Ngokukhanya, sinokubona iintyatyambo kunye nezityalo ezisingqongileyo kunye nehlabathi.Ayiphelelanga apho, kodwa “ngokukhanya”, sinokudlulisela inkcazelo, ebizwa ngokuba lunxibelelwano lwefiber-optic.” Iphephancwadi iScientific American” lakha lagqabaza lathi: “Unxibelelwano ngefayibha yenye yezinto ezine ezibalulekileyo ezayilwayo ukususela kwiMfazwe Yehlabathi II. unxibelelwano lwefiber-optic, bekungayi kubakho i-Intanethi kunye nothungelwano lonxibelelwano namhlanje.”
Unxibelelwano lwefiber optical yindlela yonxibelelwano apho amaza okukhanya asetyenziswa njengesithwala kunye neefibers optical okanye iifiber optical fibers zisetyenziswa njengendawo yokudlulisa.Imvelaphi yonxibelelwano “lokukhanya” ngokwengqiqo yale mihla ibuyela emva kwifowuni yamehlo eyaqanjwa nguBell ngo. I-1880.Ifowuni ye-optical iquka umthombo wokukhanya wesibane se-arc, i-microphone efumana ukukhanya kokukhanya ekuphenduleni isandi, kunye nommkeli obuyisela isandi sokuqala somsindo.Umgaqo-siseko kukuba ilizwi lomthumeli liguqulwa libe ngumqondiso we-optical .Emva kokudluliselwa, umamkeli ubuyela kwisignali yombane, kwaye uphawu lombane lubuyiselwa kwifowuni yelizwi.
Nangona unxibelelwano "lokukhanya" lunesiqalo esihle, kodwa ixesha elide, iteknoloji yonxibelelwano yefiber-optic ayizange iphuhliswe kakuhle.Okokuqala, ngenxa yokuba akukho mthombo wokukhanya ofanelekileyo wafunyanwa.Okwesibini, kwakungekho ndlela efanelekileyo yokuhambisa iimpawu ze-optical.In ngoo-1960, ukuzalwa kweelaser zerubhi kwaphefumlela izazinzulu.IiLasers zinezibonelelo zespectrum emxinwa, ulwalathiso olulungileyo, kunye nokuphindaphindeka okuphezulu kunye nesigaba sokufana, okubenza babe ngumthombo ofanelekileyo wonxibelelwano lwefayibha-optic. Ngo-1966, owaphumelela iBhaso leNobel uGao Song wenza isindululo sokusetyenziswa kwefiber yeglasi yequartz (oko kukuthi, ifayibha yamehlo, ekubhekiswa kuyo. njengefiber optical) njengesixhobo sonxibelelwano lwamehlo.Ngokusekelwe kule nkcazo-bungcali, ngo-1970, iNkampani yaseCorning yaseUnited States yachitha izigidi ezingama-30 zeedola zaseMelika ukuvelisa iisampulu ezintathu zomsinga wobude obuziimitha ezingama-30, eziludidi lokuqala ehlabathini olunomsebenzi osebenzayo. ixabiso lonxibelelwano lwefiber-optic.Kweli nqanaba, itekhnoloji yonxibelelwano lwefiber optical ingenise entwasahlobo yophuhliso.
Unxibelelwano lwefiber optical ikakhulu luqulunqwe ngamalungu amathathu, ifayibha yamehlo, isidluliseli samehlo kunye nesamkeli samehlo.Ngokufutshane, i-transmitter ye-optical inokuguqula isignali ye-original kwi-signal optical, ethunyelwa kwi-receiver optical ngokusebenzisa i-fiber optical channel, kwaye ekugqibeleni i-receiver optical ibuyisela uphawu olufunyenweyo kwisignali yokuqala.
Abantu baye bazama ukuphuhlisa iteknoloji yonxibelelwano lwefiber-optic ngenxa yokuba ayinayo kuphela inzuzo ephezulu yobugcisa kodwa inamandla okhuphiswano lwezoqoqosho xa kuthelekiswa neendlela zangaphambili zonxibelelwano. ukogqitha ubuninzi bee-microwaves ukusuka kwi-1 GHz ukuya kwi-10 GHz. Oku kuthetha ukuba umthamo wolwazi wonxibelelwano lwamehlo uphezulu ngokuphindwe kayi-10,000 kunoo-omatshini be-microwaves. Ukongeza, unxibelelwano lwefiber-optic lukwanesakhono sokuchasana nokuphazamiseka, esifana ne-anti-interference. ingxolo yangasemva kunye nokuphazamiseka kwe-anti-electromagnetic, enokuqinisekisa ubumfihlo bonxibelelwano kunye nokhuseleko kwinqanaba elithile, kwaye ubungakanani buncinci kwaye kulula ukububeka.
Namhlanje, unxibelelwano lwe-fiber-optic lusetyenziswa kakhulu kuthungelwano lonxibelelwano, i-Intanethi, kunye nothungelwano lwentambo zikamabonwakude.Iphuhlisa kwicala lesantya esiphezulu, ukupakishwa, uthungelwano, kunye nobukrelekrele, ukufaka amandla amatsha kwindawo yonxibelelwano. Nangona kunjalo, ngokunyuka ngokukhawuleza kwesicelo se-intanethi ye-intanethi, i-computing yefu, idatha enkulu kunye ne-Intanethi yezinto, Ukunyuka kwetrafikhi kuzisa imiceli mngeni emikhulu kuthungelwano lolwazi kunye nonxibelelwano, kwaye ukusombulula ingxaki "yokukhula ngokukhawuleza" kokuhamba kwedatha yenethiwekhi iba ngumhlaba okhuphisanayo kwinkalo yolwazi kunye nonxibelelwano lwehlabathi.
