[Intshayelelo] Itekhnoloji yolwahlulo lwe-wavelength i-multiplexing inokuthi isebenzise ngokupheleleyo izibonelelo ezinkulu ze-bandwidth eziziswa yindawo ephantsi yelahleko yefiber yendlela enye. Ngokwe-frequency (okanye i-wavelength) ye-wave wave ye-channel nganye, yahlula i-window yelahleko ephantsi yefayibha kwiitshaneli ezininzi, sebenzisa i-wave wave njengomphathi wesiginali, kwaye usebenzise i-multiplexer ye-wavelength division multiplexer (multiplexer) isiphelo sothumelo.
Itekhnoloji yolwahlulo lwe-wavelength ephindaphinda itekhnoloji inokusebenzisa ngokupheleleyo izixhobo ezinkulu ze-bandwidth eziziswa ngummandla welahleko ephantsi yefiber yendlela enye. Ngokwe-frequency (okanye ubude be-wavelength) yokukhanya kweshaneli nganye, i-window ephantsi yelahleko ye-fiber optical yahlulahlulwe ibe ngamajelo amaninzi, i-wave wave isetyenziswa njengomphathi wesiginali, kunye ne-multiplexer ye-wavelength division multiplexer. ) isetyenziswa ekupheleni kothumelo. Abathwali be-signal optical of wavelengths badityanisiwe kwaye bathunyelwa kwi-fiber optical yokudluliselwa. Ekupheleni kokufumana, i-wavelength division multiplexer (i-wave splitter) yahlula aba bathwali be-optical baphethe izibonakaliso ezahlukeneyo kubude bamaza ahlukeneyo. Ekubeni izibonakaliso ze-optical carrier ze-wavelengths ezahlukeneyo zingathathwa njengezizimeleyo komnye nomnye (ngaphandle kokuqwalasela ukungahambi kakuhle kwe-fiber optical), ukuphindaphinda kunye nokuhanjiswa kweempawu ezininzi ze-optical kungenziwa kwifiber enye ye-optical.
ITekhnoloji yoFikelelo lweFayibha
Inethiwekhi yokufikelela kwifiber optical "yimayile yokugqibela" yohola wendlela yolwazi. Ukufezekisa ukuhanjiswa kolwazi olukhawulezayo kunye nokuhlangabezana neemfuno zoluntu, kungekuphela nje uthungelwano lwe-broadband backbone transmission, kodwa nenxalenye yokufikelela kumsebenzisi ingundoqo. Inethiwekhi yokufikelela kwifiber ye-Optical yitekhnoloji ephambili yolwazi oluhamba ngesantya esiphezulu ukuya kumawakawaka amakhaya. Kwi-fiber optical fiber broadband access, ngenxa yeendawo ezahlukeneyo zokufika ze-optical fibers, kukho izicelo ezahlukeneyo ezifana ne-FTTB, i-FTTC, i-FTCab kunye ne-FTTH, ngokudibeneyo ebizwa ngokuba yi-FTTx. Ngoko ke, inokusebenzisa ngokupheleleyo iimpawu ze-broadband ze-fiber optical fibers, zibonelela abasebenzisi nge-bandwidth efunekayo engavumelekanga, kwaye ihlangabezane ngokupheleleyo neemfuno zokufikelela kwi-broadband. Okwangoku, iteknoloji yasekhaya inokubonelela abasebenzisi nge-FE okanye i-GE bandwidth, eyona ndlela ifanelekileyo yokufikelela kubasebenzisi bamashishini amakhulu kunye naphakathi.
Uphuhliso lweTekhnoloji yoNxibelelwano lweFayibha ye-Optical
Kwiminyaka yakutshanje, ngokuhambela phambili kwetekhnoloji, uhlaziyo lwenkqubo yolawulo lonxibelelwano kunye nokuvulwa ngokuthe ngcembe kwemarike yonxibelelwano, uphuhliso lonxibelelwano lwefiber optical kwakhona lubonise imeko entsha yophuhliso olunamandla. Oku kulandelayo yintshayelelo emfutshane kwezona ndawo ziphambili zophuhliso kwicandelo lonxibelelwano lwefiber optical. Inkcazo kunye nethemba, ukuphuhliswa kweenkqubo ze-ultra-high-speed, ukuguquka kwiinkqubo ze-WDM ze-ultra-large-capacity.
Xa sijonga kuphuhliso lonxibelelwano lwefiber optical kwiminyaka yakutshanje, ukwakha umqolo wesizwe womnatha optical yeyona nto ingafihliyo, ebhetyebhetye kakhulu kwaye inamandla amakhulu ayinakho nje ukubeka isiseko esiluqilima sexesha elizayo leNational Information Infrastructure (NII), kodwa ngokunjalo noshishino lwelizwe lam lolwazi kwinkulungwane ezayo kunye nokuqhambuka koqoqosho lwesizwe kunye nokhuseleko lwesizwe lubaluleke kakhulu ngokubaluleka kobuchule. Uphuhliso lweshishini lonxibelelwano lwefiber optical lukwayindlela engenakuguqulwa yonxibelelwano lwangoku.
