I-China ihlongoza ukuthatha ukuqaliswa kokusebenza kukahulumeni we-elekthronikhi kanye nokwakhiwa kwamadolobha amasha ahlakaniphile njengesiqalo, futhi isebenzise ukuhlanganisa idatha phakathi nokwabelana njengendlela yokwakha isikhungo sedatha esikhulu sikazwelonke esididiyelwe sikazwelonke, sikhuthaze ukuhlanganiswa kwezobuchwepheshe, ukuhlanganiswa kwebhizinisi kanye nedatha. ukuhlanganiswa ukuze kuzuzwe ukuhlanganiswa phakathi kwamazinga naphakathi kwezifunda. , Ukuphathwa ngokubambisana kanye nezinsizakalo phakathi kwezinhlelo, phakathi kweminyango naphakathi kwezinkampani. Umnotho wedijithali osuselwe kunethiwekhi ye-smart optical uzokhuthaza ukuthuthukiswa kwamadolobha ahlakaniphile. Isibonelo, embonini yezezimali, ukuncishiswa ngakunye kokulibaziseka okungu-0.1 ms kungakhuphula ivolumu yokwenziwayo ngo-10,000, futhi inani lomsebenzi lizokhuphuka ngamayuan angaphezu kwezigidi ezingu-200. Ngakho-ke, ukuze kuthuthukiswe ukuthuthukiswa komnotho wedijithali, kuyadingeka ukuthuthukisa ngamandla izisekelo ze-optical futhi kuthuthukiswe ubuchwepheshe be-fiber optical high-speed kanye nomthamo omkhulu.
Ukuxhumana kwe-fiber optic okunesivinini esikhulu, okunamandla amakhulu kuzoba ukusekelwa okuyisisekelo kwezimboni ezintsha. Iqhutshwa amanethiwekhi okuxhumana ayindilinga amaningi optical fiber, isidingo samafiber optical ekwakhiweni kolwazi olubanzi lwaseChina siyaqhubeka nokukhula. Ibanga lokudlulisela lika-400G+G.654.E kusistimu ye-lon DWDM lilindelekileIjubane elilodwa lamagagasi angu-90 Gbaud lifinyelela ku-1500 km, kanti ku-G.652 fiber lingu-800-900 km. Ubuchwepheshe bokuxhumana obunamandla amakhulu obusekelwe ekulahlekeni okuphansi kanye nendawo enkulu ephumelelayo buzoqhubeka nokuthuthukiswa. Ngokohlelo lomsebenzisi lokuklama uhlelo lwe-super 100G kanye nenethiwekhi yasolwandle, i-shenzhen Aixton cables co., Ltd isebenzisa uchungechunge lwezimboni ze-optical communication, ihlanganisa ngokugcwele inethiwekhi ye-optical kanye nobuchwepheshe bekhebula le-fiber optic, futhi iphakamisa ukwakhiwa okunembile kwe-Optical Cable Home. I-Backbone Network esekelwe kuhlelo lwe-G.654.E Fiber Optic.
Ukudlulisa ukusebenza okuphezulu nobuchwepheshe bekhebula le-fiber optic elilawulekayo le-G.654.E. Uma kuqhathaniswa nefayibha ye-G.652, amandla okubona e-G.654.E fiber angakhuliswa cishe ngo-2.0 dB. Uma isetshenziswa ezindaweni eziyinkimbinkimbi, ingathuthukisa kakhulu ukusebenza kokudlulisela kwe-400G futhi yandise ibanga lokudlulisela ngaphandle kokudluliselwa kukagesi. I-Fiberhome's G.654.E i-optical fiber, ebambelela emvuleni yefayibha yase-China Telecom iminyaka engaphezu kwengu-40, yavela kubuchwepheshe bokuqala obusebenzayo be-fiber optic e-China, enendawo enkulu ephumelelayo, ukulahlekelwa ukudluliselwa okuphansi nokumelana nokugoba okunamandla, ngobuhlakani. amalungelo empahla kanye nokulawulwa kwawo wonke uchungechunge lwezimboni, kusakhiwo esisha sekhebula le-carbon ephansi kanye nemvelo enobungane, singahlangabezana nokusetshenziswa okuhle kwesistimu ye-400G.
