izintambo ze-ethernet Abalulekile ekuxhumekeni ku-inthanethi namanethiwekhi endawo, okuvumelayo ukudluliswa okusheshayo futhi ozinzile ngaphandle kwe-WiFi. Nokho, ukukhetha kwakho kungase kudide ngenxa yezinhlobonhlobo zezinhlobo nezigaba ezitholakalayo. Ngenhlanhla, ukuqonda umehluko nokusetshenziswa okuthile kwekhebula ngalinye kungakusiza wenze izinqumo. izinqumo ezingcono ukuze uthuthukise ukufakwa kwenethiwekhi yakho.
Kulesi sihloko sizohlola izinhlobo ezahlukene Izintambo ze-Ethernet, kusukela kwezivamile kuya kwezithuthuke kakhulu. Sizophinde sibuyekeze izigaba, ukuthi zimele ini kanye ukuthi zithinta kanjani isivinini, ukuzinza nokuvikelwa kokuxhuma. Ukwengeza, sizokhuluma ngezinketho zokuvikela kanye amabanga aphezulu isekelwa uhlobo ngalunye lwekhebula, ngakho ungakhetha ofaneleka kakhulu ngokwezidingo zakho.
Iyini ikhebula le-Ethernet?
Labo abasebenzisa i-Wi-Fi ukuze baxhume ku-inthanethi abazi ukuthi kulula yini ukusebenzisa intambo ye-Ethernet. Futhi, nakuba kunezinhlelo zokusebenza ezikusiza ukuthi uthole uxhumano olungcono kakhulu lwe-Wi-Fi, uxhumano lwekhebula luzohlala lusezingeni elingcono.
Un ikhebula le-ethernet Kuyikhebula eliphathekayo elixhumanisa amadivaysi kunethiwekhi yendawo noma i-inthanethi. Ngokuvamile isetshenziselwa ukuxhuma amakhompyutha, amarutha, amaswishi noma amadivaysi afana nama-consoles nama-Smart TV. Lolu hlobo lokuxhumana lunalo izinzuzo ezibalulekile uma kuqhathaniswa ne-WiFi, njengejubane eliphezulu, ukubambezeleka okuphansi kanye nokuphazamiseka okuncane.
Izinga elisetshenziswa kakhulu izintambo ezine Isixhumi se-RJ45, osekusele njengoba intandokazi kumanethiwekhi endawo. Nakuba izintambo zingase zibonakale zifana ngokoqobo, umehluko wazo wangaphakathi njengokuxhunywa kwezintambo, amazinga okuvikela kanye nezigaba ezinqumayo. ukusebenza.
Izigaba zekhebula le-Ethernet
Izigaba zezintambo ze-Ethernet, ezikhonjwe ngokuthi CAT kulandelwa inombolo, achaza amandla aphezulu ngokwejubane, imvamisa namabanga asekelwe. Okulandelayo, sihlaziya izigaba ezifanele kakhulu:
- I-CAT 5: Okwamanje yehlisiwe, isekela kufika I-100 Mbps nemvamisa ye 100 MHz.
- I-CAT 5e: Ithuthukiswe nge-CAT 5, ivumela isivinini esingafika ku- 1.000 Mbps (1 Gbps) nemvamisa efanayo ye 100 MHz.
- I-CAT 6: Khulisa imvamisa ukuze 250 MHz futhi isekela isivinini esifika ku I-10 Gbps emabangeni angaphansi Amamitha angu-55.
- I-CAT 6A: Inikeza ukuzinza okukhulu kanye nemvamisa ye 500 MHz ngesivinini se I-10 Gbps ebangeni kuze kube Amamitha angu-100.
- I-CAT 7: Isekela isivinini se I-10 Gbps nemvamisa ye 600 MHz, ngokuvikela okukhulu ukunciphisa ukuphazamiseka.
- I-CAT 7A: Ithuthukisa imvamisa ukuze 1.000 MHz, ukugcina isivinini se I-10 Gbps.
- I-CAT 8: Inketho ethuthuke kakhulu, efinyelela ku I-40 Gbps kanye nemvamisa ye 2.000 MHz, ilungele izindawo ezifunayo njengezikhungo zedatha.
Izinhlobo zokuvikela kuzintambo ze-Ethernet
El ukuvikela Kuwukunamathela okuvikela izintambo zangaphakathi ekuphazamisekeni kozibuthe. Kunezinhlobo ezine eziyinhloko:
- I-UTP (Ukubhangqa Okusontekile Okungavikelwe): Ngaphandle kokuvikela, kunjalo ezomnotho futhi ilungele ukusetshenziswa ekhaya noma amabanga amafushane.
- I-FTP (I-Foiled Twisted Pair): Ine-global aluminium coating evikela wonke amapheya ezintambo.
- I-STP (Ukubhangqa Okusontekile Okuvikelekile): Ipheya ngalinye lamakhebula livikelwe ngensimbi ngayinye, elilungele ukufaka okuyinkimbinkimbi.
- I-SFTP (Ukubhangqa Okusontekile Kwesihlangu Esifolisiwe): Ihlanganisa ukuvikela kwe-FTP kanye ne-STP, kube inketho eqine kakhulu indlela ende noma izindawo ezinokuphazamiseka okuningi.
Isivinini esikhulu namabanga
Isigaba ngasinye se ikhebula le-ethernet Iklanyelwe ukumelana nemikhawulo ethile ye velocity y ibanga. Isibonelo:
I-CAT 5e ne-CAT 6: kuze Amamitha angu-100 ngejubane le I-1 Gbps. Endabeni ye-CAT 6, ingafinyelela I-10 Gbps emabangeni amafushane.
I-CAT 6A nangaphezulu: Ihambisana nesivinini se I-10 Gbps a Amamitha angu-100. I-CAT 8 ingafinyelela I-40 Gbps, kodwa kuze kube Amamitha angu-30.
Kubalulekile ukukhumbula lokho ukuphazamiseka noma ikhwalithi yekhebula ingase ibe nomthelela ekusebenzeni kwangempela.
Indlela yokuhlukanisa nokukhetha ikhebula elifanele
Ukuhlonza isigaba sika-a ikhebula le-ethernet, kumelwe ufunde umbhalo osesembozweni sawo sepulasitiki. Kufanele futhi ucabangele ukusetshenziswa ozokunikeza:
- Ukusetshenziswa okujwayelekile ekhaya: I-CAT 5e noma i-CAT 6 yanele.
- Ukufakwa okuzayo noma okudingekayo: Khetha i-CAT 6A noma i-CAT 7.
- Izikhungo zedatha: Khetha i-CAT 8 ukuze uqinisekise Isivinini esikhulu kanye nokuzinza.
Amaqhinga okwenza awakho amakhebuli e-Ethernet
Uma udinga a ikhebula langokwezifiso, ungathenga ikhoyili yekhebula ye-Ethernet nezixhumi ze-RJ45 ukuze uziqophe ngokwakho. Uzodinga amathuluzi afana nethuluzi lokukhiya kanye nesikelo. Ngemva kokukhumula ikhebula nokuhlunga imibala ngokohlobo lokuxhuma (A noma B), kuzodingeka wenze kanjalo kuphela beka isixhumi necrimp (noma ukuphambana kwezintambo).
Inani lemali nezinto zokwakha
Izinga lezinto, njengephesenti le ithusi ezintanjeni, kuthinta ngqo ukusebenza kwekhebula. Izintambo zokuhlanzeka eziphakeme zine ukulahlekelwa kwesignali ephansi kanye nokuqina okukhulu. Gwema izintambo ezishibhile eziqukethe i-aluminium egqoke ithusi, njengoba bengathembeki kangako.
Khetha ikhebula le-Ethernet elifanele Akugcini nje ngokuthuthukisa ukusebenza kwenethiwekhi yakho, futhi ikulungiselela izidingo zobuchwepheshe zesikhathi esizayo. Ngokwazi umehluko phakathi kwezigaba nokuvikela, ungenza izinqumo ezinolwazi futhi ujabulele ukuxhumana okungcono. iyashesha, izinzile futhi isebenza kahle.
