Ngaphezulu kwe-120Tbit/s! I-Telecom, i-ZTE kunye ne-Changfei ngokudibeneyo basete irekhodi elitsha lehlabathi lesantya sothumelo lwexesha lokwenyani le-fiber ebonakalayo enemowudi enye.

Kutshanje, iChina Academy of Telecommunication Research, kunye neZTE Corporation Limited kunye neChangfei Optical Fiber kunye neCable Co., LTD. (emva koku kubhekiselwa kuyo “njengeNkampani yeChangfei”) esekwe kwifayibha yequartz eqhelekileyo yemowudi enye, egqityiweyo iS+C+L yovavanyo lothumelo lomthamo omkhulu weqela elikhulu, elona xesha lokwenyani lomyinge wamaza amaza afikelela kwi-1.2Tbit/s, kwaye umyinge wothumelo lwendlela enyeifayibhaigqithe kwi-120Tbit/s. Misela irekhodi elitsha lehlabathi kwireyithi yokuhanjiswa kwexesha lokwenyani lefiber eqhelekileyo yemowudi enye, elingana nokuxhasa ukuhanjiswa kwamakhulu emiboniso bhanyabhanya enenkcazo ephezulu ye-4K okanye idatha yoqeqesho oluninzi lwemodeli ye-AI ngomzuzwana.

Ngokweengxelo, uvavanyo lokuqinisekisa lwe-fiber eyodwa-unidirectional super 120Tbit/s lufumene iziphumo ezigqwesileyo kububanzi bobubanzi benkqubo, ii-algorithms eziphambili kunye noyilo lwezakhiwo.

Ngokubhekiselele kububanzi benkqubo yobubanzi, ngokusekwe kwi-C-band yemveli, ububanzi bobubanzi benkqubo bukwandiswa ngakumbi ukuya kwi-S kunye ne-L bands ukufezekisa i-bandwidth enkulu yonxibelelwano ye-S + C + L ye-multi-band ukuya kwi-17THz, kwaye Uluhlu lwebhendi lugubungela i-1483nm-1627nm.

Ngokubhekiselele kwii-algorithms eziphambili, i-China Academy of Telecommunication Research idibanisa iimpawu ze-S / C / L ezintathu ze-fiber optical ilahleko kunye nokudluliselwa kwamandla, kwaye iphakamisa isikimu sokwandisa ukusebenza kakuhle kwe-spectrum ngokuhambelana nokulungelelaniswa kwereyithi yesimboli, isithuba sesiteshi kunye nokumodareyitha. uhlobo lwekhowudi. Ngelo xesha, ngoncedo lwe-ZTE ye-multi-band system yokuzalisa i-wave kunye ne-teknoloji yokulinganisa amandla ngokuzenzekelayo, ukusebenza kwenkonzo ye-channel-level ilungelelaniswa kwaye umgama wokuhambisa unyuswa.

Ngokubhekiselele kuyilo lwezakhiwo, ukuhanjiswa kwexesha lokwenyani kwamkela iteknoloji yokutywinwa kwefoto yombane ephucukileyo, inqanaba lebhaud yesignali ye-single-wave idlula i-130GBd, i-bit rate ifikelela kwi-1.2Tbit / s, kwaye inani lamacandelo ombane ligcinwa kakhulu.

Uvavanyo lwamkela i-ultra-low attenuation kunye ne-fiber ebonakalayo yendawo enkulu ephuhliswe yiNkampani ye-Changfei, ene-coefficient esezantsi yokuthomalalisa kunye nendawo enkulu esebenzayo, inceda ukuqonda ukwandiswa kobubanzi benkqubo kwi-S-band, kunye neyona ndawo iphezulu yokwenyani- ixesha elinye izinga lamaza lifikelela 1.2Tbit/s. Ii-fiber opticaluye waqonda ukwakhiwa kwendawo yoyilo, ukulungiselela, inkqubo, imathiriyeli ekrwada kunye namanye amakhonkco.

Itekhnoloji yobukrelekrele bokwenziwa kunye nosetyenziso lwayo lweshishini luyakhula, luzisa ugqabhuko-dubulo kwimfuno ye-data center interconnection bandwidth. Njengoko isiseko sekona ye-bandwidth yeziseko zolwazi lwedijithali, inethiwekhi ye-optical yonke kufuneka iqhube ngakumbi kwireyithi kunye nomthamo wokuhanjiswa kwe-optical. Ukuthobela uthumo "lonxibelelwano oluhlakaniphile lobomi obungcono", inkampani iya kujoyina izandla nabaqhubi kunye nabathengi ukuba bagxile kuphando kunye nophuhliso lwetekhnoloji ephambili yonxibelelwano lwe-optical, ukwenza intsebenziswano enzulu kunye nokuhlola urhwebo kwimimandla. yamaxabiso amatsha, iibhendi ezintsha, kunye nemicu emitsha yamehlo, kunye nokwakha umgangatho omtsha wemveliso yamashishini anezinto ezintsha zobuchwepheshe, ikhuthaza rhoqo uphuhliso oluzinzileyo lwenethiwekhi yonke ye-optical, kunye nokunceda ukwakha isiseko esiluqilima sekamva ledijithali.
