Muva nje, i-China Academy of Telecommunication Research, kanye ne-ZTE Corporation Limited kanye ne-Changfei Optical Fiber and Cable Co., LTD. (ebizwa ngokuthi “iChangfei Company”) ngokusekelwe ku-fiber ye-quartz evamile yemodi eyodwa, iqedele ukuhlolwa kokudlulisa amandla amakhulu kwe-S+C+L multi-band, izinga eliphezulu kakhulu le-single-wave ngesikhathi sangempela lifinyelele ku-1.2Tbit/s, kanye nezinga lokudlulisa eliqondiswe ngqo le-single-direction.ifayibhakudlule i-120Tbit/s. Setha irekhodi elisha lomhlaba lesilinganiso sokudlulisa sangempela sefayibha evamile yemodi eyodwa, okulingana nokusekela ukudluliselwa kwamakhulu ama-movie anencazelo ephezulu ye-4K noma idatha yokuqeqeshwa kwemodeli ye-AI eminingana ngomzuzwana.
Ngokusho kwemibiko, ukuhlolwa kokuqinisekisa kwe-single-fiber unidirectional super 120Tbit/s kufinyelele imiphumela ephumelelayo ebubanzini be-spectrum yesistimu, ama-algorithms ayisihluthulelo kanye nomklamo wezakhiwo.
Ngokuphathelene nobubanzi be-spectrum yesistimu, ngokusekelwe ku-C-band yendabuko, ububanzi be-spectrum yesistimu bunwetshwa ngokwengeziwe kuma-S kanye nama-L band ukuze kufezwe i-bandwidth yokuxhumana enkulu kakhulu ye-S+C+L multi-band efika ku-17THz, futhi ububanzi be-band buhlanganisa i-1483nm-1627nm.
Ngokuphathelene nama-algorithms ayisihluthulelo, i-China Academy of Telecommunication Research ihlanganisa izici zokulahlekelwa yi-S/C/L three-band optical fiber kanye nokudluliswa kwamandla, futhi iphakamisa uhlelo lokukhulisa ukusebenza kahle kwe-spectrum ngokufanisa okuguquguqukayo kwesilinganiso sezimpawu, isikhawu sesiteshi kanye nohlobo lwekhodi yokushintshashintsha. Ngesikhathi esifanayo, ngosizo lwe-ZTE's multi-band system filling wave kanye nobuchwepheshe bokulinganisa amandla okuzenzakalelayo, ukusebenza kwesevisi yezinga lesiteshi kuyalinganiswa futhi ibanga lokudlulisela liyakhuliswa.
Ngokuphathelene nomklamo wezakhiwo, ukudluliswa kwesikhathi sangempela kusebenzisa ubuchwepheshe bokuvala i-photoelectric obuthuthukisiwe embonini, izinga le-baud yesignali ye-single-wave lidlula i-130GBd, izinga le-bit lifinyelela ku-1.2Tbit/s, futhi inani lezingxenye ze-photoelectric lilondolozwa kakhulu.
Lolu cwaningo lusebenzisa i-ultra-low attenuation kanye ne-large effective area optical fiber eyakhiwe yi-Changfei Company, ene-attenuation coefficient ephansi kanye nendawo ephumelelayo enkulu, okusiza ekufezeni ukwanda kobubanzi be-spectral yesistimu ku-S-band, kanye ne-real-time single wave rate ephezulu kakhulu ifinyelela ku-1.2Tbit/s.i-fiber ebonakalayoikwazile ukwakheka kwendawo, ukulungiselela, inqubo, izinto zokusetshenziswa kanye nezinye izixhumanisi.
Ubuchwepheshe bobuhlakani bokwenziwa kanye nezinhlelo zokusebenza zebhizinisi labo ziyachuma, okuletha ukuqhuma kwesidingo se-bandwidth yokuxhumana kwesikhungo sedatha. Njengesisekelo se-bandwidth yengqalasizinda yolwazi lwedijithali, inethiwekhi ye-all-optical idinga ukuqhubeka nokudlula izinga kanye namandla okudluliselwa kwe-optical. Inamathela emgomweni "wokuxhumana okuhlakaniphile ukuze kube nempilo engcono", inkampani izosebenzisana nabasebenzi namakhasimende ukugxila ocwaningweni nasekuthuthukisweni kobuchwepheshe obuyinhloko bokuxhumana kwe-optical, yenze ukubambisana okujulile kanye nokuhlola kwezentengiselwano emikhakheni yamanani amasha, amabhande amasha, kanye nemicu emisha ye-optical, futhi yakhe umkhiqizo omusha wekhwalithi wamabhizinisi anokusungula ubuchwepheshe, ikhuthaze njalo intuthuko esimeme yenethiwekhi ye-all-optical, futhi isize ekwakheni isisekelo esiqinile sekusasa ledijithali.
