Emkhakheni wenethiwekhi ye-optical, ukusebenza kahle nokuthembeka kuyizinto ezibalulekile ukuqinisekisa ukudluliswa kwedatha okungenamthungo. Njengoba ubuchwepheshe buqhubeka nokuthuthuka, isidingo sama-amplifier e-optical asebenza kahle siba yinto ebaluleke kakhulu. Yilapho ubuchwepheshe be-Erbium-Doped Fiber Amplifier (EDFA) buqala khona ukusebenza, buhlinzeka ngesisombululo esinamandla sokuthuthukisa ukusebenza kwenethiwekhi.
Esinye sezici ezivelele ze-I-EDFAubuchwepheshe buyikhono labo lokukhulisa izimpawu ezibonakalayo ngaphandle kokuziguqula zibe izimpawu zikagesi. Lokhu akugcini nje ngokwenza inqubo yokukhulisa ibe lula kodwa futhi kunciphisa ingozi yokuwohloka kwezimpawu. Ngokukhulisa ngokuqondile isignali ebonakalayo, ubuchwepheshe be-EDFA buqinisekisa ukuthi idatha ihlala ingashintshi kuyo yonke inqubo yokudlulisa.
Ukufakwa kohlelo lokusebenza lwesikrini sokuthinta esigcwele kuthuthukisa ukusebenza kobuchwepheshe be-EDFA. Abasebenzi bangafinyelela kalula futhi bazulazule ulwazi oluningi ngenxa yesixhumi esibonakalayo esisebenziseka kalula, okuhlanganisa inkomba enemininingwane kanye nesibonisi esibonakalayo. Lokhu akugcini nje ngokwenza kube lula ukusebenza kwedivayisi kodwa futhi kwenza abasebenzisi bakwazi ukwenza izinqumo ezinolwazi ngokusekelwe kudatha ecacile, yesikhathi sangempela. Indlela ethi "lokho okubonayo yilokho okutholayo" iqinisekisa ukuthi abasebenzisi bangayisebenzisa imishini kalula futhi kalula ngaphandle kwesidingo sezincwadi eziningi noma ukuqeqeshwa.
Ngaphezu kwesixhumi esibonakalayo esisebenziseka kalula, ubuchwepheshe be-EDFA buphinde bube namakhono okushintsha amangalisayo. Ama-optical switch ahlanganiswe ngaphakathi kohlelo ahlinzeka ngezikhathi zokushintsha okusheshayo kanye nokulahleka okuncane kwesignali. Kungakhathaliseki ukuthi ukushintsha okuzenzakalelayo noma ukushintsha ngesandla okuphoqelelwe, ubuchwepheshe be-EDFA bunganikeza ukuguqulwa okungenamthungo nokuthembekile phakathi kwamasignali optical, okuqinisekisa ukugeleza kwedatha okuqhubekayo nokungaphazanyiswa.
Izinzuzo zobuchwepheshe be-EDFA zidlulela ngale kwamakhono azo obuchwepheshe. Umthelela wazo ekusebenzeni kwenethiwekhi ye-optical ujulile, unikeza ikhambi elingabizi kakhulu lokuthuthukisa ukusebenza kahle kokudlulisa idatha. Ngokunciphisa isidingo sokuguqulwa kwesignali nokukhulisa ubuqotho besignali ye-optical, ubuchwepheshe be-EDFA buyasiza ekudaleni ingqalasizinda yenethiwekhi ye-optical elula futhi ethembekile.
Ngaphezu kwalokho, ukuguquguquka kobuchwepheshe be-EDFA kuyenza ibe yimpahla ebalulekile emikhakheni eyahlukene njengezokuxhumana kanye nezikhungo zedatha. Ingakhulisa izimpawu zokukhanya ngokunembile nangokusebenza kahle, okwenza kube yingxenye ebalulekile ekuthuthukisweni kwamanethiwekhi okukhanya asheshayo, anamandla amakhulu.
Njengoba isidingo sokudluliselwa kwedatha okungenazihibe siqhubeka nokukhula, indima yobuchwepheshe be-EDFA ekuthuthukiseni ukusebenza kwenethiwekhi ye-optical iba yinto ebaluleke kakhulu. Ukuhlanganiswa kwayo kwamakhono okukhulisa athuthukile, isikhombikubona esisebenziseka kalula kanye namakhono okushintsha okungenazihibe kwenza kube yisisombululo esikhangayo ezinhlanganweni ezifuna ukwenza ngcono ingqalasizinda yazo yenethiwekhi ye-optical.
Ngamafuphi, ukuhlanganiswa kweI-EDFAubuchwepheshe buhlinzeka ngendlela enamandla yokuthuthukisa ukusebenza kwamanethiwekhi okukhanya. Amakhono ayo okukhulisa athuthukisiwe, isikhombikubona esisebenziseka kalula kanye namakhono okushintshana angenamthungo kwenza kube yimpahla ebalulekile ekuthuthukiseni amanethiwekhi okukhanya asheshayo, anomthamo ophezulu. Ngokuthuthuka okuqhubekayo kobuchwepheshe, indima yobuchwepheshe be-EDFA ekuqinisekiseni ukudluliswa kwedatha okusebenzayo nokuthembekile ngokungangabazeki izoba yinto ebaluleke kakhulu.
