Ii-fiber optic transceiveryiyunithi yokuguqula imidiya ye-Ethernet etshintshisa umgama omfutshane ojijekileyo wemiqondiso yombane kunye nemiqondiso yokubona ekude. Ikwabizwa ngokuba yi-photoelectric converter kwiindawo ezininzi.Imveliso isetyenziswa ngokubanzi kwindawo yothungelwano yokwenene apho intambo ye-Ethernet ayinakugquma kwaye i-fiber optical kufuneka isetyenziswe ukwandisa umgama wothumelo, kwaye idla ngokubekwa kwi-access layer application. inethiwekhi yendawo yemetropolitan yefiber optical fiber; ngexesha elifanayo, kunceda ukudibanisa i-mile yokugqibela ye-fiber optical kwisixeko. Uthungelwano lwengingqi kunye nothungelwano lwangaphandle nazo zidlale indima enkulu.

Ukubeka nje, indima ye-fiber optic transceiver kukuguqulwa okufanayo phakathi kweempawu zokukhanya kunye neempawu zombane. Isignali ye-optical igalelo kwi-port optical, kwaye isibonakaliso sombane siphuma kwi-port yombane (i-RJ45 i-crystal head interface eqhelekileyo), kunye ne-vice versa.Inkqubo i-roughly: ukuguqula izibonakaliso zombane kwiimpawu ze-optical, ukuhambisa nge-fiber optical. kwaye emva koko uguqule iisignali zamehlo zibe ziimpawu zombane kwelinye icala, kwaye emva koko uzidibanise nazoiirotha, iiswitshikunye nezinye izixhobo.

Luluphi ulwahlulo lwee-fiber optic transceivers

Ii-engile ezahlukeneyo zokujonga zenza abantu babe nokuqonda okwahlukileyo kwee-transceivers zefiber optic:

Ngokomzekelo, ngokwezinga lokudluliselwa, ihlukaniswe yaba yi-10M enye, i-100M ye-fiber optic transceivers,I-10/100M i-adaptive fibre optic transceiverskunye ne-1000M i-fiber optic transceivers;

Ngokwendlela yokusebenza, ihlukaniswe kwii-transceivers ze-fiber optic ezisebenza kwi-fiber optic layer kunye ne-fiber optic transceivers esebenza kwi-data link layer;

Ukusuka kwimbono yesakhiwo, yahlulwe kwi-desktop (i-stand-alone) i-fiber optic transceivers kunye ne-rack-mounted fiber optic transceivers;

Ngokweentsinga zokufikelela ezahlukeneyo, kukho amagama amabini: i-fiber transceiver ye-multi-mode kunye ne-fiber-mode-fiber transceiver.

Ukongeza, kukho i-fiber optic transceivers enye-fiber kunyeiitransceiver zefiber optic ezimbini, i-fiber optic transceivers eyakhelwe ngaphakathi kunye ne-fiber optic transceivers yamandla angaphandle, kunye ne-fiber optic transceivers elawulwayo kunye ne-fiber optic transceivers engalawulwayo.

I-Fiber optic transceivers iphula umda we-100-meter ye-Ethernet cables kwi-data transmission, ixhomekeke kwi-high-performance switching chips kunye ne-buffers enkulu, ngelixa ufezekisela ngokwenene ukuhanjiswa kunye nokusebenza kokutshintsha, ikwabonelela nge-traffic elinganiselayo, ukuhlukaniswa kweengxabano kunye nokuziphatha. Ukufunyanwa kwempazamo kunye neminye imisebenzi iqinisekisa ukhuseleko oluphezulu kunye nokuzinza ngexesha lokuhanjiswa kwedatha.

Uphi uluhlu lwesicelo se-fiber optic transceivers

Ngokwenene, i-transceiver ye-fiber optical igqiba kuphela ukuguqulwa kwedatha phakathi kwemidiya eyahlukeneyo, enokuqonda uxhulumaniso phakathi kwezimbini.iiswitshiokanye iikhomputha ngaphakathi kwe-0-120Km, kodwa isicelo sangempela sinokwandiswa okungakumbi.

1. Qonda unxibelelwano phakathiiiswitshi.
2. Qonda unxibelelwano phakathi kwetshintshakunye nekhompyuter.
3. Qonda unxibelelwano phakathi kweekhompyuter.
4. I-transmission relay: Xa umgama wothumelo wangempela udlula umgama wothumelo oqhelekileyo we-transceiver, ngakumbi xa umgama wothumelo wangempela udlula i-120Km, ukuba iimeko zesayithi zivumela, sebenzisa i-2 transceivers kwi-relay-back-back-relay okanye ukukhanya-to-optical conversion. i-relay sisisombululo esinendleko kakhulu.
5. Ukuguqulwa kwe-multi-mode eyodwa: Xa uxhulumaniso lwefayibha enye-multi-mode iyadingeka phakathi kwamanethiwekhi, i-converter ye-multi-mode mode ingasetyenziselwa ukudibanisa, esombulula ingxaki yokuguqulwa kwefayibha enye-mode.
6. Ukuhanjiswa kwe-Wavelength division multiplexing transmission: Xa izibonelelo zentambo ye-fiber ye-optical umgama omde zingonelanga, ukwenzela ukwandisa izinga lokusetyenziswa kwentambo ye-optical kunye nokunciphisa iindleko, i-transceiver kunye ne-multiplexer ye-wavelength division ingasetyenziselwa kunye ukuhambisa iziteshi ezimbini ze-wavelength. ulwazi kwiperi enye yeentsinga zamehlo.
