Amagama angundoqo: Ukwanda komthamo womnatha wokubona, ukwenziwa kwezinto ezintsha kwetekhnoloji, iiprojekthi zokulinga ujongano olunesantya esiphezulu ngokuthe ngcembe zasungulwa.
Ngexesha lamandla e-computing, kunye ne-drive eqinile yeenkonzo ezininzi ezintsha kunye nezicelo, i-multi-dimensional umthamo wokuphucula ubuchwepheshe obufana nesantya sesignali, ububanzi obukhoyo be-spectral, i-multiplexing mode, kunye neendaba zokusasaza ezintsha ziyaqhubeka nokuvuselela nokuphuhlisa.
Okokuqala, ngokombono we-interface okanye ishaneli yokwandisa izinga lomqondiso, umlinganiselo we10G PONukuthunyelwa kwinethiwekhi yokufikelela kuye kwandiswa ngakumbi, imigangatho yobugcisa ye-50G PON iye yazinza ngokubanzi, kwaye ukhuphiswano lwe-100G / 200G izisombululo ze-PON zobugcisa zibukhali;inethiwekhi yothumelo ilawulwa yi-100G / 200G Ukwandiswa kwesantya, umlinganiselo we-400G yedatha yedatha yangaphakathi okanye yangaphandle izinga lokudibanisa lilindeleke ukuba linyuke kakhulu, ngelixa i-800G / 1.2T / 1.6T kunye nezinye izinga eliphezulu lophuhliso lwemveliso kunye nophando olusemgangathweni lwezobugcisa lukhuthazwa ngokubambisana. , kunye nabavelisi bentloko yonxibelelwano lwangaphandle kulindeleke ukuba bakhulule i-1.2T okanye izinga eliphezulu elihambelana nemveliso ye-chip ye-DSP okanye izicwangciso zophuhliso loluntu.
Okwesibini, ukusuka kumbono we-spectrum ekhoyo yokuhanjiswa, ukwandiswa ngokuthe ngcembe kwe-C-band yorhwebo kwi-C + L band ibe sisisombululo sokudibanisa kwishishini.Kulindeleke ukuba umsebenzi wokuhanjiswa kwebhubhoratri uya kuqhubeka uphucula kulo nyaka, kwaye kwangaxeshanye uqhubeke nokuqhuba uphando kwiimpawu ezibanzi ezifana nebhendi ye-S + C + L.
Okwesithathu, kumbono we-multiplexing yesignali, iteknoloji ye-multiplexing yokwahlula indawo iya kusetyenziswa njengesisombululo sexesha elide kwi-bottleneck yomthamo wokuhambisa.Inkqubo yentambo yangaphantsi kwamanzi esekelwe ekwandiseni ngokuthe chu inani leeperi zefiber optical iya kuqhubeka ukuthunyelwa kunye nokwandiswa.Ngokusekelwe kwimodi yokuphindaphinda kunye / okanye ukuphindaphinda I-teknoloji ye-core multiplexing iya kuqhubeka ifundwa ngokunzulu, igxininise ekunyuseni umgama wokuhambisa kunye nokuphucula ukusebenza kokuhanjiswa.
Emva koko, ngokombono weendaba ezintsha zothumelo, i-G.654E i-ultra-low-loss optical fiber iya kuba yinto yokuqala yokukhetha kwinethiwekhi ye-trunk kunye nokuqinisa ukuthunyelwa, kwaye iya kuqhubeka ifundela i-space-division multiplexing fiber optical (ikhebula).I-Spectrum, ukulibaziseka okuphantsi, umphumo ophantsi ongekho ngaphantsi, ukusabalalisa okuphantsi, kunye nezinye iingenelo ezininzi ziye zaba yingqwalasela yoshishino, ngelixa ukulahleka kokuhanjiswa kunye nenkqubo yokudweba iye yaphuculwa ngakumbi.Ukongezelela, kumbono wethekhnoloji kunye nokuqinisekiswa kokuvuthwa kwemveliso, ingqalelo yophuhliso lweshishini, njl., Abaqhubi basekhaya kulindeleke ukuba baqalise amanethiwekhi aphilayo e-high-speed systems ezifana ne-DP-QPSK 400G ukusebenza okude, i-50G PON-mode-mode coexistence. kunye nesakhono sothumelo olulingeneyo ngo-2023 Umsebenzi wokuqinisekisa uvavanyo ngakumbi uqinisekisa ukukhula kweemveliso zojongano olukwisantya esiphezulu kwaye ubeka isiseko sokusasazwa kwezorhwebo.
Ekugqibeleni, kunye nokuphuculwa kwesantya sokujonga idatha kunye nokutshintsha amandla, ukuhlanganiswa okuphezulu kunye nokusetyenziswa kwamandla aphantsi kuye kwaba yimfuno yophuhliso lwemodyuli ye-optical yeyunithi esisiseko yonxibelelwano lwe-optical, ngokukodwa kwiimeko eziqhelekileyo zokusetyenziswa kweziko ledatha, xa amandla okutshintsha afikelela kwi-51.2. I-Tbit / s Kwaye ngasentla, ifom edibeneyo yeemodyuli ze-optical kunye nesantya se-800Gbit / s nangaphezulu inokujongana nokhuphiswano lokuhlalisana kwe-pluggable kunye ne-photoelectric package (CPO).Kulindeleke ukuba iinkampani ezifana ne-Intel, i-Broadcom, kunye ne-Ranovus ziya kuqhubeka zihlaziywa kulo nyaka Ukongeza kwiimveliso ze-CPO ezikhoyo kunye nezisombululo, kwaye zinokusungula imodeli yemveliso emitsha, ezinye iinkampani zeteknoloji ze-silicon photonics nazo ziyakulandela ngenkuthalo uphando kunye nophuhliso. okanye unikele ingqalelo kuyo.
Ukongeza, ngokwetekhnoloji yokudibanisa ifotoni esekwe kwizicelo zemodyuli ye-optical, i-silicon photonics iya kuhlala kunye ne-III-V yetekhnoloji yokudityaniswa kwe-semiconductor, inikwe ukuba itekhnoloji ye-silicon photonics inodibaniso oluphezulu, isantya esiphezulu, kunye nokuhambelana kakuhle neenkqubo ezikhoyo ze-CMOS I-Silicon photonics sele yenziwe. isetyenziswe ngokuthe ngcembe kwiimodyuli ze-optical pluggable eziphakathi kunye nezifutshane, kwaye ibe sisisombululo sokuqala sokuhlola ukuhlanganiswa kweCPO.Ishishini linethemba malunga nophuhliso lwexesha elizayo lwetekhnoloji ye-silicon photonics, kunye nokuphononongwa kwesicelo sayo kwikhompyuter ye-optical kunye neminye imimandla iya kwenziwa ngaxeshanye.
