Amagama angundoqo: ukwanda komthamo wenethiwekhi ye-optical, uphuhliso lwetekhnoloji oluqhubekayo, iiprojekthi zovavanyo lwe-interface yesantya esiphezulu ziqaliswa kancinci kancinci
Kwixesha lamandla ekhompyutha, kunye nogqozi oluqinileyo lweenkonzo ezininzi ezintsha kunye nezicelo, ubuchwepheshe bokuphucula umthamo obunemilinganiselo emininzi obufana nesantya sesignali, ububanzi be-spectral obufumanekayo, imo ye-multiplexing, kunye neendaba ezintsha zokusasaza ziyaqhubeka nokuvelisa izinto ezintsha nophuhliso.
Okokuqala, ngokwembono yokwanda kwesantya sesignali ye-interface okanye yesiteshi, ubungakananiI-PON ye-10GUkusasazwa kwenethiwekhi yokufikelela kuye kwandiswa ngakumbi, imigangatho yobuchwephesha ye-50G PON ngokubanzi izinzile, kwaye ukhuphiswano lwezisombululo zobugcisa ze-100G/200G PON lunamandla; inethiwekhi yothumelo ilawulwa kukwandiswa kwesantya se-100G/200G, umlinganiselo wezinga lokunxibelelana kwangaphakathi okanye kwangaphandle kwe-400G kulindeleke ukuba unyuke kakhulu, ngelixa i-800G/1.2T/1.6T kunye nolunye uphuhliso lwemveliso oluphezulu kunye nophando olusemgangathweni wobugcisa zikhuthazwa ngokudibeneyo, kwaye abavelisi abaninzi beentloko zonxibelelwano lwe-optical bangaphandle kulindeleke ukuba bakhuphe iimveliso ze-chip ze-DSP ezihambelanayo ze-1.2T okanye ezikumgangatho ophezulu okanye izicwangciso zophuhliso loluntu.
Okwesibini, ngokwembono ye-spectrum ekhoyo yokudlulisela, ukwandiswa kancinci kancinci kwe-C-band yorhwebo ukuya kwi-C+L band kube sisisombululo sokudibana kwishishini. Kulindeleke ukuba ukusebenza kokudluliselwa kwelebhu kuya kuqhubeka kuphucuka kulo nyaka, kwaye kwangaxeshanye kuqhubeke nokwenza uphando kwii-spectrum ezibanzi ezifana ne-S+C+L band.
Okwesithathu, ngokwembono ye-signal multiplexing, iteknoloji ye-space division multiplexing iya kusetyenziswa njengesisombululo sexesha elide kwi-bottleneck of transmission capacity. Inkqubo ye-submarine cable esekelwe ekwandiseni kancinci inani lee-optical fiber pairs iya kuqhubeka isetyenziswa kwaye yandiswa. Ngokusekelwe kwi-mode multiplexing kunye/okanye multiple Itekhnoloji ye-core multiplexing iya kuqhubeka ifundwa nzulu, igxile ekwandiseni umgama wokudlulisela kunye nokuphucula ukusebenza kokudlulisela.
Emva koko, ngokwembono yeendaba ezintsha zokusasaza, i-G.654E ultra-low-loss optical fiber iya kuba lukhetho lokuqala lwenethiwekhi yetrunk kwaye yomeleze ukusasazwa, kwaye iya kuqhubeka nokufunda i-multiplexing optical fiber (ikhebula) yokwahlulahlula isithuba. I-Spectrum, ukulibaziseka okuphantsi, isiphumo esiphantsi esingelulo ulayini, ukusasazeka okuphantsi, kunye nezinye izibonelelo ezininzi ziye zaba yinto ephambili kushishino, ngelixa inkqubo yokulahleka kokusasaza kunye nokuzoba iye yaphuculwa ngakumbi. Ukongeza, ngokwembono yetekhnoloji kunye nokuqinisekiswa kokuvuthwa kwemveliso, ingqwalasela yophuhliso lweshishini, njl.njl., abaqhubi basekhaya kulindeleke ukuba baqalise iinethiwekhi ezibukhoma zeenkqubo ezikhawulezayo ezifana nokusebenza komgama omde kwe-DP-QPSK 400G, ukuhlala kunye kwe-50G PON kunye nokukwazi ukuhambisa ngokulinganayo ngo-2023. Umsebenzi wokuqinisekisa uvavanyo uqinisekisa ngakumbi ukuvuthwa kweemveliso eziqhelekileyo zojongano olukhawulezayo kwaye ubeka isiseko sokusasazwa kwezorhwebo.
Okokugqibela, ngokuphuculwa kwesantya sojongano lwedatha kunye nomthamo wokutshintsha, ukuhlanganiswa okuphezulu kunye nokusetyenziswa kwamandla okuphantsi kuye kwaba ziimfuno zophuhliso lwemodyuli ye-optical yeyunithi esisiseko yonxibelelwano lwe-optical, ngakumbi kwiimeko eziqhelekileyo zesicelo seziko ledatha, xa umthamo wokutshintsha ufikelela kwi-51.2Tbit/s Kwaye ngaphezulu, uhlobo oludibeneyo lweemodyuli ze-optical ezinesantya se-800Gbit/s nangaphezulu zinokujongana nokhuphiswano lokuhlala kunye lwephakheji ye-pluggable kunye ne-photoelectric (CPO). Kulindeleke ukuba iinkampani ezifana ne-Intel, i-Broadcom, kunye ne-Ranovus ziya kuqhubeka nokuhlaziya kulo nyaka Ukongeza kwiimveliso kunye nezisombululo ze-CPO ezikhoyo, kwaye zinokuqalisa iimodeli zemveliso ezintsha, ezinye iinkampani zobuchwepheshe be-silicon photonics nazo ziya kulandela uphando kunye nophuhliso okanye zilunike ingqalelo esondeleyo.
Ukongeza, ngokweteknoloji yokudibanisa i-photonic esekwe kwizicelo ze-optical module, i-silicon photonics iya kuhlala kunye neteknoloji yokudibanisa i-III-V semiconductor, njengoko iteknoloji ye-silicon photonics inokudibanisa okuphezulu, isantya esiphezulu, kunye nokuhambelana okuhle neenkqubo ze-CMOS ezikhoyo. I-Silicon photonics iye yasetyenziswa kancinci kancinci kwiimodyuli ze-optical ezixhunywayo eziphakathi nezimfutshane, kwaye iye yaba sisisombululo sokuqala sokuhlola sokudibanisa i-CPO. Eli shishini linethemba malunga nophuhliso lwexesha elizayo lwetekhnoloji ye-silicon photonics, kwaye uphando lwayo lwesicelo kwi-optical computing nakwezinye iindawo nalo luya kuhambelana.
