Isiguquli sefoto sombane sinokuphucula ngokutyibilikayo i-Ethernet yantlandlolo ngokukhawuleza kwaye ikhusele ngokupheleleyo izibonelelo zenethiwekhi zabasebenzisi.Isenokuthiwa yi-optical fiber transceiver.I-photoelectric converter inokuqonda ukudibanisa phakathi kokutshintsha kunye nekhompyutheni, inokusetyenziswa njenge-relay yokudlulisa, kwaye inokwenza uguqulelo lwe-multi-mode enye.Ngethuba lenkqubo yesicelo se-transceiver ye-fiber optical, kufuneka kuthathelwe ingqalelo ukuyigcina, ukuze kwandiswe ubomi benkonzo yomatshini.
Yintoni umsebenzi we-photoelectric converter?
1. I-photoelectric converter ayikwazi nje ukuqonda ukudibanisa phakathi kokutshintsha kunye nokutshintsha, kodwa kunye nokudibanisa phakathi kokutshintsha kunye nekhompyutheni, kunye nokudibanisa phakathi kwekhompyutheni kunye nekhompyutheni.
2. Ukuhanjiswa kwe-relay, xa umgama wothumelo wangempela udlula umgama ogqithisiweyo we-transceiver, ngakumbi xa umgama wothumelo wangempela udlula i-120Km, ukuba iimeko zesayithi zivumela, sebenzisa i-2 transceivers kwi-relay-back-back okanye sebenzisa ukukhanya- I-Optical converters. kuba ukuhanjiswa sisisombululo esixabisa kakhulu.
3. Uguqulo lwendlela enye-emininzi.Xa uxhulumaniso lwefiber ye-multi-mode enye lufunekayo phakathi kwamanethiwekhi, i-converter enye-multi-mode ingasetyenziselwa ukudibanisa, okusombulula ingxaki yokuguqulwa kwefayibha enye-mode.
4. I-Wavelength division multiplexing transmission.Xa izibonelelo zentambo ye-fiber optical umgama omde ayanelanga, ukwenzela ukwandisa izinga lokusetyenziswa kwentambo ye-optical kunye nokunciphisa iindleko, i-transceiver kunye ne-wavelength division multiplexer ingasetyenziselwa ukuhambisa iziteshi ezimbini zolwazi kwisibini esifanayo. zemicu optical.
Uyigcina njani i-fiber optic transceiver?
1. Ekusetyenzisweni kwe-fiber optic transceivers, kuyimfuneko ukuqinisekisa ukuba iimodyuli ze-laser kunye neemodyuli zokuguqulwa kwe-photoelectric ze-transceiver optical ziqhubeka ngokuqhubekayo kwaye ngokuqhelekileyo zinikwe amandla, kwaye impembelelo ye-pulse current current igwenywe, ngoko ayifanelekanga. tshintsha umatshini rhoqo.Igumbi lekhompyutheni eliphambili eliphambili apho i-transceivers optical igxininiswe kunye ne-1550nm optical transmitter optical amplifier set point kufuneka ixhotyiswe nge-UPS power supply ukukhusela amacandelo e-laser kunye nokukhusela imodyuli yokuguqula i-photoelectric ukuba yonakaliswe yi-pulse yangoku.
2. Indawo yokusebenza enomoya, ekhupha ubushushu, ingqina ukufuma, kwaye icocekile kufuneka igcinwe ngexesha lokusetyenziswa kwefiber optic transceivers??Icandelo le-laser ye-optical transmitter yintliziyo yesixhobo kwaye ifuna iimeko eziphezulu zokusebenza.Ukuze kuqinisekiswe ukusebenza okuqhelekileyo kwezixhobo, umenzi we-A ifriji kunye nenkqubo yokulahla ukushisa ifakwe kwisixhobo, kodwa xa ubushushu be-ambient budlula uluhlu oluvumelekileyo, izixhobo azikwazi ukusebenza ngokuqhelekileyo.Ngoko ke, kwixesha elitshisayo, xa igumbi lekhompyutheni eliphakathi linezixhobo ezininzi zokufudumeza kunye neemeko zokungena komoya ezimbi kunye neemeko zokutshatyalaliswa kobushushu, kukulungele ukufaka inkqubo ye-Air conditioning ukuqinisekisa ukusebenza okuqhelekileyo kwe-transceiver optical.I-diameter esebenzayo ye-fiber core ikwinqanaba le-micron.Uthuli oluncinci olungena kwi-interface esebenzayo ye-pigtail luya kuthintela ukusasazeka kwezibonakaliso ze-optical, kubangela ukuhla okukhulu kwamandla optical kunye nokunciphisa umlinganiselo we-signal-to-noise yenkqubo.Olu hlobo lwezinga lokungaphumeleli limalunga ne-50%, ngoko ke igumbi lekhompyutha Ukucoceka kubaluleke kakhulu.
3. Ukusetyenziswa kwe-fiber optic transceivers kufuneka ibekwe esweni kwaye irekhodwe.I-transceiver ebonakalayo ixhotyiswe nge-microprocessor ukubeka iliso kwimo yokusebenza yangaphakathi yenkqubo kwaye iqokelele iiparitha ezahlukeneyo zokusebenza zemodyuli, kwaye ibonise ngokubonakalayo ngenkqubo yokubonisa i-LED kunye neVFD, ukwenzela ukukhumbuza ixabiso ngexesha labasebenzi, i-transmitter optical ixhotyiswe nge-alam evakalayo kunye neyokubonayo.Ngethuba nje abasebenzi bezolondolozo banquma isizathu sesiphoso ngokwemilinganiselo yokusebenza kwaye bajongane nayo ngexesha, ukusebenza okuqhelekileyo kwenkqubo kunokuqinisekiswa.
