Emkhakheni wenethiwekhi ye-optical, ukusebenza kahle nokuthembeka yizici ezibalulekile zokuqinisekisa ukudluliswa kwedatha okungenamthungo. Njengoba ubuchwepheshe buqhubeka nokuthuthuka, isidingo sama-amplifiers asebenza kahle kakhulu siya ngokuya sibaluleke kakhulu. Kulapho ubuchwepheshe be-Erbium-Doped Fiber Amplifier (EDFA) buqala khona ukusebenza, buhlinzeka ngesixazululo esinamandla sokuthuthukisa ukusebenza kwenethiwekhi.
Esinye sezici ezivelele zeEDFAubuchwepheshe yikhono layo lokukhulisa amasignali okukhanya ngaphandle kokuwaguqula abe amasignali kagesi. Lokhu akwenzi kuphela inqubo yokukhulisa ibe lula kodwa futhi kunciphisa ubungozi bokuwohloka kwesignali. Ngokukhulisa ngokuqondile isignali yokubona, ubuchwepheshe be-EDFA buqinisekisa ukuthi idatha ihlala injalo phakathi nenqubo yokudlulisela.
Ukufakwa kwesistimu yokusebenza kwesikrini sokuthinta esigcwele kuthuthukisa kakhulu ukusebenza kobuchwepheshe be-EDFA. Ama-opharetha angafinyelela kalula futhi azulazule ngenani elikhulu lolwazi ngenxa yokusebenzelana okulula komsebenzisi, okuhlanganisa inkomba enemininingwane nesibonisi esinembile. Lokhu akwenzi nje kuphela ukusebenza kwedivayisi kube lula kodwa futhi kuvumela abasebenzisi ukuthi benze izinqumo ezinolwazi ngokusekelwe kudatha ecacile, yesikhathi sangempela. Indlela "okubonayo yilokho okutholayo" iqinisekisa ukuthi abasebenzisi bangasebenzisa okokusebenza kalula futhi kalula ngaphandle kwesidingo samamanyuwali abanzi noma ukuqeqeshwa.
Ngokungeziwe ku-interface yayo esebenziseka kalula, ubuchwepheshe be-EDFA bubuye bunamakhono okushintsha amangalisayo. Ukushintsha kwe-Optical okuhlanganiswe ngaphakathi kwesistimu kunikeza izikhathi zokushintsha ngokushesha kanye nokulahlekelwa kwesignali okuncane. Kungakhathaliseki ukuthi ukushintshwa okuzenzakalelayo noma ukushintsha okuphoqelelwe, ubuchwepheshe be-EDFA bunganikeza ukuguqulwa okungenamthungo nokwethenjelwa phakathi kwamasignali okukhanya, kuqinisekiswe ukugeleza kwedatha okuqhubekayo nokungaphazamiseki.
Izinzuzo zobuchwepheshe be-EDFA zidlulela ngale kwamakhono ayo obuchwepheshe. Umthelela wayo ekusebenzeni kwenethiwekhi ye-optical ujulile, inikeza isisombululo esingabizi kakhulu sokuthuthukisa ukusebenza kahle kokudluliswa kwedatha. Ngokunciphisa isidingo sokuguqulwa kwesignali kanye nokwandisa ubuqotho bezimpawu ezibonakalayo, ubuchwepheshe be-EDFA busiza ukudala ingqalasizinda yenethiwekhi ye-optical elula futhi enokwethenjelwa.
Ukwengeza, ukuguquguquka kobuchwepheshe be-EDFA kuyenza ibe yimpahla ebalulekile ezimbonini ezihlukahlukene ezifana nezokuxhumana kanye nezikhungo zedatha. Ingakwazi ukukhulisa amasignali okubona ngokunembile nangempumelelo, iyenze ibe yingxenye ebalulekile ekuthuthukisweni kwamanethiwekhi abonayo anesivinini esikhulu, anomthamo omkhulu.
Njengoba isidingo sokudluliswa kwedatha okungenamthungo siqhubeka sikhula, indima yobuchwepheshe be-EDFA ekuthuthukiseni ukusebenza kwenethiwekhi yokubona iya ngokuya ibaluleka. Inhlanganisela yayo yamakhono athuthukile okukhulisa i-amplification, isixhumi esibonakalayo esisebenziseka kalula namandla okushintsha angenamthungo akwenza kube yisixazululo esiphoqayo sezinhlangano ezifuna ukuthuthukisa ingqalasizinda yazo yenethiwekhi yokubona.
Ngamafuphi, ukuhlanganiswa kweEDFAubuchwepheshe buhlinzeka ngezindlela ezinamandla zokuthuthukisa ukusebenza kwamanethiwekhi okukhanya. Amakhono ayo okukhulisa i-amplification athuthukile, isixhumi esibonakalayo esisebenziseka kalula kanye namandla okushintsha angenamthungo ayenza ibe yimpahla ebalulekile ekuthuthukisweni kwamanethiwekhi okubona anesivinini esikhulu, namandla aphezulu. Ngokuthuthuka okuqhubekayo kobuchwepheshe, indima yobuchwepheshe be-EDFA ekuqinisekiseni ukudluliswa kwedatha okuphumelelayo nokuthembekile ngokungangabazeki izobaluleka kakhulu.
