Ngexesha le-5G kwane-6G, apho iividiyo ezikumgangatho ophezulu zithunyelwa ngemizuzwana kwaye idatha enkulu itshintshiselwana ngoko nangoko, "amandla angaqondakaliyo" afihla ngasemva kweziganeko—iikhompawundi zomhlaba ezingaqhelekanga. Zibonakala ziphantsi, zidlala indima engenakutshintshwa kunxibelelwano lwefayibha ye-optical.
Unxibelelwano lwefayibha ye-optical lufana "nendlela enkulu yolwazi," kwaye iikhompawundi zomhlaba ezingaqhelekanga "ziinjineli eziphambili" kule ndlela. Okokuqala, iifayibha ze-optical ezinqabileyo zomhlaba zikhulisa kakhulu ukusebenza kakuhle kothumelo. Ngokwandisa isalathisi sokurhawuzelela sentliziyo, ziphucula uthumelo lokukhanya, zivumela idatha ukuba idlule kwiifayibha "ngesantya sokukhanya" njengololiwe okhawulezayo, nto leyo ephucula kakhulu ukusebenza kakuhle kothumelo.
Uthumelo olude lusoloko lujongene nengxaki enzima yokuncitshiswa kwesignali kunye nokuphambuka. Ii-Rare earth compounds zisombulula oku ngempumelelo ngokunciphisa iziphumo ezingezizo ezithe ngqo kwiifayibha—njengokufaka "isizinzisi" sesignali. Oku kunciphisa ukuncitshiswa kunye nokuphambuka, kuqinisekisa uthumelo oluzinzileyo kwaye kuphucula kakhulu ukuthembeka kwenkqubo.
Iimeko ezahlukeneyo zonxibelelwano zifuna ubude be-optical obahlukeneyo. Ngeempawu zazo ezizodwa, ii-rare earth compounds zivumela ukulungiswa okuguquguqukayo kwe-wavelengths ngokulungelelanisa ubuninzi be-doping. Oku kuvumela unxibelelwano lwe-optical fiber ukuba luhambelane nezicelo ezahlukeneyo, ukusuka kwi-telemedicine kunye nokusasazwa bukhoma kwe-HD ukuya kuthumelo lwedatha olukrelekrele.
Ngexesha lokudluliselwa kwesignali kumgama omde, iifayibha ezinqabileyo ezifakwe emhlabeni zikwasebenza “njengezikhululo zegesi zesignali.” Nge-gain ephezulu kunye ne-bandwidth ebanzi yokwanda, ziyandisa imiqondiso ye-optical ebuthathaka, zandisa umgama wokudluliselwa kwaye ziphucula umgangatho—njengokuhlaziya isignali ediniweyo ibe ngamandla apheleleyo.
Ukongeza, iifayibha ezifakwe kwi-cerium zisebenza indima ekhethekileyo njenge-laser media kwiinkqubo zonxibelelwano lwe-optical, zibonelela ngemithombo yokukhanya ezinzileyo kwii-laser.
Ukususela ekuphuculeni ukusebenza kakuhle kothumelo ukuya ekuzinziseni imiqondiso, ukulungisa ubude be-wavelengths ngendlela eguquguqukayo, ukukhulisa imiqondiso, kunye nokusebenza njenge-laser media, ii-rare earth compounds ziphucula ngokupheleleyo ukusebenza konxibelelwano lwe-optical fiber. Ziqinisa uzinzo lwenkqubo kunye nokuguquguquka, zibeka isiseko esiqinileyo sokwakha iinethiwekhi zonxibelelwano ze-optical zanamhlanje ezikhawulezayo nezinomthamo omkhulu. Njengoko itekhnoloji iqhubela phambili, i-rare earths ikulungele ukudlala indima enkulu ngakumbi kunxibelelwano lwe-optical, izisa amava onxibelelwano akhawulezayo, azinzileyo kwaye iqhubela phambili uphuhliso olukhawulezayo lwexesha ledijithali.
