Ososayensi abavela emhlabeni wonke bathuthukise ngempumelelo ukusebenza kwama-amplifiers e-erbium-doped fiber (ama-EDFA), okwenza intuthuko enkulu emkhakheni wezokuxhumana kwe-optical.I-EDFAiyithuluzi elibalulekile lokuthuthukisa amandla ezimpawu zokukhanya kuma-fiber optical, futhi ukuthuthukiswa kokusebenza kwayo kulindeleke ukuthi kuthuthukise kakhulu amakhono ezinhlelo zokuxhumana ze-optical.
Ukuxhumana okubonakalayo, okuncike ekudlulisweni kwezibonakaliso zokukhanya ngemicu ye-optical, kushintshe izinhlelo zokuxhumana zesimanje ngokuhlinzeka ngokudluliselwa kwedatha okusheshayo nokuthembekile. Ama-EDFA adlala indima ebalulekile kule nqubo ngokukhulisa lezi zibonakaliso zokukhanya, andise amandla azo futhi aqinisekise ukudluliselwa okuphumelelayo emabangeni amade. Kodwa-ke, ukusebenza kwama-EDFA bekulokhu kulinganiselwe, futhi ososayensi bebesebenza ngokungakhathali ukuthuthukisa amakhono abo.
Impumelelo yakamuva ivela eqenjini lososayensi abaye bathuthukisa ngempumelelo ukusebenza kwama-EDFA ukuze bandise kakhulu amandla esignali yokukhanya. Le mpumelelo kulindeleke ukuthi ibe nomthelela omkhulu ezinhlelweni zokuxhumana zokukhanya, ikhulise ukusebenza kahle kanye namandla azo.
I-EDFA ethuthukisiwe ihlolwe kabanzi ngaphansi kwezimo zelebhu ngemiphumela ethembisayo kakhulu. Ososayensi babone ukwanda okukhulu kwamandla esignali ye-optical, kudlula imikhawulo yangaphambilini yama-EDFA avamile. Lokhu kuthuthukiswa kuvula amathuba amasha ezinhlelo zokuxhumana ze-optical, okuvumela amazinga okudlulisa idatha asheshayo futhi athembekile.
Intuthuko ezinhlelweni zokuxhumana ze-optical izozuzisa izimboni nemikhakha eyahlukene. Kusukela ku-telecom kuya esikhungweni sedatha, lawa ma-EDFA athuthukisiwe azohlinzeka ngokusebenza okuthuthukisiwe ukuqinisekisa ukudluliswa kwedatha okungenazihibe nokuphumelelayo. Lokhu kuthuthukiswa kubaluleke kakhulu enkathini yobuchwepheshe be-5G, njengoba isidingo sokudluliswa kwedatha okusheshayo nokunamandla aphezulu siqhubeka nokukhula kakhulu.
Abacwaningi abasungula le ntuthuko badunyiswe ngokuzinikela kwabo kanye nobuchwepheshe babo. Usosayensi oholayo weqembu, uDkt. Sarah Thompson, uchaze ukuthi ukuthuthukiswa kwe-EDFA kufezwe ngokuhlanganiswa kwezinto ezithuthukisiwe kanye nomklamo omusha. Lokhu kuhlanganiswa kuletha ukukhishwa kwamandla okwandisiwe, okuguqula ukusebenza kwezinhlelo zokuxhumana ze-optical.
Ukusetshenziswa okungenzeka kwalokhu kuthuthukiswa kukhulu kakhulu. Ngeke nje kuthuthukise ukusebenza kahle kwezinhlelo zokuxhumana ze-optical ezikhona, kodwa futhi kuzovula amathuba amasha ocwaningo nentuthuko emikhakheni ehlobene. Ukukhishwa kwamandla aphezulu kwama-EDFA kungasiza ekuthuthukiseni ubuchwepheshe obusha njengezinhlelo zokuxhumana ze-optical ezikude, ukusakaza ividiyo okunencazelo ephezulu kakhulu, kanye nokuxhumana okujulile.
Nakuba le ntuthuko ngokungangabazeki ibalulekile, ucwaningo olwengeziwe kanye nentuthuko kusadingeka ngaphambi kokuba i-EDFA ethuthukisiwe isetshenziswe ngezinga elikhulu. Izinkampani ezaziwayo embonini yezokuxhumana kanye nobuchwepheshe ziveze intshisekelo yokusebenzisana namaqembu esayensi ukuze kuthuthukiswe ubuchwepheshe futhi kubuhlanganise emikhiqizweni yabo.
Ukuthuthukiswa kweI-EDFA Kuphawula ingqophamlando ebalulekile emkhakheni wokuxhumana okubonakalayo. Ukukhishwa kwamandla okuthuthukisiwe kwalawa madivayisi kuzoshintsha ukusebenza kwezinhlelo zokuxhumana okubonakalayo, okuvumela ukudluliswa kwedatha okusheshayo nokuthembekile. Njengoba ososayensi beqhubeka nokucindezela imingcele yobuchwepheshe, ikusasa lokuxhumana okubonakalayo libonakala likhanya kakhulu kunanini ngaphambili.
