Esikhathini sedatha enkulu, kunezinhlelo zokusebenza eziphakeme kakhulu futhi ezinomkhawulokudonsa ophezulu.Ngalesi sikhathi, ikhebuli ye-passive optical noma isistimu yekhebula esekwe ethusi ibonakala yeluliwe.Ukuze kuqinisekiswe ukusimama nokusebenzisa okuguquguqukayo kokudlulisela, abasebenzisi badinga ngokuphuthumayo uhlobo olusha lomkhiqizo njengendlela yokudlulisela eyinhloko yesikhungo sekhompyutha esisebenza kahle kakhulu nesedatha.Kulokhu, kuvele imikhiqizo yekhebula elibonakalayo elisebenzayo.
Uma kuqhathaniswa nezintambo zendabuko, izintambo ezibonakalayo ezisebenzayo zinezinzuzo eziningi, njengezinga eliphezulu lokudlulisela, ibanga elide lokudlulisela, ukusetshenziswa kwamandla aphansi, ukusetshenziswa okulula, njll. Zingasiza imishini yokuxhumana ukuba ijabulele izinzuzo ezinkulu zokudlulisa amehlo, futhi ziyizintambo ezifanele zokudlulisela izikhungo zedatha, ugesi wabathengi neminye imikhakha.
Ngomkhuba ongenakuhlehliswa "we-optical advance kanye ne-copper retreat", ikusasa kuzoba inkathi "yenethiwekhi ye-all-optical", kanye nobuchwepheshe bekhebula elibonakalayo elisebenzayo lizongena kuwo wonke amagumbi emakethe yokuxhumana ngesivinini esikhulu.
Ukubukeka kwekhebula le-Optical esebenzayo i-AOC kufana nalokhu kwe-DAC, kodwa imodi yokudlulisela kanye nemvelo yohlelo lokusebenza kuhlukile.
Kunezinhlobo ezine zekhebula elibonakalayo elisebenzayo i-AOC: 10G SFP+AOC, 25G SFP28 AOC, 40G QSFP+AOC kanye ne-100G QSFP28 AOC.Umehluko wabo omkhulu ijubane elihlukile.
Isakhiwo Nesiginali Yokudlulisa Imodi
Intambo yokubona esebenzayo i-AOC isebenzisa isigaba sekhebula yokubona ukuxhuma ama-transceiver amabili okubona.Ukunikezwa kwamandla kwangaphandle kusetshenziselwa ukudluliswa kwesignali.Imodi yokudlulisela ingukuguqulwa kukagesi-optical-electric.Isignali kagesi iguqulwa ibe isignali yokubona kusixhumi esingu-A-end.Isignali ye-optical ibe isidluliselwa kusixhumi se-B-end ngekhebula le-optical eliphakathi nendawo, bese isignali yokubona iguqulwa ibe isignali kagesi kusixhumi se-B-end.
Izici Nezinzuzo
Ikhebula le-Optical elisebenzayo i-AOC inezici zokusetshenziswa kwamandla aphansi, usayizi omncane, isisindo esilula kanye nokushabalaliswa kokushisa okuqinile.Uma iqhathaniswa nentambo yethusi, inebanga elide lokudlulisela (kufika ku-100~300 m) nokusebenza okungcono kokudlulisela.Uma kuqhathaniswa ne-module optical, ikhebula le-optical elisebenzayo alinayo inkinga ye-interface engcolile, ethuthukisa kakhulu ukuzinza nokuthembeka kwesistimu futhi inciphise izindleko zokuphatha ekamelweni lekhompyutha.
Isimiso Sokudlulisa
Thatha i-QSFP+AOC njengesibonelo, iziphetho ezimbili zekhebula (A ekupheleni no-B end) zingamadivayisi emojula ye-QSFP optical ngokulandelana.Ekugcineni, okokufaka kwedatha i-Din iyisiginali kagesi.Isignali kagesi iguqulwa ibe isignali ye-optical ye-wavelength ethile nge-EO Converter, futhi isignali ye-optical ifakwa kukhebula le-optical ngemva kokuguqulwa nokuhlanganisa;Ngemva kokuba isignali ye-optical ifinyelele ekupheleni kuka-B ngekhebula le-optical, isignali ye-optical itholwa umtshina optical (OE Converter) futhi ikhuliswe, futhi isignali kagesi ehambisanayo ikhishwa yi-Dout.Isiphetho esingu-B nesiphetho A sidlulisa ngokulinganayo.
