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 kokudluliselwa kwamandla amakhulu e-S+C+L, izinga eliphakeme kakhulu lesikhathi sangempela le-wave elilodwa lifinyelele ku-1.2Tbit/s, kanye nezinga lokudluliswa kokuqondisa okulodwai-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.

Ngokobubanzi 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 we-multi-band kufika ku-17THz, futhi ububanzi bebhendi buhlanganisa i-1483nm-1627nm.

Ngokuphathelene nama-algorithms abalulekile, i-China Academy of Telecommunication Research ihlanganisa izici zokulahlekelwa kwe-fiber optical ye-S/C/L ye-three-band kanye nokudluliselwa kwamandla, futhi iphakamisa uhlelo lokukhulisa ukusebenza kahle kwe-spectrum ngokufanisa okuguquguqukayo kwezinga lezimpawu, isikhawu sesiteshi kanye nohlobo lwekhodi yokushintshashintsha. 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 ukuncishiswa okuphansi kakhulu kanye ne-fiber ebonakalayo yendawo enkulu esebenzayo ethuthukiswe yiNkampani ye-Changfei, ene-coefficient ephansi yokunciphisa kanye nendawo esebenza kahle enkulu, okusiza ukuqaphela ukunwetshwa kobubanzi be-spectral besistimu ku-S-band, kanye nezinga eliphezulu lesikhathi sangempela legagasi elilodwa lifinyelela 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 "wokuxhuma okuhlakaniphile kwempilo engcono", inkampani izohlanganisa izandla nabaqhubi kanye namakhasimende ukugxila ocwaningweni nasekuthuthukisweni kobuchwepheshe obuyinhloko bokuxhumana optical, ukwenza ukubambisana okujulile nokuhlola kwezentengiselwano emikhakheni yamanani amasha, amabhendi amasha, kanye nemicu emisha yokukhanya, futhi yakhe ukukhiqizwa kwekhwalithi entsha yezinkampani ezithuthukayo, njalonjalo, ukuthuthukiswa kwenethiwekhi ye-innovation. futhi usize ukwakha isisekelo esiqinile sekusasa ledijithali.
