha ayi-100. Uma ikhwalithi yekhebula lenethiwekhi iba ngcono, kukhuphuka ukuzinza kokudluliswa, okungenani aCAT5Eikhebuli, uma isabelomali sanele, ungakhetha ifayela le-CAT6 ikhebuli enebanga elide lokudlulisela nomphumela ongcono.

 

 

 

 

 

CAT5E

 

Ikhebuli leCat5e linezinzuzo zokwehliswa okuphansi, i-crosstalk encane, isilinganiso esiphakeme se-crosstalk isilinganiso kanye ne-signal-to-noise ratio, nephutha elincane lokubambezeleka. Izintambo zesigaba 5e zisetshenziselwa ikakhulukazi iGigabit Ethernet.

 

 

 

 

CI-AT6

Imvamisa yokudlulisa yalolu hlobo lwentambo yi-1MHz ~ 250MHz, futhi isilinganiso esiphelele sokuncishiswa kokuncishiswa kohlelo lwesigaba 6 somugqa ku-2000mhz sinomkhawulo omkhulu, ohlinzeka kabili umkhawulokudonsa weSuper Category 5. Ukusebenza kokudluliswa kweSigaba 6 kuklabishi kuphakeme kakhulu kunokwesigaba se-5 cabling, futhi ilungele kakhulu izinhlelo zokusebenza ezinenani lokudlulisela eliphakeme kune-1Gbps.

 

 

 

 

Umehluko obalulekile phakathi kolayini abakhulu abayisihlanu nabayisithupha

 

Imigqa yesigaba 6 ithuthukise ukusebenza kwe-crosstalk nokulahlekelwa okubuyayo. Ngokwesizukulwane esisha sezinhlelo zokusebenza zenethiwekhi ezinejubane eliphakeme, ukusebenza okuhle kakhulu kokulahleka kubaluleke kakhulu. Ngasikhathi sinye, imodeli yesixhumanisi eyisisekelo ikhanseliwe ezinhlotsheni eziyisithupha zamazinga, futhi ukwakheka kwezinkanyezi kwamukelwa ngamazinga angenamkhawulo. Ubude besixhumanisi baphakade sebanga lezintambo akumele budlule amamitha ayi-90, futhi ubude besiteshi akumele budlule amamitha ayi-100.

 

 

 

Kufanele ukushintshwa kwe-POE kukhethe izintambo zenethiwekhi? Ukushintshwa kwe-POE kufanele kukhethe izintambo zenethiwekhi.

 

Ukufeza umphumela omuhle wokunikezwa kwamandla we-PoE, kunconywa ukuthi kusetshenziswe izintambo zenethiwekhi zesigaba 5, izintambo zesigaba 5 senethiwekhi enkulu, nezintambo zenethiwekhi zesigaba 6. Okuqukethwe kwangaphakathi kwekhebula lenethiwekhi nakho kubaluleke kakhulu. Ungasebenzisi noma iyiphi i-aluminium wire, i-copper-clad aluminium wire, i-copper-clad iron wire, i-iron core wire, njll. Kungcono ukusebenzisa i-pure wire wire.

 

 

 

There are basically logos on the network cables. The logo for Category 5 cables is "CAT5", the logo for Category Super 5 cables is "CAT5E", and the logo for Category 6 cables is "CI-AT6". The later the better. In addition, the characters printed on the plastic sheath of the real Category 5 line are very clear, smooth, and basically not jagged. The printing quality of the fake handwriting is poor, some fonts are unclear, and some are severely jagged.
