II-100M i-fiber optical transceiver(ekwaziwa ngokuba yi-100M photoelectric converter) sisiguquli se-Ethernet esikhawulezayo. I-fiber optic transceiver ihambelana ngokupheleleyo ne-IEEE802.3, IEEE802.3u, kunye nemigangatho ye-IEEE802.1d. Ixhasa iindlela ezintathu zokusebenza: i-duplex epheleleyo, i-half duplex, kunye ne-adaptive.
I-Gigabit optical fiber transceiver(ekwabizwa ngokuba yi-photoelectric converter) yi-Ethernet ekhawulezayo enezinga lokudluliselwa kwedatha ye-1Gbps. Isasebenzisa indlela yokulawula ukufikelela kwe-CSMA/CD kwaye iyahambelana ne-Ethernet ekhoyo. Ngenkxaso yenkqubo yocingo , Enokuphucula ngokukhawuleza i-Fast Ethernet yasekuqaleni kwaye ikhusele ngokupheleleyo utyalo-mali lwangaphambili lwabasebenzisi.
Itekhnoloji yenethiwekhi yeGigabit iye yaba yitekhnoloji ekhethiweyo yothungelwano olutsha kunye nokwakhiwa kwakhona. Nangona iimfuno zokusebenza kwenkqubo yocingo ehlanganisiweyo nazo ziphuculwe, ibonelela ngokulula ukusetyenziswa kwabasebenzisi kunye nokuphuculwa kwexesha elizayo.
Umgangatho we-Gigabit Ethernet wenziwa yi-IEEE 802.3, kwaye kukho imigangatho emibini ye-wiring ye-802.3z kunye ne-802.3ab. Phakathi kwabo, i-802.3ab ngumgangatho we-wiring esekelwe kwi-pair twisted pair, usebenzisa ii-4 pairs zeCandelo le-5 UTP, kwaye umgama omkhulu wokuhanjiswa ngu-100m. Kwaye i-802.3z ngumgangatho osekelwe kwiFiber Channel, kwaye kukho iintlobo ezintathu zemidiya ezisetyenzisiweyo:
a) Ukucaciswa kwe-1000Base-LX: Le nkcazo ibhekiselele kwiiparamitha ze-multimode kunye ne-fiber-mode-mode eyodwa esetyenziswe kumgama omde. Phakathi kwazo, umgama wothumelo lwefayibha yeendlela ezininzi yi-300 (iimitha ezingama-550, kwaye umgama wothumelo lwefiber yendlela enye yimitha ye-3000.）Ingcaciso ifuna ukusetyenziswa kwee-transceivers ze-laser ezine-wave ezibiza kakhulu.
b) Ukucaciswa kwe-1000Base-SX: Le nkcazo yiparameters yefiber ye-multimode esetyenziswe kumgama omfutshane. Isebenzisa i-multimode fiber kunye ne-CD ye-shortwave enexabiso eliphantsi (i-compact disc) okanye i-laser ye-VCSEL, kwaye umgama wayo wokuhambisa yi-300 (550 yeemitha.)
Amanqaku: I-Gigabit optical converter luhlobo loguqulo lwe-optical optical olusetyenziselwa ukuguqula umqondiso wombane wekhompyutheni ye-Gigabit Ethernet ibe ngumqondiso we-optical. Ihambelana nomgangatho we-IEEE802.3z/AB; uphawu lwayo yi-port yombane Umqondiso uhambelana ne-1000Base-T, enokuthi ikwazi ukuziqhelanisa ngomgca ochanekileyo / umgca we-crossover; inokuba kwimowudi epheleleyo ye-duplex/half duplex.
Okwangoku, kusetyenziswa ngaphezu kwekhulu leemegabhithi, kwaye zimbalwa iigigabhithi ezisetyenziswayo, kodwa ngoku amaxabiso eemegabhithi ezilikhulu kunye negigabhithi asondela ngokuthe ngcembe. Ukuba ukhangele kwimbono yexesha elide, kuyacetyiswa ukuba usebenzise i-gigabiti-fiber optic transceivers.
Ukuba inethiwekhi yangoku ayinayo iimfuno ezikhethekileyo, nokuba ngaba idlulisa i-high-definition yevidiyo okanye inani elikhulu lokudluliselwa kwedatha, inethiwekhi ye-100M yanele.
I-100M ii-transceivers optical transceivers zixabiso eliphantsi kune-gigabit optical transceivers, kwaye i-100M i-transceivers optical iya kusetyenziswa ngokwexabiso. Nangona kunjalo, ukuba inethiwekhi yendawo yendawo yinethiwekhi yegigabit, ukusetyenziswa kwe-gigabit transceivers kungcono kakhulu kune-100M ye-transceiver.
Isishwankathelo: I-Fast and Gigabit fiber optic transceivers inomsebenzi ofanayo, isetyenziselwa ukufumana iimpawu zokukhanya, kodwa i-bandwidth yazo iyahluka, kwaye isivinini seGigabit sikhawuleza.
