Ososayensi abavela emhlabeni wonke bathuthukise ngempumelelo ukusebenza kwe-erbium-doped fiber amplifiers (EDFAs), okwenza impumelelo enkulu emkhakheni wezokuxhumana optical.EDFAiyithuluzi eliyinhloko lokuthuthukisa amandla amasignali optical kumafiber optical, futhi ukuthuthukiswa kokusebenza kwayo kulindeleke ukuthi kuthuthukise kakhulu amandla ezinhlelo zokuxhumana ze-optical.
Izokuxhumana zamehlo, ezithembele ekudluliselweni kwezimpawu zokukhanya ngemicu yokubona, ziguqule izinhlelo zokuxhumana zesimanje ngokuhlinzeka ngokudluliswa kwedatha okushesha futhi okuthembekile. Ama-EDFA adlala indima ebalulekile kule nqubo ngokukhulisa lezi zimpawu zokukhanya, akhulise amandla awo futhi aqinisekise ukudluliswa okuphumelelayo kumabanga amade. Nokho, ukusebenza kwama-EDFA bekulokhu kunomkhawulo, futhi ososayensi bebesebenza ngokuzikhandla ukuthuthukisa amakhono abo.
Ukuphumelela kwakamuva kuvela eqenjini lososayensi abathuthukise ngempumelelo ukusebenza kwama-EDFA ukuze bakhulise kakhulu amandla esignali yokubona. Le mpumelelo kulindeleke ukuthi ibe nomthelela omkhulu ezinhlelweni zokuxhumana ngokukhanya, ikhulise ukusebenza kahle kwazo namandla.
I-EDFA ethuthukisiwe iye yahlolwa kabanzi ngaphansi kwezimo zaselabhorethri ngemiphumela ethembisa kakhulu. Ososayensi babone ukwanda okukhulu kwamandla esignali yokubona, okudlula imingcele yangaphambilini yama-EDFA avamile. Lokhu kuthuthukiswa kuvula amathuba amasha ezinhlelo zokuxhumana ezibonakalayo, okuvumela amazinga okudlulisa idatha asheshayo nathembekile.
Intuthuko ezinhlelweni zokuxhumana optical izohlomulisa izimboni nemikhakha eyahlukene. Kusukela ku-telecom kuya kusikhungo sedatha, lawa ma-EDFA athuthukisiwe azohlinzeka ngokusebenza okuthuthukisiwe ukuze kuqinisekiswe ukudluliswa kwedatha okungenazihibe futhi okuphumelelayo. Lokhu kuthuthukiswa kubaluleke kakhulu esikhathini sobuchwepheshe be-5G, njengoba isidingo sokudluliswa kwedatha ngesivinini esiphezulu nesiphezulu siqhubeka sikhula kakhulu.
Abacwaningi abagqugquzele leli phuzu batuswe ngokuzinikela kanye nobuchule babo. Usosayensi oholayo weqembu, uDkt Sarah Thompson, wachaza ukuthi ukuthuthukiswa kwe-EDFA kufinyelelwe ngenhlanganisela yezinto ezithuthukisiwe kanye nemiklamo emisha. Le nhlanganisela iletha ukuphuma kwamandla akhulisiwe, iguqula ukusebenza kwezinhlelo zokuxhumana ezibonayo.
Izinhlelo zokusebenza ezingaba khona zalokhu kuthuthukiswa zinkulu kakhulu. Ngeke nje ithuthukise ukusebenza kahle kwezinhlelo ezikhona zokuxhumana nge-optical, kodwa futhi izovula amathuba amasha ocwaningo nokuthuthukiswa emikhakheni ehlobene. Amandla aphezulu aphumayo we-EDFA angasiza ukuthuthukiswa kobuchwepheshe obusha njengamasistimu okuxhumana okubona amabanga amade, ukusakazwa kwevidiyo okunencazelo ephezulu kakhulu, kanye nokuxhumana endaweni ejulile.
Nakuba le mpumelelo ngokungangabazeki ibalulekile, ucwaningo olwengeziwe nokuthuthukiswa kusadingeka ngaphambi kokuba i-EDFA ethuthukisiwe iqaliswe ngezinga elikhulu. Izinkampani ezaziwayo ezimbonini zezokuxhumana nobuchwepheshe ziye zazwakalisa intshisekelo yokusebenzisana namaqembu esayensi ukuze kucwengwe ubuchwepheshe futhi buhlanganiswe emikhiqizweni yabo.
Ukuthuthukiswa kweEDFA kuphawula ingqopha-mlando ebalulekile emkhakheni wokuxhumana nge-optical. Ukukhipha amandla okuthuthukisiwe kwalawa madivayisi kuzoshintsha ukusebenza kwezinhlelo zokuxhumana ezibona ngamehlo, kuvumele ukudluliswa kwedatha okushesha futhi okuthembeke kakhulu. Njengoba ososayensi beqhubeka nokuphusha imingcele yobuchwepheshe, ikusasa lezokuxhumana nge-optical libukeka liqhakazile kunangaphambili.
