Ekuthuthukisweni kwamanethiwekhi okuxhumana aphezulu aphezulu aphezulu, ubuchwepheshe be-fiber optical budlala indima eyisisekelo nebalulekile.I-Fiby Optic Attenuator, isakhi esibalulekile se-Fiber Optict Network, iyithuluzi elisemqoka ukuqinisekisa ikhwalithi yokudluliselwa kwesiginali ye-Optical.Umsebenzi wayo oyinhloko ukunciphisa ukuqina kwamasiginali we-optical ukwenza ngcono ukusebenza kwezinhlelo zokuxhumana.Le ndatshana izongena kwimigomo esebenzayo, izinhlobo kanye nokusetshenziswa kwezimali ze-Fiber Optic Attenuators ezinhlelweni zokuxhumana ze-Optical.
I-Optical fiber attenuator, eyaziwa ngokuthi i-attenuator, isetshenziselwa ikakhulukazi ukuxazulula inkinga yamandla wesiginali ngokweqile okubangelwa ukudluliswa okude kwe-fiber okude.Ukuze ulingisa ngokunembile ukulahleka kokukhanya kwesikhathi eside futhi uthuthukise ukusebenza kohlelo, ukusetshenziswa kwabathakathi kubaluleke kakhulu.Inganciphisa ngempumelelo isilinganiso sephutha lephutha (i-BER) futhi iqinisekise ukuqina kokudluliselwa kwesiginali ngokulungisa amandla okubona ngesikhathi sokudluliselwa.Ikakhulu lapho i-transmitical transmitic kanye nemodyuli etholayo isondelene, kusetshenziswa i-attenuator kungagwema ukucekelwa phansi kwekhwalithi okubangelwa amandla ngokweqile.
Isebenza kanjani i-Optic Optic Optic
Umgomo osebenzayo we-Fiber Optic Acticotors angafaniswa nezibuko.NjengamaSunglasse amunca ukukhanya kwelanga ukuze avikele amehlo akho, abalandeli be-fiber optic baqinisekisa ukuthi amasiginali we-optical adluliselwa emandleni afanele ngokuthola amandla okukhanya ngokweqile.Ama-attenuators asezingeni eliphakeme we-fiber optic optic afinyelela imiphumela ye-attinuation ngokuthola amandla kunokuba abonise amandla akhanyayo.Lokhu kubaluleke kakhulu ekuxhumaneni kwe-Fiber Optic ngoba kudinga ukusetshenziswa kwamandla aphansi aphezulu ukuqeda ukudluliswa kwesiginali ngaphandle kokulimaza i-actonuator uqobo.
Ukuhlukaniswa kwama-actenuators we-fiber optic kanye nezicelo zawo
I-Optical fiber actonuators ihlukaniswe ngezinhlobo ezimbili: ihleliwe futhi iyashintshwa, ngalinye lilungele izimo ezihlukile zohlelo lokusebenza.
Ama-actenuators we-fiber optic optic, njengoba igama labo libonisa, linamanani we-attinuation asethwe esikhundleni futhi asetshenziswa kabanzi kumanethiwekhi okuxhumana ngocingo, imishini yokuhlola ye-fiber optic, amanethiwekhi endawo yendawo (amanethiwekhi wendawo (amanethiwekhi wendawo (amanethiwekhi wendawo (amanethiwekhi wendawo (amanethiwekhi wendawo (amanethiwekhi wendawo (amanethiwekhi wendawo.Lolu hlobo lwe-attenuator luhlangabezana nezidingo ezithile zamandla wesiginali ngokunikeza inani elinqunyelwe le-attenciation (ngokwesibonelo, -3DB kusho ukunciphisa amandla okukhanya ngo-50%).Ukusebenza kwayo ikakhulukazi kuya ngohlobo lokufaka kanye nokwakhiwa kwesixhumi, futhi kuklanyelwe ukuhambisana nezixhumi ezahlukahlukene ze-fiber optic (njenge-FC, ST, SC ne-LC) ukufezekisa ukuthunyelwa kwenethiwekhi kanye nokugcinwa.
Abahlinzeki be-Fibrieble abaguqukayo bahlinzeka ngokuguquguquka okuphezulu futhi balungele ukuguqula okuguqukayo kwezidingo zamandla aphezulu, njengokuhlola nokulinganisa ama-amplifiers (Edfa), kanye nokulinganisa amandla okubona phakathi kweziteshi ezahlukene.Lolu hlobo lwe-actenuator lusebenzisa umklamo okhethekile futhi lungashintsha inani le-atchanuation ngokuya ngezidingo zangempela ukuze uzuze umphumela omuhle kakhulu wokuxhumana.Imodi yayo yokusebenza ifaka ukusebenzisa izinguquko ze-Index zokushintsha kwezinto zangaphandle ezihlukile ukufezekisa ukulawulwa okuqondile kwamandla okubona ngokusebenzisa imiphumela ye-thermo-optical, e-electro-optical noma imiphumela ye-acousto-optical.
