II-100M i-fiber optical transceiver(eyaziwa nangokuthi i-100M photoelectric converter) isiguquli se-Ethernet esisheshayo. I-fiber optic transceiver ihambisana ngokugcwele namazinga e-IEEE802.3, IEEE802.3u, kanye ne-IEEE802.1d. Isekela izindlela ezintathu zokusebenza: i-duplex egcwele, i-half duplex, ne-adaptive.
I-Gigabit optical fiber transceiver(eyaziwa nangokuthi i-photoelectric converter) iyi-Ethernet esheshayo enezinga lokudluliswa kwedatha elingu-1Gbps. Isasebenzisa indlela yokulawula ukufinyelela kwe-CSMA/CD futhi iyahambisana ne-Ethernet ekhona. Ngosekelo lwesistimu yezintambo , Engakwazi ukuthuthukisa ngokushelela i-Fast Ethernet yasekuqaleni futhi ivikele ngokugcwele utshalomali lwangempela lwabasebenzisi.
Ubuchwepheshe benethiwekhi ye-Gigabit buye baba ubuchwepheshe obukhethwayo bamanethiwekhi amasha nokwakhiwa kabusha. Nakuba izidingo zokusebenza zesistimu yezintambo ezihlanganisiwe nazo zithuthukisiwe, inikeza ukusebenziseka kwabasebenzisi kanye nokuthuthukiswa okuzayo.
Izinga le-Gigabit Ethernet lenziwa yi-IEEE 802.3, futhi kukhona amazinga amabili okufaka izintambo angu-802.3z no-802.3ab. Phakathi kwazo, i-802.3ab iyindinganiso yezintambo esekelwe kupheya esontekile, kusetshenziswa amapheya angu-4 eSigaba 5 UTP, futhi ibanga lokudlulisela eliphakeme lingu-100m. Futhi i-802.3z iyindinganiso esekelwe ku-Fiber Channel, futhi kunezinhlobo ezintathu zemidiya ezisetshenzisiwe:
a) Ukucaciswa kwe-1000Base-LX: Lokhu kucaciswa kubhekisela kumapharamitha we-multimode kanye ne-fibre yemodi eyodwa esetshenziswa ebangeni elide. Phakathi kwazo, ibanga lokudlulisela le-multi-mode fiber liyi-300 (amamitha angu-550, futhi ibanga lokudlulisela le-fiber yemodi eyodwa ingamamitha angu-3000.）Ukucaciswa kudinga ukusetshenziswa kwama-laser transceiver amagagasi amade abiza kakhulu.
b) Ukucaciswa kwe-1000Base-SX: Lokhu kucaciswa yimingcele ye-multimode fiber esetshenziswa ebangeni elifushane. Isebenzisa i-multimode fiber kanye ne-CD ye-shortwave ebiza kancane (i-compact disc) noma amalaser e-VCSEL, futhi ibanga layo lokudlulisela lingamamitha angu-300 (amamitha angu-550.)
Amazwana: I-Gigabit optical converter iwuhlobo lwesiguquli sesignali esisetshenziswa ukuguqula isignali kagesi yekhompyutha ye-Gigabit Ethernet ibe isignali yokubona. Ihambisana nezinga le-IEEE802.3z/AB; isici sayo ichweba likagesi Isignali ihambisana ne-1000Base-T, engakwazi ukuzivumelanisa ngokwayo ngomugqa oqondile / umugqa we-crossover; futhi ingaba kumodi ye-duplex egcwele/isigamu esiyiduplex.
Njengamanje, kusetshenziswe ama-megabits angaphezu kwekhulu, futhi ambalwa ama-gigabit asetshenzisiwe, kodwa manje amanani entengo ye-megabits ne-gigabit asondela kancane kancane. Uma uyibheka ngombono wesikhathi eside, kunconywa ukusebenzisa i-gigabiti-fiber optic transceivers.
Uma inethiwekhi yamanje ingenazo izidingo ezikhethekile, ngisho noma izodlulisa ividiyo enencazelo ephezulu noma inani elikhulu lokudluliswa kwedatha, inethiwekhi ye-100M yanele.
Ama-transceiver optical angu-100M ashibhile kunama-gigabit optical transceivers, futhi ama-transceiver optical angu-100M nawo azosetshenziswa ngokwezindleko. Kodwa-ke, uma inethiwekhi yendawo yendawo iyinethiwekhi ye-gigabit, ukusetshenziswa kwama-gigabit transceivers kungcono kakhulu kune-transceiver engu-100M.
Isifinyezo: Ama-transceivers e-Fast and Gigabit fiber optic anomsebenzi ofanayo, asetshenziselwa ukuthola amasignali okukhanya, kodwa umkhawulokudonsa wabo uhlukile, futhi isivinini se-Gigabit siyashesha.
