Ngaphezulu kwe-120Tbit/s! I-Telecom, i-ZTE kunye ne-Changfei zibeke irekhodi elitsha lehlabathi ngesantya sokusasazwa kwe-fiber optical eqhelekileyo ye-single-mode

Kutshanje, i-China Academy of Telecommunication Research, kunye ne-ZTE Corporation Limited kunye ne-Changfei Optical Fiber and Cable Co., LTD. (ebizwa ngokuba yi-"Changfei Company") ngokusekelwe kwi-single-mode single-mode quartz fiber, igqibe uvavanyo lokudlulisa amandla amakhulu lwe-S+C+L multi-band, isantya esiphezulu se-single-wave esifike kwi-1.2Tbit/s, kunye nesantya sokudlulisa esibhekisele kwicala elinye se-single-direction.ifayibhaidlule kwi-120Tbit/s. Beka irekhodi elitsha lehlabathi lesantya sokudluliselwa kwe-fiber eqhelekileyo yemowudi enye ngexesha langempela, elilingana nokuxhasa ukuhanjiswa kwamakhulu eemuvi ze-4K eziphezulu okanye idatha yoqeqesho lweemodeli ze-AI ezininzi ngomzuzwana.

Ngokweengxelo, uvavanyo lokuqinisekisa lwe-single-fiber unidirectional super 120Tbit/s lufumene iziphumo eziphambili kububanzi be-system spectrum, ii-key algorithms kunye noyilo lwezakhiwo.

Ngokuphathelele ububanzi be-spectrum yenkqubo, ngokusekelwe kwi-C-band yendabuko, ububanzi be-spectrum yenkqubo lulwandiselwa ngakumbi kwiibhendi ze-S kunye ne-L ukuze kufezekiswe i-bandwidth yonxibelelwano enkulu kakhulu ye-S+C+L multi-band ukuya kuthi ga kwi-17THz, kwaye uluhlu lwebhendi lugubungela i-1483nm-1627nm.

Ngokuphathelele ii-algorithms eziphambili, i-China Academy of Telecommunication Research idibanisa iimpawu zokulahleka kwe-S/C/L three-band optical fiber kunye nokudluliselwa kwamandla, kwaye icebisa isicwangciso sokwandisa ukusebenza kakuhle kwe-spectrum ngokuhambelana okuguquguqukayo kwesantya sesimboli, isithuba setshaneli kunye nohlobo lwekhowudi yokuguqula. Kwangaxeshanye, ngoncedo lwe-ZTE's multi-band filling wave kunye netekhnoloji yokulinganisela amandla ngokuzenzekelayo, ukusebenza kwenkonzo yenqanaba letshaneli kuyalingana kwaye umgama wokudlulisela uyanda.

Ngokuphathelele uyilo lwezakhiwo, uthumelo lwexesha langempela lusebenzisa ubuchwepheshe bokutywina be-photoelectric obuphambili kushishino, izinga le-baud yesignali ye-single-wave lidlula i-130GBd, izinga le-bit lifikelela kwi-1.2Tbit/s, kwaye inani lezinto ze-photoelectric ligcinwa kakhulu.

Olu vavanyo lusebenzisa i-ultra-low attenuation kunye ne-large effective area fiber optical fibre eyenziwe yiChangfei Company, ene-attenuation coefficient ephantsi kunye ne-large effective area, enceda ekufezekiseni ulwandiso lobubanzi be-spectral yenkqubo kwi-S-band, kwaye i-single wave rate ephezulu ye-real-time ifikelela kwi-1.2Tbit/s.ifayibha ye-opticaliqaphele ukwakheka kwendawo yoyilo, ukulungiswa, inkqubo, izinto ezikrwada kunye nezinye iikhonkco.

Itekhnoloji yobukrelekrele bokwenziwa kunye nezicelo zayo zoshishino ziyakhula, nto leyo ebangela ukwanda kwemfuno ye-bandwidth yokunxibelelana kweziko ledatha. Njengesiseko se-bandwidth yeziseko zolwazi zedijithali, inethiwekhi ye-all-optical kufuneka idlule kwinqanaba kunye nomthamo wokudluliselwa kwe-optical. Ngokunamathela kwinjongo "yonxibelelwano olukrelekrele lobomi obungcono", inkampani iya kudibana nabaqhubi kunye nabathengi ukugxila kuphando kunye nophuhliso lwetekhnoloji eziphambili zonxibelelwano lwe-optical, ukwenza intsebenziswano enzulu kunye nophando lwezorhwebo kwicandelo lamaxabiso amatsha, iibhendi ezintsha, kunye neefayibha ezintsha ze-optical, kunye nokwakha imveliso entsha esemgangathweni yamashishini ane-teknoloji entsha, ukukhuthaza rhoqo uphuhliso oluzinzileyo lwenethiwekhi ye-all-optical, kunye nokunceda ukwakha isiseko esiqinileyo sekamva ledijithali.
