Ngendaba ya- to Ukuxhumana kwe-Optical, ukulawulwa kwamandla kufakazela ukuthi kuyindlela ebalulekile uma kuziwa ekuqineni kanye nobungcweti bamasiginali esizindeni sabo esihlosiwe. Ngokwenyuka kwesidingo sejubane namandla okuxhumana namanethiwekhi okuxhumana, kunesidingo sangempela sokuphatha amandla ezimpawu zokukhanya ezidluliselwa nge-fiber Optics ngempumelelo. Lokhu kuholele ekudalweni kwe Ama-Optic Optic Optic njengesidingo sokusetshenziswa kwimicu. Banesicelo esibucayi ekwenzeni njenge-actonuators ngaleyo ndlela bavimbela amandla ezimpawu zokubona ukuthi zibe nzima ukulimala kwemishini yokuthola noma ngisho namaphethini wesiginali asontekile.
I-fiber attenuation okuyisisekelo esiyisisekelo esivumelwaneni se-fiber optic singachazwa njengokulahleka okutholwe kumandla wesiginali asesimweni sokukhanya njengoba kudlula kukho Intambo ye-fiber optic. Le attenuation ingenzeka ngenxa yezizathu ezahlukahlukene ezihlanganisa ukusakazwa, ukudonsa, nokulahleka kokugoba. Yize i-adtonuation yesiginali iyijwayelekile impela akufanele ifinyelele amazinga abi kakhulu njengoba kulimaza ukusebenza kahle kwezinhlelo zokuxhumana. Ukuxazulula le nkinga, asetshenziswa ama-actorutors emdlalweni wokunciphisa ukuqina kwesiginali ezingeni lokusetshenziswa kwalo okusebenzayo kanye nomthelela omncane kwisikhathi sokuphila kwenethiwekhi.
Ku Uhlelo lokuxhumana lwe-Optical, isiginali kumele ibe sezingeni elithile lamandla adingeka owemukelayo ukucubungula isinali. Uma isinali liqukethe amandla aphezulu, bese lilayisha umuntu owemukelayo futhi kwesinye isikhathi liholela emaphutheni, futhi uma isinali lithwala amandla aphansi, khona-ke owemukelayo kungenzeka angakwazi ukuthola isibonakaliso kahle.Ama-Optic Optic OpticDlala indima ephambili ekulondolozeni imali esele ikakhulukazi lapho amabanga amade avela emazingeni aphezulu anamandla angaba ngumsindo wokuphela kokuthola.
Kunezigaba ezimbili ze-Fiber Optic Attenuators, ngalinye lahlukaniswa ukwakhiwa kwalo kanye nomsebenzi: Abalandeli abahleliwe kanye nabathengisi abahlukahlukene. Ama-actenuators we-fiber optic atholakala emiklamo ehlukene nezinhlobo, futhi ngamunye wabo kufanelekile ukusetshenziswa noma isidingo esithile. Ama-actonuators alungisiwe ayi-actonuators yendawo yonke ngenkathi abebekhona abaguquguqukayo bangabahlinzeki abathile.
Ama-Actenuators ahleliwe: Lezi yizinto ezilandelwayo ezinikela ngenani elijwayelekile le-atchation futhi zivame ukusetshenziswa ezimweni, lapho kutholakala khona izinga elingaguquki le-attemiation. Ama-actonuators alungisiwe atholakala ngokujwayelekile amazinga athile athathayo, okuhlukahlukene okungahlukahluka kusuka ku-DB embalwa kuze kube amashumi e-DB. Inzuzo eyinhloko yalezi zinhlobo zemiculi ukuzilula ukusetshenziswa kwazo kanye nokufakwa ezinhlelweni ezahlukahlukene zokuxhumana ze-Optical zokuxhumana.
Ama-Actenuators aguqukayo: Ngakolunye uhlangothi, abahlinzeki abahlukahlukene bavumela inkululeko yokushintshanisa inani le-attenciation elisetshenziswa ngenxa yemvelo yayo ehlukahlukene ekwakhiweni kwe-actetuator design. Lokhu kulungiswa kungaba yincwadi ephelele noma kungavuselelwa ukusetshenziswa kwezilawuli ze-elekthronikhi. Izilungiselelo eziguquguqukayo zingaqashwa kumasethingi wamandla esinari aguquguqukayo lapho kungafika amasignali ngamandla ahlukile ngezikhathi ezihlukile ngakho-ke lapho amandla awo angadinga ukulungiswa ngezikhathi ezithile. Zitholakala ekuhlolweni okuningi nasezilinganiso lapho amasiginali ehluka futhi ahluka khona.
I-Fibre Optic AttenuatorKulesi simo, nokho, kusho isengezo eklanywe ngenhloso efanayo yokufaka ukukhanya ngezinga elinqunyelwe kusengaphambili. Ngamanye amagama, lokhu kungenziwa ngezinqubo ezifana ne-adsorption, ukungafani, kanye nokuboniswa. Bobathathu banezinzuzo zabo futhi zikhethwe ngokuya ngokucaciswa kohlelo lokusebenza olusetshenziswayo.
Abathengisi abanokuzithoba: Lezi zakhiwo zifaka izinto ezicwilisa ngempumelelo 'ingxenye yesiginali ye-Optical futhi uyivimbele ekubeni namandla kangaka. Enye yezinto ezicatshangelwe kakhulu lapho kukhulisa ama-acterecators asuselwa kunqubo yokusebenza yokuzithoba kungukukhethwa kwezinto ezibonakalayo kanye nesakhiwo ukuze lokhu kuzonikela nge-attenciation ecishe ibe khona.
Ukusakaza Abathengisi: Abakwa-Actenoutors abasezingeni eliphansi abasakazwayo basebenza ngomgomo wokulahleka ngamabomu ngamabomu ngendlela yokuhlanekezela kwendawo ku-fiber ukuze ukukhanya kwesigameko kuhlasela udonga oluyinhloko futhi kuhlakazwa ngaphandle kwefayibha futhi kuhlakazeke ngaphandle kwefayibha futhi kusatshalaliswa ngaphandle kwefayibha futhi kuhlakazeke ngaphandle kwefayibha futhi kusatshalaliswa ku-fiber. Ngenxa yalokhu, lo mphumela wokuhlakazeka uholela ekubuthakathaka kwesiginali ngaphandle kokuyekethisa amandla omdabu wefayibha. Idizayini kufanele iqinisekise ukusatshalaliswa kanye namaphethini we-puf alindelekile ukuze afinyelele amazinga adingekayo atholakalayo.
Ama-actenuators abonakalayo: Abathengisi abakhombisa basebenza ngomgomo wempendulo, lapho ingxenye yesiginali yokukhanya isebuyiselwe emuva emthonjeni, ngaleyo ndlela inciphisa ukudluliselwa kwesiginali lapho kulungiswa khona. Lezi zakhiwo zingafaka phakathi izingxenye ezibonisa okufana nezibuko ngaphakathi kwendlela yokubona noma ukubekwa kwezibuko endleleni. Isakhiwo sohlelo kumele senziwe ngendlela yokuthi ukuboniswa kuphazamise uhlelo ngendlela yokuthi ikhwalithi yesiginali ithinteke.
I-Fibre Optic Attenuators yimikhiqizo ebalulekile yezinhlelo zesimanje zokuxhumana, abaqambi kufanele bakhethe ngokucophelela. Ngokulawulwa kwezimpawu zamandla, la magajethi aqinisekisa ukuhamba okuphephile nokusebenzayo kwedatha ngaphakathi kwenethiwekhi. Ekuhlakazeni, i-attenuation ye-fiber ingukuwohloka kwesiginali esenzeka ibanga elinikezwe ngenxa yokuboniswa kwesiginali, ukuphazamiseka, kanye nokuhlakazeka. Ukubhekana nale nkinga, kunezinhlobo ezahlukene ze-acticoutors ezingase zikwazi ukungonjiniyela futhi zizisebenzise. Ekuthuthukisweni kobuchwepheshe bokuxhumana kwe-Optical Communication, umuntu ngeke akwazi ukukushaya ngempumelelo kokusebenza kwezinto ezisetshenziswayo ze-fiber optic njengoba amadivaysi okuthepha nokuklama azohlala efanelekile ekuxhumaneni kwalawa mapulatifomu amancane.
