Ikhebula le-Cat5/5e, i-Cat6/6a, i-Cat7 kanye ne-Cat8: Umhlahlandlela Ophelele

2025-02-26

Ngidinga umhlahlandlela ophelele wezintambo ze-Cat5/5e, Cat6/6a, Cat7, kanye ne-Cat8. Engikwaziyo ngalezi zigaba. Inombolo ngayinye ye-Cat imelela imininingwane ehlukene yezintambo ze-Ethernet, Ziyahlukahluka ngokuya ngesivinini, i-bandwidth, ukuvikela, kanye mhlawumbe nebanga ezingalidlulisela ngempumelelo idatha.

ikati5 ikati6 ikati7 ikati8.jpg

Okokuqala, kufanele ngichaze isigaba ngasinye ngasinye. Ake sibone. I-Cat5 indala, mhlawumbe ifinyelela ku-100 Mbps? Kodwa i-Cat5e ithuthukisiwe, isekela kufika ku-1 Gbps. Khona-ke i-Cat6 ingenza i-1 Gbps ebangeni elide, mhlawumbe i-10 Gbps kodwa imfushane. I-Cat6a ithuthukisiwe, ngakho ukusebenza okungcono, mhlawumbe i-10 Gbps ebangeni elingaphezu kwamamitha ayi-100. I-Cat7 ivikelwe, ijubane eliphezulu, kodwa isebenzisa izixhumi ezahlukene? Futhi i-Cat8 yenzelwe izikhungo zedatha, ijubane eliphezulu kakhulu kodwa ibanga elifushane.

Linda, ngidinga ukuthola imininingwane efanele. Ake ngihlole inkumbulo yami. I-Cat5e ingu-1 Gbps kuze kufike kumamitha ayi-100. I-Cat6 ingenza i-10 Gbps kuze kufike kumamitha angu-55. I-Cat6a inweba lokho kuze kufike kumamitha ayi-100 nge-10 Gbps. I-Cat7 ikalwe nge-10 Gbps kuze kufike kumamitha ayi-100 futhi mhlawumbe imvamisa ephezulu. I-Cat8 yakhelwe i-25 noma i-40 Gbps kuze kufike kumamitha angu-30. Futhi, ukuvikela kuyisici; izigaba eziphakeme zinokuvikela okwengeziwe ukunciphisa ukuphazamiseka.

Kufanele futhi ngikhulume ngomehluko wokwakhiwa, njenge-UTP (i-unshielded twisted pair) vs. STP (evikelwe). I-Cat5e ivame ukuba yi-UTP, kanti i-Cat6a nangaphezulu ingasebenzisa isivikelo. I-Cat7 isebenzisa izixhumi ze-GG45 noma i-TERA, kodwa isahambisana ne-RJ45. Linda, ingabe lokho kulungile? Mhlawumbe i-Cat7 ivame ukusebenzisa i-RJ45 kodwa ngokuvikela okwengeziwe. I-Cat8 ngokuqinisekile isebenzisa i-RJ45.

Izinhlelo zokusebenza nazo zibalulekile. Isibonelo, i-Cat5e yamanethiwekhi asekhaya, i-Cat6 yamahhovisi, i-Cat7 yezimboni, kanye ne-Cat8 yezikhungo zedatha. Izindleko zingenye isici; izigaba eziphakeme zibiza kakhulu. Ukuvikela esikhathini esizayo kungaba yinto okufanele icatshangelwe. Futhi, ubude bekhebula nokuthi ngabe liyi-core eqinile noma ebambekile. O, kulungile, i-core eqinile ingeyokufakwa okuhleliwe, ebambekile yezintambo ze-patch.

Ngidinga ukuhlela umhlahlandlela ngezigaba zohlobo ngalunye lwekhebula, imininingwane ebalulekile (isivinini, umkhawulokudonsa, ibanga), ukuvikela, izinhlelo zokusebenza, kanye neshadi lokuqhathanisa. Bese kuhlanganisa izinto okufanele uzicabangele njengokuthenga izidingo zohlelo lokusebenza, ukuvikela ikusasa, isabelomali, indawo ezungezile (ukuphazamiseka komsindo), kanye nohlobo lokufaka (okuqinile vs. okusele).

Linda, kufanele ngihlole kabili isivinini esiphezulu kanye namabanga. Ake ngiqinisekise: I-Cat5e ingu-1 Gbps ku-100 MHz ngaphezu kwe-100m. I-Cat6 ingu-1 Gbps kuze kufike ku-100m, i-10 Gbps kuze kufike ku-55m. I-Cat6a ingu-10 Gbps ku-500 MHz ngaphezu kwe-100m. I-Cat7 ingu-10 Gbps ku-600 MHz ngaphezu kwe-100m, kanye ne-Cat7a kuze kufike ku-1000 MHz. I-Cat8 ingu-25/40 Gbps ku-2000 MHz kuze kufike ku-30m. Futhi, i-Cat7 kanye ne-8 zinezidingo zokuvikela eziqinile.

Ukufaka i-bandwidth (MHz) kubalulekile ngoba lokho kuthinta amandla okudlulisa idatha. Izixhumi: I-Cat8 isebenzisa i-RJ45, kodwa ama-Cats angaphambilini angase abe nezinhlobo ezahlukene zokuvikela. Futhi, ukuhambisana nengqalasizinda ekhona. Isibonelo, ukusebenzisa i-Cat6a nama-Cat5e jacks kungase kungasebenzisi amandla aphelele.

Kufanele ngisho ukuthi izigaba eziphakeme zisekela ama-bandwidth aphezulu ngakho-ke zingcono kumanethiwekhi anesivinini esikhulu, kodwa zingase zibe ngaphezulu kokusetshenziswa okuyisisekelo. Futhi, umehluko womzimba njengobukhulu kanye ne-radius egobile. I-Cat6a ijiyile futhi ayiguquguquki kakhulu kune-Cat5e.

Ekucabangeni kokuthenga, izici ezifana nezidingo zamanje nezesikhathi esizayo, imvelo (yezimboni enokuphazamiseka vs ikhaya), nokuthi ngabe ziyayidinga yini i-PoE (Amandla phezu kwe-Ethernet), yiziphi izigaba eziphakeme ezingase zisekele kangcono.

Ngidinga ukuqinisekisa ukuthi umhlahlandlela ulula ukuwuqonda, ngigwema amagama amaningi obuchwepheshe, kodwa usanikeza ulwazi. Mhlawumbe ithebula elifushane lesifinyezo ekuqaleni, bese kuba nezingxenye ezinemininingwane. Futhi, izimo ezivamile zokusetshenziswa ukusiza abafundi banqume ukuthi yikuphi abakudingayo.

Linda, kufanele ngihlole ukuthi i-Cat7 iyaqashelwa yini ngezindinganiso ze-TIA/EIA noma ukuthi iyindinganiso ye-ISO. Ngoba ngezinye izikhathi i-Cat7 ayisetshenziswa kabanzi ezindaweni ezithile. I-Cat6a ne-Cat8 zisezingeni eliphezulu. Lokho kungaba iphuzu okufanele licatshangelwe ngaphansi kokucatshangelwa, njengokuhambisana nezindinganiso ezikhona.

Futhi, umehluko wezindleko. I-Cat5e ishibhile kakhulu, bese kuba yi-Cat6, Cat6a, Cat7, Cat8 ebiza kakhulu. Ngakho-ke isabelomali siyisici. Kwabasebenzisi abaningi basekhaya, i-Cat5e noma i-Cat6 yanele. Emakhaya ahlakaniphile anamadivayisi amaningi, mhlawumbe i-Cat6. Ezikhungweni zedatha, i-Cat8.

Ukubeka phansi kungaba yinkinga ngezintambo ezivikelwe; uma zingasekelwe kahle, ukuvikela kungabangela izinkinga. Ngakho ukufakwa kwezintambo ezivikelwe kudinga amasu afanele.

Ngamafuphi, umhlahlandlela kufanele uhlanganise imininingwane yohlobo ngalunye lwekhebula, uwaqhathanise, futhi uqondise umfundi ngokusekelwe ezidingweni zakhe ezithile: izidingo zesivinini, ibanga, indawo ezungezile, isabelomali, kanye nezinhlelo zesikhathi esizayo.

Ikhebula le-Cat5/5e, i-Cat6/6a, i-Cat7, kanye ne-Cat8: Umhlahlandlela Ophelele

Ukukhetha ikhebula le-Ethernet elifanele kuncike kwisivinini senethiwekhi yakho, ibanga, kanye nezidingo zemvelo. Nasi umhlahlandlela omfushane ozokusiza ukuthi unqume:

Ithebula Lokuqhathanisa Okusheshayo

- Amakhebula okunamathisela:I-Stranded-core(okuguquguqukayo).

Amathiphu Okugcina

Ukuvikela: Kuyadingeka ezindaweni ezinomsindo kodwa kudinga isisekelo esifanele.
Amazinga: I-Cat6a kanye ne-Cat8 ziyaqashelwa yi-TIA/EIA; i-Cat7 ilandela i-ISO.
Usekelo lwe-PoEZonke izigaba zisekela i-PoE, kodwa amazinga aphezulu aphatha ukushisa kangcono.

Khetha ngokusekelwe ezidingweni zakho zamanje ngenkathi ucabangela ukuthuthukiswa kwesikhathi esizayo. Izindlu eziningi ziyachuma nge-Cat6, kuyilapho amabhizinisi kufanele athambekele ku-Cat6a noma ku-Cat8.

Xhumana Nathi, Thola Imikhiqizo Esezingeni Eliphezulu kanye Nensizakalo Yokunaka.

Ngokusetshenziswa okukhulu kwe-FTTH Fiber ekhaya, izikhungo zedatha ze-AI computing, i-5G fronthaul, izintambo ezibanzi zangaphakathi, ukuxhumana okuncane kwe-FPV drone kanye nokwakhiwa kokuvuselelwa kwamanje okubuthakathaka emhlabeni wonke, intambo yendabuko ye-G.652D single-mode ihlushwa ukulahlekelwa okukhulu kokugoba kanye nesikhala esilinganiselwe socingo, okuvimbela kakhulu ukwakheka kwamanethiwekhi okuxhumana we-optical asheshayo. Yakhiwe yi-ITU-T, intambo ye-single-mode engazweli uchungechunge lwe-G.657 series bend-insensitive ithuthukiswe ngokukhethekile kumakhona amancane okujika, izintambo ezixinene kanye nezimo zepayipi elincane. Amabanga amathathu omkhiqizo ojwayelekile, intambo ejwayelekile engazweli ukugoba ye-G.657.A1, intambo ethuthukisiwe engazweli ukugoba ye-G.657.A2 kanye nentambo engazweli ukugoba ye-G.657.B3 ultra-bend, isebenzisa amaphrofayili enkomba yokubuyisa asekelwe emseleni ahlukene, futhi aveza umehluko olinganisiwe ku-radius encane yokugoba, ububanzi bensimu yemodi kanye nokusebenza kokunciphisa. Zihlanganisa izidingo zesimo esigcwele kusukela kuzintambo zasekhaya ezingabizi kakhulu kuya kuzintambo ezikhethekile eziqinile kakhulu.
