Ngaphezu kwe-120Tbit/s! I-Telecom, i-ZTE kanye ne-Changfei ngokuhlanganyela babeke irekhodi elisha lomhlaba ngezinga lokudlulisela lesikhathi sangempela le-fiber ebonakalayo yemodi eyodwa

Muva nje, i-China Academy of Telecommunication Research, kanye ne-ZTE Corporation Limited kanye ne-Changfei Optical Fiber ne-Cable Co., LTD. (ngemuva kwalokhu okubizwa ngokuthi “iNkampani ye-Changfei”) ngokusekelwe ku-quartz fiber yemodi eyodwa, okuphothuliwe ukuhlolwa kokudlulisa umthamo omkhulu kwamaqembu amaningi we-S+C+L, izinga eliphakeme kakhulu lesikhathi sangempela le-wave elilodwa lifinyelele ku-1.2Tbit/s, futhi izinga lokudluliswa kokuqondisa okukodwai-fiberkudlule i-120Tbit/s. Setha irekhodi lomhlaba elisha lezinga lokudlulisela lesikhathi sangempela sefayibha yemodi eyodwa evamile, elilingana nokusekela ukudluliswa kwamakhulu amamuvi encazelo ephezulu ye-4K noma idatha yokuqeqeshwa yemodeli ye-AI eminingana ngomzuzwana.

Ngokwemibiko, ukuhlolwa kokuqinisekisa kwe-single-fiber unidirectional super 120Tbit/s kuzuze imiphumela eyimpumelelo kububanzi be-spectrum yesistimu, ama-algorithms abalulekile kanye nedizayini yezakhiwo.

Ngokuya ngobubanzi be-spectrum yesistimu, ngokusekelwe ku-C-band yendabuko, ububanzi be-spectrum yesistimu bunwetshwa futhi kumabhendi we-S no-L ukuze kufinyelelwe umkhawulokudonsa wokuxhumana omkhulu kakhulu we-S+C+L ama-multi-band afika ku-17THz, futhi Uhlu lwebhendi luhlanganisa i-1483nm-1627nm.

Ngokuphathelene nama-algorithms abalulekile, i-China Academy of Telecommunication Research ihlanganisa izici zokulahlekelwa kwe-fiber optical ye-S/C/L yama-band amathathu kanye nokudluliswa kwamandla, futhi ihlongoza uhlelo lokukhulisa ukusebenza kahle kwe-spectrum ngokufanisa okuguquguqukayo kwezinga lezimpawu, isikhawu sesiteshi nokuguquguquka. uhlobo lwekhodi. Ngesikhathi esifanayo, ngosizo lwe-ZTE ye-multi-band yokugcwalisa igagasi kanye nobuchwepheshe bokulinganisa amandla obuzenzakalelayo, ukusebenza kwesevisi yezinga lesiteshi kuyalingana futhi nebanga lokudlulisela liyakhuliswa.

Ngokuya ngedizayini yezakhiwo, ukudluliswa kwesikhathi sangempela kusebenzisa ubuchwepheshe obuthuthukisiwe bokuvala i-photoelectric sealing, izinga le-baud lesignali ye-single wave lidlula i-130GBd, isilinganiso sebhithi sifinyelela ku-1.2Tbit/s, futhi inani lezingxenye ze-photoelectric lilondolozwa kakhulu.

Ukuhlolwa kusebenzisa i-ultra-low attenuation kanye ne-optical fiber yendawo enkulu esebenzayo eyakhiwe yi-Changfei Company, ene-coefficient ephansi yokunciphisa kanye nendawo enkulu ephumelelayo, okusiza ukuqaphela ukunwetshwa kobubanzi be-spectral besistimu ku-S-band, kanye nenani eliphakeme kakhulu langempela- isikhathi sokulinganiswa kwegagasi elilodwa sifinyelela ku-1.2Tbit/s. Ii-fiber opticalibone ukwenziwa kwasendaweni komklamo, ukulungiselela, inqubo, izinto ezingavuthiwe nezinye izixhumanisi.

Ubuchwepheshe bobuhlakani bokwenziwa kanye nezinhlelo zebhizinisi zabo ziyadlondlobala, okuletha ukuqhuma kwesidingo somkhawulokudonsa wokuxhuma kwesikhungo sedatha. Njengesisekelo somkhawulokudonsa wengqalasizinda yolwazi lwedijithali, inethiwekhi ye-optical all-optical idinga ukuqhubeka inqamule izinga namandla okudluliswa kwe-optical. Ihambisana nomgomo "wokuxhumanisa okuhlakaniphile empilweni engcono", inkampani izohlanganyela izandla nabaqhubi namakhasimende ukugxila ocwaningweni nasekuthuthukisweni kobuchwepheshe obuyinhloko bokuxhumana okubonakalayo, ukwenza ukubambisana okujulile nokuhlola ezentengiselwano emikhakheni. wamanani amasha, amabhendi amasha, nemicu emisha yokubona, kanye nokwakha ukukhiqizwa kwekhwalithi entsha yamabhizinisi anobuhlakani obusha, ikhuthaza njalo ukuthuthukiswa okusimeme kwenethiwekhi yonke ye-optical, futhi isiza ukwakha isisekelo esiqinile sekusasa ledijithali.
