Indlela yophuhliso lwe-fiber optics

I-China icebisa ukuthatha ukuphunyezwa korhulumente we-e kunye nokwakhiwa kwezixeko ezintsha ezikrelekrele njengesiqalo, kunye nokusebenzisa ukuhlanganiswa kwedatha kunye nokwabelana ngayo njengendlela yokwakha iziko ledatha elikhulu elidibeneyo lesizwe, ukukhuthaza ukuhlanganiswa kwetekhnoloji, ukuhlanganiswa kwamashishini, kunye nokuhlanganiswa kwedatha ukufezekisa ukuhlanganiswa kwamanqanaba aphesheya kunye naphesheya kwemimandla, ulawulo lwentsebenziswano kunye neenkonzo kwiinkqubo, amasebe, kunye namashishini. Uqoqosho lwedijithali olusekwe kwinethiwekhi ye-optical ekrelekrele luya kukhuthaza uphuhliso lwezixeko ezikrelekrele. Umzekelo, kushishino lwezemali, ukunciphisa nganye i-0.1 ms kwi-latency kunokunyusa umthamo wentengiselwano nge-10,000, kunye nesixa sentengiselwano ngaphezulu kwe-200 yezigidi zeeyuan. Ke ngoko, ukukhuthaza uphuhliso loqoqosho lwedijithali, kuyimfuneko ukuphuhlisa ngamandla iziseko zophuhliso ezisebenzisa i-optical kunye netekhnoloji ye-fiber optic ekhawulezayo, enamandla aphezulu.

Unxibelelwano lwe-fiber optic olukhawulezayo nolunamandla aphezulu luya kuba ngumqolo wamashishini asakhasayo. Iqhutywa ziinethiwekhi zonxibelelwano lwe-fiber optic ezineeleya ezininzi, imfuno ye-fiber optics kwiprojekthi ye-broadband yaseTshayina iyaqhubeka nokukhula. Umgama wokudluliselwa kwe-400G+G.654.E kwinkqubo ye-DWDM kulindeleke ukuba ufikelele [kumgama othile].Ifayibha ye-90 Gbaud enobude obunye ifikelela kwi-1500 km, ngelixa ifayibha ye-G.652 ifikelela kwi-800-900 km. Itekhnoloji yonxibelelwano enomthamo ophezulu esekelwe kwilahleko ephantsi kunye nendawo enkulu esebenzayo iya kuqhubeka nokuphuhliswa. Ngokuhambelana nesicwangciso somqhubi soyilo lwenkqubo ye-super 100G kunye nenethiwekhi yolwandle, iShenzhen Aixton Cables Co., Ltd. isebenzisa lonke uthotho lweshishini lonxibelelwano lwe-optical, idibanisa ngokupheleleyo inethiwekhi ye-optical kunye netekhnoloji yentambo ye-fiber optic, kwaye icebisa ukwakhiwa ngokuchanekileyo kwenethiwekhi ye-optical cable backbone yasekhaya esekelwe kwiNkqubo ye-G.654.E. Fiber Optic.

Uthumelo olusebenza kakuhle kunye netekhnoloji yentambo ye-fiber optic ye-G.654.E elawulwa ngokuzimeleyo. Xa ithelekiswa nentambo ye-G.652, amandla okukhanya entambo ye-G.654.E anokwandiswa malunga ne-2.0 dB. Xa isetyenziswa kwiindawo ezintsonkothileyo, inokuphucula kakhulu ukusebenza kothumelo lwe-400G kwaye yandise umgama wothumelo ngaphandle kokudluliselwa kombane. Intambo ye-fiber optic ye-Fiberhome ye-G.654.E, ebiyinxalenye yophuhliso lwe-fiber optic ye-China Telecom kangangeminyaka engaphezu kwama-40, yavela kwitekhnoloji yokuqala esebenzayo ye-fiber optic eTshayina. Inendawo enkulu esebenzayo, ilahleko ephantsi yothumelo, kunye nokumelana okunamandla kokugoba. Ngamalungelo epropathi yengqondo kunye namandla okulawula kulo lonke uthotho lweshishini, olu lwakhiwo lwentambo ye-optical entsha, enekhabhoni ephantsi, kwaye inobuhlobo nokusingqongileyo ifanelekile kwiinkqubo ze-400G.
