I-China iphakamisa ukuthatha ukuqaliswa kohulumeni we-e kanye nokwakhiwa kwamadolobha amasha ahlakaniphile njengendawo yokuqala, nokusebenzisa ukuhlanganisa idatha kanye nokwabelana njengendlela yokwakha isikhungo sedatha esikhulu esihlanganisiwe sikazwelonke, ukukhuthaza ukuhlanganiswa kobuchwepheshe, ukuhlanganiswa kwamabhizinisi, kanye nokuhlanganiswa kwedatha ukuze kufezwe ukuhlanganiswa kwezinga eliphakathi kanye nelesifunda, ukuphathwa ngokubambisana kanye nezinsizakalo kuzo zonke izinhlelo, iminyango, kanye namabhizinisi. Umnotho wedijithali osekelwe kunethiwekhi ye-optical ehlakaniphile uzokhuthaza ukuthuthukiswa kwamadolobha ahlakaniphile. Isibonelo, embonini yezezimali, ukunciphisa ngakunye kwe-0.1 ms kokulibaziseka kungandisa ivolumu yokuthengiselana ngo-10,000, kanye nenani lokuthengiselana ngama-yuan angaphezu kwezigidi ezingu-200. Ngakho-ke, ukuze kukhuthazwe intuthuko yomnotho wedijithali, kubalulekile ukuthuthukisa ngamandla ingqalasizinda ye-optical yonke kanye nobuchwepheshe be-fiber optic obusheshayo, obunamandla aphezulu.
Ukuxhumana kwe-fiber optic okusheshayo nokunamandla aphezulu kuzoba umgogodla wezimboni ezisafufusa. Njengoba kuqhutshwa amanethiwekhi okuxhumana kwe-fiber optic anezingqimba eziningi, isidingo se-fiber optics kuphrojekthi ye-broadband yaseShayina siyaqhubeka nokukhula. Ibanga lokudlulisela elingu-400G+G.654.E ohlelweni lwe-DWDM kulindeleke ukuthi lifinyelele [ibanga elithile].I-fiber engu-90 Gbaud enobude obulodwa obuyi-1500 km, kanti i-fiber engu-G.652 ifinyelela ku-800-900 km. Ubuchwepheshe bokuxhumana obunamandla aphezulu obusekelwe ekulahlekelweni okuphansi kanye nendawo enkulu ephumelelayo buzoqhubeka nokuthuthukiswa. Ngokuhambisana nohlelo lomqhubi lokuklama uhlelo lwe-super 100G kanye nenethiwekhi yasolwandle, i-Shenzhen Aixton Cables Co., Ltd. isebenzisa lonke uchungechunge lwemboni yokuxhumana kwe-optical, ihlanganisa ngokugcwele ubuchwepheshe benethiwekhi ye-optical kanye nekhebula le-fiber optic, futhi iphakamisa ukwakhiwa okunembile kwenethiwekhi yomgogodla wekhebula le-optical lasekhaya elisekelwe kuhlelo lwe-G.654.E. Fiber Optic.
Ukudluliselwa kokusebenza okuphezulu kanye nobuchwepheshe bekhebula le-fiber optic le-G.654.E elilawulwa ngokuzimela. Uma kuqhathaniswa ne-fiber ye-G.652, amandla okukhanya e-fiber ye-G.654.E angandiswa cishe ngo-2.0 dB. Uma isetshenziswa ezindaweni eziyinkimbinkimbi, ingathuthukisa kakhulu ukusebenza kokudluliselwa kwe-400G futhi yandise ibanga lokudlulisela ngaphandle kokudluliselwa kukagesi. Ikhebula le-fiber optic le-Fiberhome le-G.654.E, elibe yingxenye yokuthuthukiswa kwe-fiber optic ye-China Telecom iminyaka engaphezu kwengu-40, laqala ngobuchwepheshe bokuqala obusebenzayo be-fiber optic eShayina. Linendawo ephumelelayo enkulu, ukulahlekelwa kokudluliselwa okuphansi, kanye nokumelana okunamandla kokugoba. Ngamalungelo obunikazi bobuhlakani kanye namakhono okulawula kulo lonke uchungechunge lwemboni, lesi sakhiwo sekhebula le-optical esisha, esinekhabhoni ephansi, futhi esinobungani nemvelo silungele izinhlelo ze-400G.
