Amagama angukhiye: ukwanda komthamo wenethiwekhi ye-optical, ukusungula izinto ezintsha kwezobuchwepheshe okuqhubekayo, amaphrojekthi okuhlola isikhombikubona esisheshayo aqaliswa kancane kancane
Esikhathini samandla okusebenzisa amakhompyutha, ngentshiseko enamandla yezinsizakalo eziningi ezintsha kanye nezinhlelo zokusebenza, ubuchwepheshe bokuthuthukisa amandla obunezilinganiso eziningi njengesilinganiso sesignali, ububanzi be-spectral obutholakalayo, imodi ye-multiplexing, kanye nemidiya yokudlulisa emisha kuyaqhubeka nokusungula izinto ezintsha nokuthuthukisa.
Okokuqala, ngokombono wokwanda kwesilinganiso sesibonisi noma sesignali yesiteshi, isilinganisoI-PON engu-10GUkufakwa kwenethiwekhi yokufinyelela kunwetshiwe kakhulu, amazinga obuchwepheshe e-50G PON ngokuvamile azinzile, futhi umncintiswano wezixazululo zobuchwepheshe ze-100G/200G PON ukhulu kakhulu; inethiwekhi yokudlulisa ilawulwa yi-100G/200G speed Expansion, isilinganiso sezinga lokuxhumana langaphakathi noma langaphandle lesikhungo sedatha se-400G kulindeleke ukuthi sikhuphuke kakhulu, kuyilapho i-800G/1.2T/1.6T kanye nokunye ukuthuthukiswa komkhiqizo okunezinga eliphezulu kanye nocwaningo olujwayelekile lobuchwepheshe kukhuthazwa ngokubambisana, futhi abakhiqizi abaningi bekhanda lokuxhumana kwe-optical bakwamanye amazwe kulindeleke ukuthi bakhiphe imikhiqizo ye-chip ehlanganisiwe ye-DSP engu-1.2T noma ngaphezulu noma izinhlelo zokuthuthukiswa komphakathi.
Okwesibili, ngokombono we-spectrum etholakalayo yokudlulisa, ukwanda kancane kancane kwe-C-band yezentengiselwano kuya ku-C+L band sekuyindlela yokuhlangana embonini. Kulindeleke ukuthi ukusebenza kokudlulisa kwelabhorethri kuzoqhubeka nokuthuthuka kulo nyaka, futhi ngesikhathi esifanayo kuqhubeke nokwenza ucwaningo kuma-spectrum abanzi njenge-S+C+L band.
Okwesithathu, ngokombono we-signal multiplexing, ubuchwepheshe be-space division multiplexing buzosetshenziswa njengesixazululo sesikhathi eside senkinga yomthamo wokudlulisa. Uhlelo lwekhebula lomkhumbi-ngwenya olusekelwe ekukhuliseni kancane kancane inani lama-optical fiber pairs luzoqhubeka lusetshenziswa futhi lunwetshwe. Ngokusekelwe ku-mode multiplexing kanye/noma multiple Ubuchwepheshe be-core multiplexing buzoqhubeka nokufundwa ngokujulile, kugxilwe ekwandiseni ibanga lokudlulisa kanye nokuthuthukisa ukusebenza kokudlulisa.
Ngemuva kwalokho, ngokombono wemidiya emisha yokudlulisa, i-G.654E ultra-low-loss optical fiber izoba ukukhetha kokuqala kwenethiwekhi ye-trunk futhi iqinise ukuthunyelwa, futhi izoqhubeka nokufunda i-multiplexing optical fiber (ikhebula) yokuhlukanisa isikhala. I-Spectrum, ukubambezeleka okuphansi, umphumela ophansi ongewona owe-linear, ukusabalala okuphansi, nezinye izinzuzo eziningi ziye zaba yinto ebalulekile embonini, kuyilapho ukulahleka kokudluliselwa kanye nenqubo yokudweba kuye kwathuthukiswa kakhulu. Ngaphezu kwalokho, ngokombono wobuchwepheshe kanye nokuqinisekiswa kokuvuthwa komkhiqizo, ukunakwa kokuthuthukiswa kwemboni, njll., opharetha basekhaya kulindeleke ukuthi baqalise amanethiwekhi abukhoma ezinhlelo zesivinini esiphezulu njenge-DP-QPSK 400G ukusebenza ibanga elide, ukuhlala ndawonye kwemodi ephindwe kabili ye-50G PON kanye namakhono okudlulisa alinganayo ngo-2023 Umsebenzi wokuqinisekisa ukuhlolwa uqinisekisa ukuvuthwa kwemikhiqizo ejwayelekile ye-interface yesivinini esiphezulu futhi ubeka isisekelo sokuthunyelwa kwezentengiselwano.
Okokugcina, ngokuthuthukiswa kwesilinganiso sokuxhumana kwedatha kanye nomthamo wokushintsha, ukuhlanganiswa okuphezulu kanye nokusetshenziswa kwamandla okuphansi kube yizidingo zokuthuthukiswa kwemojuli ye-optical yeyunithi eyisisekelo yokuxhumana kwe-optical, ikakhulukazi ezimweni ezijwayelekile zokusetshenziswa kwesikhungo sedatha, lapho umthamo wokushintsha ufinyelela ku-51.2Tbit/s. Ngaphezu kwalokho, uhlobo oluhlanganisiwe lwamamojula we-optical anesilinganiso esingu-800Gbit/s nangaphezulu angase abhekane nomncintiswano wokuhlalisana wephakheji ye-pluggable kanye ne-photoelectric (CPO). Kulindeleke ukuthi izinkampani ezifana ne-Intel, i-Broadcom, ne-Ranovus zizoqhubeka nokuvuselela kulo nyaka. Ngaphezu kwemikhiqizo nezixazululo ze-CPO ezikhona, futhi zingase ziqalise amamodeli emikhiqizo emisha, ezinye izinkampani zobuchwepheshe be-silicon photonics nazo zizolandela ngenkuthalo ucwaningo nentuthuko noma ziyinake kakhulu.
Ngaphezu kwalokho, maqondana nobuchwepheshe bokuhlanganiswa kwe-photonic obusekelwe kuzinhlelo zokusebenza ze-optical module, i-silicon photonics izohambisana nobuchwepheshe bokuhlanganiswa kwe-III-V semiconductor, njengoba ubuchwepheshe be-silicon photonics bunokuhlanganiswa okuphezulu, isivinini esikhulu, kanye nokuhambisana okuhle nezinqubo ze-CMOS ezikhona. I-Silicon photonics isetshenziswe kancane kancane kumamojula we-optical axhumeka ibanga eliphakathi nelifushane, futhi isibe yisisombululo sokuqala sokuhlola sokuhlanganiswa kwe-CPO. Imboni inethemba ngentuthuko yesikhathi esizayo yobuchwepheshe be-silicon photonics, futhi ukuhlola kwayo ukusetshenziswa kuma-optical computing nakwamanye amasimu nakho kuzovumelaniswa.
