Kwihlabathi lothungelwano, iiswitshi zidlala indima ebalulekileyo ekuqhagamsheleni izixhobo nasekulawuleni ithrafikhi yedatha. Njengoko ubuchwepheshe butshintsha, iintlobo zeechweba ezikhoyo kwiiswitshi ziye zahluka, apho ii-fiber optic kunye neechweba zombane zezona zixhaphakileyo. Ukuqonda umahluko phakathi kwezi ntlobo zimbini zeechweba kubalulekile kwiinjineli zenethiwekhi kunye neengcali ze-IT xa kuyilwa kwaye kusetyenziswa iziseko zothungelwano ezisebenzayo.
Amazibuko ombane
Izikhuseli zombane kwiiswitshi zihlala zisebenzisa iintambo zobhedu, ezifana neentambo ezijijekileyo (umz., iCat5e, iCat6, iCat6a). Ezi zikhuseli zenzelwe ukudlulisa idatha kusetyenziswa imiqondiso yombane. Isikhuseli sombane esiqhelekileyo sisixhumi se-RJ-45, esisetyenziswa kakhulu kwiinethiwekhi ze-Ethernet.
Enye yezona nzuzo ziphambili zeeports zombane kukusebenza kakuhle kwazo. Iintambo zekopolo zihlala zibiza kancinci kunefayibha, nto leyo eyenza zibe lukhetho oludumileyo kwiinethiwekhi ezincinci neziphakathi. Ngaphezu koko, iiports zombane kulula ukuzifaka nokuzigcina kuba azidingi zakhono okanye izixhobo ezikhethekileyo ukuze zipheliswe.
Nangona kunjalo, amazibuko ombane anemida ngokubhekiselele kumgama wokudlulisa kunye ne-bandwidth. Iintambo zobhedu zihlala zinomgama ophezulu wokudlulisa omalunga neemitha ezili-100, emva koko kwenzeka ukonakala kwesiginali. Ngaphezu koko, amazibuko ombane asengozini enkulu yokuphazamiseka kwe-electromagnetic (EMI), okunokuchaphazela ukuthembeka kwedatha kunye nokusebenza kwenethiwekhi.
Izibuko elibonakalayo
Kwelinye icala, ii-fiber optic ports zisebenzisa ii-fiber optic cables ukuhambisa idatha ngendlela yemiqondiso yokukhanya. Ezi ports zenzelwe ukuhanjiswa kwedatha ngesantya esiphezulu kumgama omde, nto leyo eyenza ukuba zilungele iinethiwekhi ezinkulu zamashishini, amaziko edatha, kunye nezicelo zonxibelelwano. Ii-fiber optic ports ziza ngeendlela ezahlukeneyo, kuquka i-SFP (Small Form Factor Pluggable), i-SFP+, kunye ne-QSFP (Quad Small Form Factor Pluggable), nganye ixhasa amazinga edatha ahlukeneyo kunye nomgama wokudluliselwa.
Inzuzo ephambili yee-fiber optic ports kukukwazi kwazo ukudlulisa idatha kumgama omde (ukuya kuthi ga kwiikhilomitha ezininzi) ngaphandle kokulahleka okukhulu kwesiginali. Oku kuzenza zilungele ukuqhagamshela iindawo ezikude okanye usetyenziso lwe-bandwidth ephezulu njengokusasazwa kwevidiyo kunye ne-cloud computing. Ngaphezu koko, iintambo ze-fiber optic azichaphazeleki kukuphazamiseka kwe-electromagnetic (EMI), zibonelela ngonxibelelwano oluzinzileyo noluthembekileyo.
Nangona kunjalo, ii-fiber optic ports nazo zineengxaki zazo. Ixabiso lokuqala leentambo ze-fiber optic kunye nezixhobo ezinxulumene nazo linokuba phezulu kakhulu kunezisombululo zentambo yobhedu. Ngaphezu koko, ukufaka nokuphelisa iintambo ze-fiber optic kufuna izakhono ezikhethekileyo kunye nezixhobo, nto leyo eyandisa ixesha kunye neendleko zokusetyenziswa.
Umahluko ophambili
Isixhobo sokudlulisa: Isango lombane lisebenzisa intambo yobhedu, kwaye isango le-optical lisebenzisa intambo ye-fiber optic.
Umgama: Iizibuko zombane zilinganiselwe kwiimitha ezili-100, ngelixa iizibuko ezibonakalayo zinokudlulisela idatha kwiikhilomitha ezininzi.
I-bandwidth: Ii-fiber optic ports zihlala zixhasa i-bandwidth ephezulu kunee-electrical ports, nto leyo ezenza zilungele ukusetyenziswa kwezicelo ezifunwa kakhulu.
Ixabiso: Izikhumulo zombane zihlala zibiza kancinci xa kufikwa kumgama omfutshane, ngelixa izikhumulo ze-optical zinokubangela iindleko zokuqala eziphezulu kodwa zinokubonelela ngeenzuzo zexesha elide kwiinethiwekhi ezinkulu.
Ukuphazamiseka: Iiports ze-optical azichaphazeleki kukuphazamiseka kwe-electromagnetic, ngelixa iiports zombane zichaphazeleka yi-EMI.
ukuququmbela
Ngamafutshane, ukhetho phakathi kwe-fiber kunye ne-electrical ports kwiswitshi luxhomekeke kwizinto ezahlukeneyo, kuquka iimfuno ezithile zenethiwekhi, imida yohlahlo lwabiwo-mali, kunye nokusebenza okufunekayo. Kwiinethiwekhi ezincinci ezinemigama emincinci, ii-electrical ports zinokwanela. Nangona kunjalo, kwiinethiwekhi ezinkulu nezisebenza kakuhle ezifuna uqhagamshelo lomgama omde, ii-fiber ports zezona zikhetho zilungileyo. Ukuqonda la mahluko kubalulekile ekwenzeni izigqibo ezinolwazi kuyilo lwenethiwekhi kunye nokusetyenziswa kwayo.
