iswitchi se-nethiwekh ya-fiber optic

Isikhombisi sekhelwe yamadatashini sikhombisa njengokuchazwa okubalulekile kumakethe amadatashini esikhathi esisha, kuxhasa ukuthumela data kakhulu ngokusebenzisa ikhabeli lekhelwe yamadatashini. Lolu rhamawuzi oluphambene neyodwa lisebenza ngokuthumela amapakethi edata phambi kwezinye izinkinobho zokusebenzisa imithwako yesibhedlela endaweni yezo zokusebenzisa i-electrical signals. Isikhombisi senquma amapakethi edata ongenayo bese licathula kuzindlela ezifanele ngokushesha nokucophelela. Lisebenza ku data link layer ye model ye-OSI, isikhombisi sekhelwe yamadatashini singasebenzela amanye amakhonke okuxhumana noma ngaphansi kwezinga eliphezulu, licophelela izinhloso ezingenakukhona ukusetshenziswa kwedatha. Lezi sikhombisi zinezinhlobo ezahlukene zemibandela, kusuka kwi-8-port models embhabheni ukuze kube ngu-48-port noma ngaphezulu, kuhlabezela ezinhlobweni ezahlukene nezinga lokuhlanganisa. Sicophelela amakhanda amabili wekhelwe, kungcono ukuthi khelwe enye injini (single-mode) nekhelwe ezimbili (multi-mode), okwenza kube uyilo lwamanye amakethe amadatashini. Iziphumo ezinhle like VLAN support, Quality of Service (QoS) management, ne-port mirroring zenhance network control and monitoring capabilities. Lezi sikhombisi esisha calethwa futhi kuzo i-manage interfaces ezinhle, ekuvumela abasebenzisi ukugcina, ukujonga, nokulungisa imiphatlalo yekheli.

Iziswitchi zokuxhumana ngemifula yenxenye yamanzi zenkosi kuzithunyelwa izintelo eziningi ezingcono ezaqoqwa ngokweqile kuzindlela zokuxhumana zamanzi nezindawo zasegolide. Okokuqala, bezinikeza ukukhanya nokwenene kwamanani okuphezulu, ekuvumela ukuthumela datha ngamathemu amaningi ayingaphansi kwalokho akungenayo maningi wamanzi aphumelelwe ngezinhlelo zokuxhumana ezijwayelekile. Lokhu kwenza kube lula ukusebenzisa izicelo ezikhulisiwe datha njengekuhlelwa kwebhideo, ukusebenzisa i-cloud, nokusebenza datha ngokushesha. Iziswitchi zenza into engiyileyo yokuthula, noma kungabi khona ukungcola komkhawulo emkhathini mide, okwenza kube yimali yezindlela zokuxhumana ezikhulu. Iziphumo zabo ezingenakuthinte umoya weqile esimweni semikhwelo elekthronikhi kuyizinye izinto ezingasemngcipheni iziswitchi zokuxhumana. Kuhlinzekile, iziswitchi zemifula yenxenye yamanzi zenkosi kuzinikeza ukuphephelwa okuningi kuhluka kudatha, ngoba imifula yenxenye yamanzi ingasingathinteki ngokwengaziwa. Bezifake futhi ukusebenza ngokwehlanzekile, bethola amandla angaphezu kwalokho akungenayo iziswitchi zokuxhumana ezijwayelekile aze bathola amakhetho amangeni, okwenza kube lula ukubilinda kanye nokusebenza. Ukuthuthukiswa kweziswitchi kuvumela abasebenzisi ukuthuthukisa inkosika yazo ngokwehlukahluka kwezidingo, ngaphandle kokuthinta ukusebenza noma ukudinga ukuhlukaniswa kabili komfanelo. Izidingo zokulungisa kahle kudinga phansi kunezinye iziswitchi zokuxhumana, okwenza ukuba kudinga amandla angaphansi kwezinye izindlela. Iziswitchi zenza amatekeli amaningi olawulwa kwekhelini, ekuvumela ukulawula ngokucophelela kwekhelini kanye nokuqashwa amathemu. Ukuze kuthunyelwe nezinhlelo zokuxhumana ezisebenzayo kanye nezinhlelo ezijwayelekile, kuthunyelwa ukuthi kuthunyelwe nezinhlelo zasegolide aze kune indlela ehleleneyo yezenzo eziza.

Ukusebenza okungafaniyo nokukhula

Iifibha optic enetwork switches zinikeza iimetric eokusebenza eziphezulu kakhulu ezithiwa ngaphandle kwesicelo samathuba. Le ndiviso ingaba nenkqubo yokuthumela idatha kuspeedi ya-100 Gbps ngamagqqa, neezona zintloko ezahlukeneyo eziquka ukuba phezulu. Le spidi elikhulu le nto iyenzeka ngokusebenzisa itekhnoloji ye-optical efihla isiqinisekiso se-elekthrisithi kuimpawu zelight, ekuvumela ukuthumelana ngokusheshayo. Le switch zikhuphela le spidi phezulu ngokwehlulekileyo yokutshelwa, ngokuchazwe kwiimikrosecond, ukunika inkxaso ethubelene nomsebenzi wezithuba. Iindawo zazo ukulawulwa kwezilwanyana ezininzi ezingaphezulu ngaphakathi akukho kuphula kwezisebenza kuyenza kube luncedo olukhulu kwiindawo zedatha, amanetwork asekhaya, kunye nezithuba lokusebenza ngokuphezulu.

Amalayithi Asemandla

Ukusekwa kuyindlela ebalulekile yokusebenza kwamadivayisi wekhonkco lefayibhile, enezinhlanganisela eziningi zokuphepha ngempumelelo. Le divayisi zenhloso ye- access control engeke yokuqiniseka ukuthatha iqembu elingenhla lemandla nekhonkco lasegmentiwe ngeVLANs. Iziphropathi ezifanele zakhiwo lefayibhile zenokuba yinkimbinkimbi ukuthinte noma ukulanda, ngoba yilapho amandla okuthola fayibhile ithathwa khona isikhathi esifewa sengculiso esingaba yimalipha esiyokwaziwa ngokushesha. Imithetho echazwe enciphanyayo iyagcina ulayiso oluthunyelwe kudivayisi lithathe isicelo sokuphepha, nangabe nemigca yokugcina izindikelo ezinxulumene nezinkinga ezingavumelekile noma izindleko zokusekwa.

Imigomo Eningi Yokuphathwa

Iindlela zokuphatha izwitchi zexesha lefiber optic zinika iingcambu ukwakhelwa ngokupheleleyo kwekhathini labo. Ngokusebenzisa iifayili ezivulekileyo kunye neenzile zokumandela, ezi switch ziya kugcinwa ingcaciso ejikeleze ngokusebenza kwekhathi, imeko yepoynti kunye nokucoca kwegida. Iindlela zakumkhiwo weQoS (Quality of Service) zenza ukuba kube lula ukukhetha intlawulo egqithisweyo kwegida ephuhlileyo, ukuze kugcinwe ukusebenza okupheleleyo kwiimeko ebaluleke. Ezi switch aziyophakamisa ngeendlela zokuphathwa ezahlukeneyo, ngokungxothwa kukaSNMP, ukunikeza ukuxeshwa kwazo neempawu zokuphathwa zeekhathi. Iindlela zokuseta ngokuzenzekelayo zenza inkulu ukubekwa kwayo kunye neendlela zokulungisa amathambo.
