I-Transceiver

I-Ethernet Fiber Optic Transceiver.
I-fiber optic transceiver ye-Ethernet yindlela yokuguqula indlela emibini ecacileyo enikezela ngezibonakaliso zedatha ye-Ethernet kwiimpawu zedatha ye-fiber optic, evumela ukuba iimpawu ze-Ethernet zidluliselwe kwimigca ye-fiber optic ukuba iphule umda we-100m wokuhambisa umgama, okwenza i-network ye-Ethernet ifikeleleke kakhulu.Unxibelelwano lwedatha yeFiber optic ineempawu zonxibelelwano olude lomgama, umthamo omkhulu wedatha yonxibelelwano, kwaye ayinakuchaphazeleka.
I-Optical fiber ingene kuzo zonke iinkalo zobomi kuwo onke amanqanaba.Njengoko iinkqubo zokuqala zenethiwekhi zisekelwe kunxibelelwano lwentambo, ukuvela kwe-fiber optic transceivers kuqinisekisa ukuba izibonakaliso zombane kunye neempawu ze-fiber optic ziyakwazi ukuguqulwa komnye nomnye ngokutyibilikayo kwaye zifanelekile kwi-telecommunications, usasazo, i-broadband networks, kunye nezinye iindawo ze-Ethernet ezifuna ukuphakama. isantya, ukugcwala kwedatha ephezulu, kunye nokusebenza okuphezulu kunye nokuthembeka.

I-Ethernet PHY

Yintoni i-Ethernet PHY:
I-PHY (Enyameni), enokuthiwa yi-Port Physical Layer ngesiTshayina, sisishunqulelo esiqhelekileyo semodeli ye-OSI umaleko womzimba.Kwaye i-Ethernet sisixhobo esisebenzisa umaleko womzimba wemodeli ye-OSI.I-Ethernet PHY yitshiphu ethumela kwaye ifumane iifreyimu zedatha ye-Ethernet (iifreyimu).

Imisebenzi ebalulekileyo

1. Ukuthumela idatha: Xa i-PHY ithumela idatha, ifumana idatha ehanjiswe yi-MAC.Emva koko iguqula i-parallel data kwi-serial stream data kwaye emva koko i-encode data ngokwemigaqo ye-encoding ye-physical layer.Ekugqibeleni, iba ngumqondiso we-analog kwaye ithumela idatha ngaphandle.2.
2. I-PHY nayo inomsebenzi obalulekileyo wokuphumeza inxalenye ye-CSMA/CD function.3.
3. I-PHY ikwabonelela ngomsebenzi obalulekileyo wokudibanisa kunye nesixhobo kwelinye icala kwaye ibonise isimo sayo soxhumo lwangoku kunye nesimo sokusebenza ngokusebenzisa ii-LED.Xa sidibanisa ikhadi lomnatha kwintambo, i-PHY isoloko ibetha imiqondiso ukuze ibone ubukho bezixhobo kwelinye icala, ezinxibelelana kunye "kulwimi" oluqhelekileyo ukuxoxisana kunye nokumisela isantya soqhagamshelwano, imowudi ye-duplex, nokuba sebenzisa ulawulo lokuhamba njalo njalo.Ngokuqhelekileyo, isiphumo solu thethwano sesona santya siphezulu kunye neyona ndlela igqwesileyo ye-duplex enokuxhaswa zizo zombini izixhobo.
