Uyini umehluko phakathi kwe-Ca5e, i-Cat6, ne-Cat7?

Isigaba Sesihlanu (CAT5): Imvamisa yokudlulisa ingu-100MHz, esetshenziselwa ukudlulisa kwezwi nokudluliswa kwedatha ngezinga eliphezulu lokudlulisela elingu-100Mbps, elisetshenziswa kakhulu kumanethiwekhi angu-100BASE-T kanye ne-10BASE-T. Lena ikhebuli ye-Ethernet esetshenziswa kakhulu. Lolu hlobo lwekhebula lukhulisa ukuminyana okumazombezombe futhi lumboza i-insulating material yekhwalithi ephezulu. Manje ikhebula leSigaba 5 empeleni alisetshenziswa kakhulu.

Isigaba 5e (CAT5e): Imvamisa yokudlulisa ngu-100MHz, ikakhulukazi esetshenziselwa i-Gigabit Ethernet (1000Mbps). Inokumiswa okuncane, i-crosstalk encane, i-attenuation ephakeme kanye ne-crosstalk ratio (ACR) kanye ne-signal-to-noise ratio (I-Structural Return Loss), kanye nephutha lokulibaziseka elincane, futhi ukusebenza kuba ngcono kakhulu. Kumaphrojekthi wangempela, nakuba izintambo zeSigaba 5 zingaphinda zidlulise i-gigabit, kunconywa kuphela ukudluliselwa kwegigabit ebangeni elifushane. Ukudluliswa kwegigabit amabanga amade kungase kungazinzi. Lokhu futhi kuyiphutha elivamile kuphrojekthi, futhi kulula ukuziba. Inkinga.

Isigaba Sesithupha (CAT6): Imvamisa yokudlulisa ngu-250MHz, efaneleke kakhulu izinhlelo zokusebenza ezinamazinga okudlulisela aphezulu kuno-1Gbps, ikakhulukazi i-Gigabit Ethernet (1000Mbps). Isigaba sesi-6 sokupheya esisontekile sihlukile kokuthi Isigaba 5 noma Isigaba 5 sokupheya okusontekile kakhulu ngokubukeka nesakhiwo, akufakiwe nje kuphela uhlaka oluyisiphambano oluvikelayo olufakwayo, kodwa amapheya amane okupheya okusontekile abekwe ezinhlangothini ezine zozimele ophambanayo ngokulandelana. ngaphakathi kwe-groove, futhi ububanzi bekhebula nalo likhulu.

I-Super six noma i-6A (CAT6A): imvamisa yokudlulisela ingu-200 ~ 250 MHz, isivinini sokudlulisa esiphezulu singafinyelela ku-1000 Mbps, ikakhulukazi esetshenziswa kumanethiwekhi e-gigabit. Ikhebula lesigaba 6e inguqulo ethuthukisiwe yekhebula yeSigaba 6. Futhi iyikhebula elisontekile elingavikelekile elicaciswe kumazinga e-ANSI/EIA/TIA-568B.2 kanye ne-ISO Esigaba 6/Class E. Uma kuqhathaniswa nezinye izici, kukhona intuthuko enkulu.

Isigaba Sesikhombisa (CAT7): Imvamisa yokudlulisela ingafinyelela okungenani ku-500 MHz futhi izinga lokudlulisela lingafinyelela ku-10 Gbps. Ngokuyinhloko ukuzivumelanisa nokusetshenziswa nokuthuthukiswa kobuchwepheshe be-10 Gigabit Ethernet. Lo mugqa uyipheya yakamuva evikelekile esontekile esigabeni se-ISO 7.

Umehluko omkhulu phakathi kwezinhlobo ezahlukene zocingo

Umehluko 1: Umehluko ekulahlekeni, umehluko obalulekile phakathi kwekhebula leSigaba 6 nekhebula lenethiwekhi Yesigaba 5e ukusebenza okuthuthukisiwe ngokuya nge-crosstalk nokulahlekelwa kokubuyisela. Kunconywa ukusebenzisa izintambo zenethiwekhi zeSigaba 6 ngokuqondile ukuhlobisa ikhaya.

Umehluko 2. Ubukhulu be-wire core buhlukile. Intambo yocingo yekhebula yenethiwekhi yohlobo lwe-super five iphakathi kuka-0.45mm no-0.51mm, kanti ingqikithi yocingo yekhebula yenethiwekhi yohlobo oluyisithupha iphakathi kuka-0.56mm no-0.58mm. Intambo yenethiwekhi inkulu kakhulu;

Umehluko wesi-3: Isakhiwo sekhebula sihlukile. Indawo engaphandle yekhebula yenethiwekhi yohlobo oluyisihlanu ephezulu inophawu lwe-“CAT.5e”, futhi ikhebula yenethiwekhi yezinhlobo eziyisithupha “inefreyimu ephambene” esobala kakhulu, futhi isikhumba sinelogo ethi “CAT.6″.
