Ukuxhuma izintambo ehhovisi lakho kuyingxenye ebalulekile yenethiwekhi yakho yekhompyutha. Yilokho okuxhumanisa wonke amadivayisi akho, futhi kudinga ukuhlelwa ukuze kwenziwe kanjalo kahle. Kunezinhlobo eziningi ezahlukene zokuxhuma izintambo zenethiwekhi ezihlelekile ongakhetha kuzo, ngayinye inezinzuzo zayo kanye nokungalungi kwayo. Ukuze sikusize unqume ukuthi yiluphi uhlobo olufanele ibhizinisi lakho, nakhu konke okudingeka ukwazi ngezinye zezinketho zokuxhuma izintambo zenethiwekhi ezivame kakhulu ezitholakala namuhla.
Ikhebula lenethiwekhi elakhiwe
Amandla, idatha kanye nezwi
Kunezinhlobo ezintathu zezintambo: amandla, idatha kanye nezwi. Izintambo zikagesi zisetshenziselwa ukudlulisa ugesi; idatha, ulwazi ngenethiwekhi; nalezo zezwi, umsindo. Uhlobo ngalunye ludinga uhlobo oluhlukile lwekhebula ngenxa yama-voltage ahlukene abawaphethe, ubude bawo, kanye nezidingo zabo zokuvikela.
Isinyathelo sokuqala ekukhetheni ikhebula elifanele ukunquma ukuthi udinga amandla noma uxhumano lwedatha (noma kokubili). Uma uhlelo lwakho lokusebenza ludinga kuphela uhlobo olulodwa lokuxhumana, ungaqhubeka nalolo hlobo, ngaphandle kokudinga ukuthenga izinhlobo eziningi ngesikhathi esisodwa!
Ikhebula lePlenum
Igama elithi " plenum " libhekisela emakamelweni omoya esakhiweni, njengalawo atholakala ezindlini ezingaphansi komhlaba kanye nasezindlini eziphansi. Ikhebula lohlobo lwe-plenum lisetshenziselwa ukuxhuma lezi zindawo ngoba alishisi futhi liyisicaba. Izintambo ezisicaba azivunyelwe ezikhungweni zedatha noma ezakhiweni zokuhlala ngenxa yokuthambekela kwazo kokuxakeka.
Patch panel
Iphaneli ye-patch iyihadiwe exhumanisa ikhebula lenethiwekhi nekhompyutha. Kunezinhlobo ezimbili zamaphaneli e-patch: amaphaneli e-patch namabhokisi e-cross-connect (aziwa nangokuthi amabhokisi e-punchdown). Iphaneli ye-patch ibalulekile ekufakweni kwezintambo ezihlelekile futhi iyisici esibalulekile ekuxhumaneni kwamakhompyutha.
Iphaneli ye-patch yibhokisi elinemigqa yama-port angasetshenziswa ukuxhuma izintambo kumadivayisi enethiwekhi afana nama-PC namaseva. Ibhokisi elixhumanisayo liqukethe izikhala eziningana zezintambo ezixhumanisayo, kodwa alifaki noma yiziphi izingxenye ze-elekthronikhi noma izifunda ezisebenzayo; lokhu kusho ukuthi uzodinga idivayisi ehlukile (njengeswishi ) ukuze uyisebenzise.
100% ithusi noma i-fiber uxhumano
Ukukhetha phakathi kwezintambo zethusi ne-fiber optic kuyindaba yokuzikhethela komuntu siqu. Zombili zinezinzuzo nezinkinga, kodwa amabhizinisi amaningi angahlangabezana nezidingo zawo nganoma iyiphi yazo. Ukuze uqonde kangcono ukuthi lezi zinketho zifanelana kanjani nezimo ezahlukene, ungabheka izihloko eziphathelene namanethiwekhi ekhompyutha.
Copper
I-Copper isetshenziswe kumanethiwekhi kusukela ekuqaleni kwayo, ngakho-ke iyaziwa futhi iqondwa ngochwepheshe abaningi. Futhi ishibhile kakhulu kunekhebula le-fiber optic, okwenza kube lula kwezinye izinkampani ukusebenzisa izixazululo zekhebula ezihlelekile emahhovisi azo noma ezikhungweni zedatha. Kodwa-ke, i-copper cabling ayisheshi njengezinhlelo ezisekelwe ku-fiber: ingadlulisela kuphela idatha ku-1 Gb/s (amagigabhithi ngomzuzwana), kuyilapho amazinga amasha afana ne-10GBASE-T evumela isivinini esingafika ku-10 Gbps ukuthi sizuzwe ngekhebuli yethusi.
I-fiber optic
Izintambo ze-fibre optic zinikeza umkhawulokudonsa omkhulu kakhulu kunezintambo zethusi zendabuko. Lokhu kuvumela amabhizinisi athembele kakhulu ekuxhumaneni kwe-inthanethi okusheshayo (njengalawo asebenzisa izinsizakalo zamafu) ukuthi azuze kakhulu ekuzisebenziseni esikhundleni sezinhlelo zezintambo zendabuko, njengoba ngeke abhekane nokuminyana ngenxa yomthamo omkhulu wethrafikhi, njengoba kungenzeka ngezintambo zocingo ezijwayelekile. Ngaphezu kwalokho, ukusungula izinto ezintsha okuqhubekayo ku-fiber optics kwandisa amakhono ayo nakakhulu.
Amapayipi ekhebula namathileyi
Ukufaka izintambo ezakhiwe ngendlela ehlelekile kuwubuciko. Kunezindlela ezimbili zokusebenzisa izintambo esakhiweni ngokwemithethonqubo yokuxhumana kwezakhiwo kanye namanethiwekhi e-ICT : amapayipi kanye namathreyi ekhebula. Amapayipi ayizipayipi zensimbi ezingafakwa ezindongeni, phansi, kanye nophahla lwesakhiwo. Angasetshenziswa kokubili izintambo zikagesi nezedatha, kodwa angathwala uhlobo olulodwa lwekhebula ngesikhathi.
Amathreyi ekhebula enziwe nge-aluminium noma ngensimbi, ngakho aqine ngokwanele ukusekela izinhlobo eziningi zamakhebula ngesikhathi esisodwa, kodwa futhi abiza kakhulu kunamapayipi ngoba adinga izinqubo zokufaka ezidinga umsebenzi omningi, njengokusika kube phansi ukhonkolo noma izigxobo zodonga (izisekelo zokhuni eziqondile ezibamba izindonga).
Amathreyi ekhebula nawo awasebenzi kahle nge-fiber optic cabling, njengoba lolu hlobo lwesisetshenziswa ludinga ukuvikeleka okwengeziwe ezicini zemvelo ezifana nomswakama noma izinga lokushisa elidlulele; Kodwa-ke, uma unesistimu yezokuxhumana endala ehlanganisa izintambo zethusi ngokuphelele, lokhu kungase kungabi nandaba kangako, inqobo nje uma ungenazo izinhlelo zokuyithuthukisa noma nini maduze.
Ungaba nenethiwekhi engcono ngokusebenzisa uhlobo olulungile lwekhebula ehlelekile
Isinyathelo sokuqala ukukhetha i-wiring efanele futhi uyifake ngendlela efanele, okusho ukuthi uqinisekise ukuthi izintambo zifakwe ngendlela ehlelekile futhi ehlelekile. Lokhu kuzokusiza ukuthi ugweme izinkinga ezinjengokulahleka kwesignali kanye nokuphazamiseka ngokuhamba kwesikhathi uma uzama ukwenza inethiwekhi yakho isebenze.
Uma usukhethile uhlobo lwekhebula oluzifanela kangcono izidingo zakho, ukufakwa kufanele kuqonde ngqo - vele ulandele lezi zinyathelo ezilula. Okokuqala, hambisa zonke izintambo ngamapayipi noma amathreyi ekhebula (uma kungenzeka). Bese uzixhuma ngqo kuzimbobo zazo kumaphaneli okuchibiyela noma amaswishi usebenzisa amathuluzi okushaya phansi noma izidladla; qiniseka ukuthi aweqi noma yiziphi izikhonkwane phakathi nale nqubo.
Okokugcina: hlola yonke into ngaphambi kokuqhubekela phambili nanoma yimuphi omunye umsebenzi! Awufuni ukumangala lapho wonke lawo mahora achithwa ukusetha konke ekugcineni ekhokha.
Isiphetho: Ikhebula lenethiwekhi elakhiwe
Sithemba ukuthi uthole lesi sihloko siwusizo futhi sikusize ufunde kabanzi mayelana nekhebula ehlelekile. Amanethiwekhi akhiwe ayindlela enhle yokuqinisekisa ukuthi ibhizinisi lakho liyaqhubeka nokusebenza kahle ngisho nalapho izinto ziba matasatasa. Uma udinga usizo ngenethiwekhi yakho noma ungathanda ulwazi olwengeziwe mayelana nokuthi singasiza kanjani, sicela usithinte namuhla.
