Ukuqulunqwa kweizixhobo zonxibelelwano zamehlo
Inkqubo yonxibelelwano kunye namaza okukhanya njengomqondiso kunye ne-Optical fiber njengoko i-transmission medium ibizwa ngokuba yi-Optical fiber communication system. Izinto eziluncedo zonxibelelwano lwefiber optical xa kuthelekiswa nonxibelelwano lwentambo yemveli kunye nonxibelelwano olungenazingcingo zezi: umthamo omkhulu wonxibelelwano, ilahleko ephantsi yothumelo, isakhono esinamandla sokuphazamiseka kombane, imfihlo eyomeleleyo, kunye nesixhobo sokuhambisa i-fiber optical yisilicon dioxide enokugcinwa okuninzi. Ukongeza, i-fiber optical inezibonelelo zobukhulu obuncinci, ubunzima obulula kunye neendleko eziphantsi xa kuthelekiswa nentambo.
Lo mzobo ulandelayo ubonisa amacandelo esekethe edibeneyo yefotonic:laser, ukusetyenziswa kwakhona kwamehlo kunye nesixhobo sokwenza izinto ezininzi,ifotodetectorkwayeimodyuli.
Isakhiwo esisisiseko se-fiber optical fibre bidirectional communication system ibandakanya: i-transmitter yombane, i-optical transmitter, i-fiber yokudlulisa, i-optical receiver kunye ne-receiver yombane.
Isibonakaliso sombane esinesantya esiphezulu sifakwe ngekhowudi yi-transmitter yombane kwi-transmitter ye-optical transmitter, iguqulelwe kwiimpawu ezibonakalayo ngezixhobo ze-electro-optical ezifana ne-Laser device (LD), kwaye emva koko idityaniswe kwifayibha yokuhambisa.
Emva kokuhanjiswa komgama omde wesiginali ye-optical ngokusebenzisa i-fiber yemowudi enye, i-erbium-doped fiber amplifier ingasetyenziselwa ukukhulisa umqondiso kunye nokuqhubeka nokuhanjiswa. Emva kokuphela kokufumana i-optical, umqondiso we-optical uguqulwa ube ngumqondiso wombane nge-PD kunye nezinye izixhobo, kwaye umqondiso ufunyenwe ngummkeli wombane ngokusebenzisa umbane olandelayo. Inkqubo yokuthumela nokufumana imiqondiso kwicala elichaseneyo iyafana.
Ukuze ufezekise ukulungelelaniswa kwezixhobo kwikhonkco, i-transmitter optical kunye ne-optical receiver kwindawo efanayo ihlanganiswe ngokuthe ngcembe kwi-Transceiver optical.
Isantya esiphezuluImodyuli ye-Optical transceiveryenziwe yiReceiver Optical Subassembly (ROSA; Transmitter Optical Subassembly (TOSA) emelwe zizixhobo zamehlo ezisebenzayo, izixhobo ze-passive, iisekethe ezisebenzayo kunye ne-photoelectric interface components ziyapakishwa.I-ROSA kunye ne-TOSA zipakishwe ngee-lasers, i-photodetectors, njl. iitshiphusi zamehlo.
Xa bejongene ne-bottleneck yomzimba kunye nemingeni yobugcisa ekuhlangatyenwe nayo kuphuhliso lwetekhnoloji ye-microelectronics, abantu baqala ukusebenzisa iifoton njengabathwali bolwazi ukufikelela kwi-bandwidth enkulu, isantya esiphezulu, ukusetyenziswa kwamandla aphantsi, kunye nokulibaziseka okuphantsi kwe-photonic inteated circuit (PIC). Injongo ebalulekileyo ye-loop edibeneyo ye-photonic kukuqonda ukuhlanganiswa kwemisebenzi yokuvelisa ukukhanya, ukudibanisa, ukumodareyitha, ukucoca, ukuhanjiswa, ukufumanisa kunye nokunye. Amandla okuqhubela phambili okuqhubela phambili kweesekethe ezidibeneyo ze-photonic zivela kunxibelelwano lwedatha, kwaye emva koko iye yaphuhliswa kakhulu kwi-microwave photonics, i-quantum information processing, i-nonlinear optics, i-sensor, i-lidar kunye nezinye iindawo.
