Amagama angukhiye: ukwanda komthamo wenethiwekhi ye-optical, ukusungulwa okusha kwezobuchwepheshe okuqhubekayo, amaphrojekthi okuhlola okusebenza ngesivinini esikhulu ethulwa kancane kancane
Esikhathini samandla wekhompiyutha, ngokushayela okuqinile kwezinsizakalo eziningi ezintsha nezinhlelo zokusebenza, ubuchwepheshe bokuthuthukiswa kwamandla amaningi-dimensional obufana nezinga lesignali, ububanzi obutholakalayo be-spectral, imodi yokuphindaphinda, kanye nemidiya emisha yokudlulisela iyaqhubeka nokusungula nokuthuthukisa.
Okokuqala, ngokombono wesixhumi esibonakalayo noma ukukhuphuka kwezinga lesignali yesiteshi, isikali seI-10G PONukuthunyelwa kunethiwekhi yokufinyelela kuye kwanwetshwa ngokuqhubekayo, izindinganiso zobuchwepheshe ze-50G PON ngokuvamile zizinzile, futhi ukuncintisana kwezixazululo zobuchwepheshe ze-100G/200G PON kushubile;inethiwekhi yokudlulisela ilawulwa yi-100G/200G Ukwandiswa kwesivinini, ingxenye yesikhungo sedatha ye-400G izinga lokuxhuma ngaphakathi noma langaphandle kulindeleke ukuthi likhule kakhulu, kuyilapho i-800G/1.2T/1.6T kanye nezinye izinga eliphezulu lokuthuthukiswa komkhiqizo kanye nocwaningo olujwayelekile lwezobuchwepheshe lukhuthazwa ngokuhlanganyela. , kanye nabakhiqizi abaningi bekhanda lokuxhumana okubonakalayo bangaphandle kulindeleke ukuthi bakhulule i-1.2T noma isilinganiso esiphezulu esihambisanayo semikhiqizo ye-chip yokucubungula i-DSP noma izinhlelo zokuthuthukisa umphakathi.
Okwesibili, ngokombono we-spectrum etholakalayo yokudlulisela, ukunwetshwa kancane kancane kwe-C-band yezohwebo kubhendi ye-C+L sekuyisixazululo sokuhlangana embonini.Kulindeleke ukuthi ukusebenza kokudluliselwa kwelabhorethri kuqhubeke nokuba ngcono kulo nyaka, futhi ngesikhathi esifanayo kuqhubeke nokwenza ucwaningo nge-spectrum ebanzi njengebhendi ye-S+C+L.
Okwesithathu, ngokombono we-multiplexing yesignali, ubuchwepheshe be-multiplexing ye-space division buzosetshenziswa njengesixazululo sesikhathi eside ebhodleleni lomthamo wokudlulisa.Isistimu yezintambo ezihamba ngaphansi kwamanzi esekelwe ekwandiseni kancane kancane inani lamapheya e-optical fibre izoqhubeka nokusetshenziswa futhi yandiswe.Ngokusekelwe kumodi yokuphindaphinda kanye/noma eminingi Ubuchwepheshe bokuphindaphinda okuyisisekelo buzoqhubeka nokufundwa ngokujulile, kugxile ekwandiseni ibanga lokudlulisela kanye nokwenza ngcono ukusebenza kokudlulisela.
Khona-ke, ngokombono wemidiya entsha yokudlulisela, i-G.654E i-ultra-low-loss optical fiber izoba yinketho yokuqala yenethiwekhi ye-trunk futhi iqinise ukuthunyelwa, futhi izoqhubeka nokutadisha i-space-division multiplexing optical fiber (ikhebula).I-Spectrum, ukubambezeleka okuphansi, umphumela ophansi ongaqondile, ukuhlakazeka okuphansi, nezinye izinzuzo eziningi sekugxilwe kakhulu embonini, kuyilapho ukulahlekelwa kokudlulisela kanye nenqubo yokudweba kuye kwathuthukiswa nakakhulu.Ukwengeza, ngokombono wobuchwepheshe nokuqinisekiswa kokuvuthwa komkhiqizo, ukunakwa kokuthuthukiswa kwezimboni, njll., opharetha basekhaya kulindeleke ukuthi baqalise amanethiwekhi abukhoma wezinhlelo zejubane eliphezulu njenge-DP-QPSK 400G ukusebenza kwebanga elide, ukuhlalisana kwe-50G PON kabili kwemodi kanye nekhono lokudlulisela elilinganayo ngo-2023 Umsebenzi wokuqinisekisa ukuhlolwa uqinisekisa ukuvuthwa kwemikhiqizo evamile yesivinini esiphezulu futhi ubeka isisekelo sokuthunyelwa kwezentengiso.
Okokugcina, ngokuthuthukiswa kwezinga lokusetshenziswa kwedatha kanye nomthamo wokushintsha, ukuhlanganiswa okuphezulu kanye nokusetshenziswa kwamandla okuphansi kuye kwaba yizidingo zokuthuthukiswa kwemojula ye-optical yeyunithi eyisisekelo yokuxhumana optical, ikakhulukazi ezimweni ezijwayelekile zohlelo lokusebenza lwesikhungo sedatha, lapho umthamo wokushintsha ufinyelela ku-51.2 I-Tbit/s Futhi ngenhla, ifomu elihlanganisiwe lamamojula optical anesilinganiso esingu-800Gbit/s nangaphezulu angase abhekane nokuncintisana kokuhlalisana kwephakeji ye-plugable kanye ne-photoelectric (CPO).Kulindeleke ukuthi izinkampani ezifana ne-Intel, i-Broadcom, ne-Ranovus zizoqhubeka nokuvuselela phakathi nalo nyaka Ngaphezu kwemikhiqizo ekhona ye-CPO nezisombululo, futhi zingase zethule amamodeli emikhiqizo emisha, ezinye izinkampani zobuchwepheshe be-silicon photonics nazo zizolandela ngenkuthalo ucwaningo nentuthuko. noma uyinakisise.
Ngaphezu kwalokho, mayelana nobuchwepheshe bokuhlanganiswa kwe-photonic obusekelwe ekusetshenzisweni kwe-optical module, i-silicon photonics izosebenzisana nobuchwepheshe bokuhlanganiswa kwe-semiconductor III-V, njengoba ubuchwepheshe be-silicon photonics bunokuhlanganiswa okuphezulu, isivinini esikhulu, nokuhambisana okuhle nezinqubo ezikhona ze-CMOS I-Silicon photonics iye yasungulwa. kancane kancane isetshenziswa kumamojula optical axhumeke amabanga aphakathi nafushane, futhi isibe yisixazululo sokuqala sokuhlola sokuhlanganiswa kwe-CPO.Imboni inethemba ngentuthuko yesikhathi esizayo yobuchwepheshe be-silicon photonics, futhi ukuhlolwa kokusetshenziswa kwayo kukhompyutha yamehlo neminye imikhakha nakho kuzovumelaniswa kwenziwe.
