Ososayensi abavela emhlabeni wonke bathuthukise ngempumelelo ukusebenza kwe-amplifiers ye-erbium-doped fiber amplifiers (EDFAS), benza impumelelo enkulu emkhakheni wezokuxhumana.I-EdfaIngabe idivaysi ebalulekile yokuthuthukisa amandla amasiginali we-optical on Fibers obonakalayo, futhi ukuthuthukiswa kokusebenza kwawo kulindeleke ukuthi kuthuthukiswe kakhulu amakhono ezinhlelo zokuxhumana ze-optical.
Ezokuxhumana ze-Optical, ezincike ekudluliseni kwamasiginali akhanyayo ngokusebenzisa imicu yanamuhla, shintshe izinhlelo zokuxhumana zanamuhla ngokunikeza ukuhanjiswa kwedatha okusheshayo nokwethembekile. U-Edfas udlala indima ebalulekile kule nqubo ngokukhulisa lezi zibonakaliso zokukhanya, wandisa amandla awo kanye nokuqinisekisa ukudluliselwa okusebenzayo kumabanga amade. Kodwa-ke, ukusebenza kwe-EDFAS bekulokhu kulinganiselwe, futhi ososayensi bebelokhu besebenza ngokungakhathali ukuthuthukisa amakhono abo.
Ukuphumelela kwakamuva kuvela eqenjini lososayensi abathuthukise ngempumelelo ukusebenza kwe-EDFAs ukuze bandise kakhulu amandla wesiginali ebonakalayo. Lokhu kufinyelelwa kulindeleke ukuba kube nomthelela omkhulu ezinhlelweni zokuxhumana ze-Optical, okwandisa ukusebenza kwazo kanye namandla.
I-Edfa ethuthukisiwe ivivinywe kakhulu ngaphansi kwezimo zelebhu ngemiphumela ethembisa kakhulu. Ososayensi babona ukwanda okukhulu kwamandla wesiginali yamehlo, kudlula imikhawulo edlule yama-EDFA ajwayelekile. Lokhu kuthuthukiswa kuvula amathuba amasha wezinhlelo zokuxhumana ze-Optical, enika amandla amanani okudlulisela okusheshayo nangokuthe xaxa kwedatha.
Intuthuko ezinhlelweni zokuxhumana ze-Optical izosizakala izimboni nemikhakha ehlukahlukene. Ukusuka ku-telecom kuya esikhungweni sedatha, lezi ze-edfas ezithuthukisiwe zizonikeza ukusebenza okuthuthukile ukuze kuqinisekiswe ukuhanjiswa kwedatha okungenamthungo kanye nokusebenza kahle. Lokhu kuthuthukiswa kubaluleke kakhulu esikhathini sobuchwepheshe be-5g, njengoba isidingo sesivinini esiphakeme kanye nokudluliswa kwedatha ephezulu kuyaqhubeka ukukhula ngokubonakalayo.
Abaphenyi ngemuva kwempumelelo badunyiswe ukuzinikezela kwabo nobuchwepheshe babo. Usosayensi weqembu leqembu, uDkt Sarah Thompson, wachaza ukuthi ukuthuthuka kwe-EDFA kutholakala ngokuhlanganiswa kwezinto ezithuthukisiwe kanye nokwakhiwa okusha. Le nhlanganisela iletha okukhishwe kwamandla amplified Power, ukuguqula ukusebenza kwezinhlelo zokuxhumana ze-Optical.
Ukusetshenziswa okungenzeka kwalokhu kuthuthukiswa kukhulu. Ngeke kuthuthukise ukusebenza kahle kwezinhlelo ezikhona zokuxhumana ezikhona, kepha futhi zivule amathuba amasha ocwaningo kanye nentuthuko emikhakheni ehlobene. Ukukhishwa kwamandla okuphezulu kwe-EDFAS kungasiza ukuthuthukiswa kobuchwepheshe obusha obufana nezinhlelo zokuxhumana zebanga elide, ukusakazwa kwevidiyo okuvezwa ngencazelo ephezulu, kanye nokuxhumana okujulile kwesikhala.
Ngenkathi lokhu kuqhuma ngokungangabazeki kubalulekile, ukucwaninga okwengeziwe kanye nentuthuko kusadingeka ngaphambi kokuthi i-EdFA ethuthukisiwe ingayenziwa ngezinga elikhulu. Izinkampani ezaziwayo ezimbonini zezokuxhumana nezobuchwepheshe ziveze intshisekelo yokusebenzisana namaqembu esayensi ukucwilisa ubuchwepheshe futhi ahlanganise nemikhiqizo yawo.
Ukuthuthukiswa kweI-Edfa Imaka ingqophamlando emkhakheni wokuxhumana okubonakalayo. Ukukhishwa kwamandla okuthuthukisiwe kwalawa madivaysi kuzoshintsha ukusebenza kwezinhlelo zokuxhumana ze-Optical, ukunika amandla ukuhanjiswa kwedatha okusheshayo nokuthe xaxa. Lapho ososayensi beqhubeka nokucindezela imingcele yezobuchwepheshe, ikusasa lezokuxhumana okubona libukeka likhanya kunangaphambili.
