Umehluko phakathi kwe-fiber optical engabonakali kanye ne-fiber optical evamile

Emkhakheni wezokuxhumana kanye nokudluliswa kwedatha, ubuchwepheshe be-fiber optic bushintshe indlela esixhumanisa futhi sixhumana ngayo. Phakathi kwezinhlobo ezahlukene ze-fiber optical, kuvele izigaba ezimbili ezivelele: i-fiber optical evamile kanye ne-fiber optical engabonakali. Nakuba inhloso eyisisekelo yazo zombili iwukudlulisa idatha ngokukhanya, izakhiwo zazo, izinhlelo zokusebenza, kanye nezici zokusebenza zihlukile kakhulu.

Ukuqonda i-fiber evamile

I-optical fiber ejwayelekile, evame ukubizwa ngokuthi i-standard fiber, yakhiwe i-core kanye ne-cladding. I-core yenziwe ngengilazi noma ngepulasitiki futhi isetshenziselwa ukudlulisa izimpawu zokukhanya. I-cladding ine-refractive index ephansi kune-core futhi ibuyisela ukukhanya emuva e-core, okuvumela ukuthi ihambe amabanga amade ngokulahlekelwa okuncane. I-optical fiber evamile isetshenziswa kabanzi kwezokuxhumana, ukuxhumana kwe-inthanethi, kanye nethelevishini yekhebula ukuhlinzeka ngokudluliselwa kwedatha okusheshayo emabangeni amade.

Isici esibalulekile sokuvamilei-fiber ebonakalayoukubonakala kwayo. Imicu ivame ukumbozwa esikhumbeni esivikelayo esingaba sobala noma esinombala ukuze sikwazi ukutholakala kalula. Lokhu kubonakala kunenzuzo ezindleleni eziningi zokusebenza ngoba kuvumela ukufakwa nokugcinwa okulula. Kodwa-ke, kungaba yinkinga futhi ezindaweni ezithile lapho ubuhle noma ukuphepha kuyinkinga.

Ukuvela kwefayibha engabonakali

Ngakolunye uhlangothi, imicu ye-optical engabonakali iyintsha kakhulu kwezobuchwepheshe be-optical. Njengoba igama lisho, le micu yenzelwe ukuba ingabonakali noma ingabonakali nhlobo emehlweni. Lokhu kufezwa ngamasu okukhiqiza athuthukile anciphisa ububanzi be-fiber futhi athuthukise izakhiwo zayo zokubuyisa. Imicu ye-optical engabonakali ivame ukusetshenziswa ezisetshenziswayo lapho ukuqonda kubalulekile khona, njengokukhanyisa kwezakhiwo, amadivayisi ezokwelapha, kanye ne-electronics yabathengi abasezingeni eliphezulu.

Inzuzo eyinhloko yemicu ye-optical engabonakali ubuhle bayo. Ngenxa yokuthi le micu ingahlanganiswa kalula ezindaweni ezahlukahlukene, ilungele ukusetshenziswa lapho imicu ye-optical yendabuko ingaba yinto ephazamisayo. Isibonelo, ezakhiweni zesimanje, imicu ye-optical engabonakali ingafakwa ezindongeni noma ophahleni ukuze inikeze ukukhanya ngaphandle kokuthinta ubuqotho bomklamo wesikhala.

Izici zokusebenza

Ngokuphathelene nokusebenza, kokubili okuvamilei-fiber ebonakalayokanye ne-optical fiber engabonakali inezinzuzo nezinkinga zayo. I-optical fiber ejwayelekile yaziwa ngomthamo wayo wokudlulisa idatha ophezulu kanye namakhono okuhamba ibanga elide. Iyakwazi ukudlulisa idatha eningi emabangeni amade ngokunciphisa isignali okuncane, okwenza ibe umgogodla wamanethiwekhi ezokuxhumana anamuhla.

I-fiber engabonakali, yize isasebenza kahle ekudlulisweni kwedatha, ingase ingafani ngaso sonke isikhathi ne-fiber evamile. Kodwa-ke, intuthuko kwezobuchwepheshe ithuthukisa njalo amakhono ayo. I-fiber engabonakali ingaklanywa ukuze isekele ukudluliswa kwedatha okusheshayo, okwenza ifanelekele izinhlelo zokusebenza ezithile lapho ubuhle nokusebenza kufanele kuhambisane khona.

Ekuphetheni

Ngamafuphi, umehluko phakathi kwe-fiber engabonakali nejwayelekile ulele kakhulu ekuboneni kwayo, ekusetshenzisweni kwayo, kanye nezici zokusebenza. I-fiber ejwayelekile isetshenziswa kabanzi kwezokuxhumana futhi iyabonakala kalula, kuyilapho i-fiber engabonakali inikeza ikhambi eliyimfihlo lezinhlelo zokusebenza lapho ubuhle bubalulekile khona. Njengoba ubuchwepheshe buqhubeka nokuguquka, zombili izinhlobo ze-fiber zizodlala indima ebalulekile ekwakheni ikusasa lokuxhumana nokuxhumana. Ukuqonda lokhu mehluko kungasiza abathengi kanye nemboni ukuthi benze izinqumo ezinolwazi mayelana nohlobo lwe-fiber olufanelana kahle nezidingo zabo.
