Imojula yokubona iqukethe ingxenye ye-photoelectronic, isifunda esisebenzayo, nesixhumi esibonakalayo esibonakalayo.Ingxenye ye-photoelectronic iqukethe izingxenye ezidlulisayo nokwamukelayo.
Ukukubeka kalula, umsebenzi we-optical module ukuguqulwa kwe-photoelectric.Isiphetho sokuthumela siguqula amasignali kagesi abe amasignali optical, futhi isiphetho sokwamukela siguqula amasignali okubonayo abe amasignali kagesi ngemva kokudluliselwa ngamafiber optical.
Imodi eyodwa imelelwa i-SM, ilungele ukudluliswa kwebanga elide, kuyilapho i-multi-mode imelwe i-MM, ifanele ukudluliselwa kwebanga elifushane.Ubude begagasi obusebenzayo bemojula ye-multi-mode optical module ngu-850nm, kanye nemodyuli yemodi eyodwa ye-optical module. ingu-1310nm kanye ne-1550nm.
Amamojula e-single-mode optical asetshenziselwa ukudluliswa kwebanga elide, nebanga lokudlulisela lifinyelela ku-150 kuya ku-200km. Amamojula optical mode-multi-mode asetshenziselwa ukudluliswa kwebanga elifushane, nebanga lokudlulisela elifika ku-5km.I-single-mode optical modules isetshenziselwa ukudluliswa kwebanga elide, nebanga lokudlulisela lifinyelela ku-150 kuya ku-200km. Amamojula we-multi-mode optical asetshenziselwa ukudluliswa kwebanga elifushane, nebanga lokudlulisela lifika ku-5km.
Umthombo wokukhanya we-multi-mode optical module yi-diode ekhipha ukukhanya noma i-laser, kuyilapho umthombo wokukhanya wemodyuli yemodi eyodwa i-LD noma i-LED enomugqa omncane we-spectral.
Amamojula we-Multi-mode optical asetshenziswa kakhulu ekudluliselweni kwebanga elifushane, njenge-SR.Kunamanodi amaningi nezixhumi kulolu hlobo lwenethiwekhi.Ngakho-ke, amamojula we-multi-mode optical anganciphisa izindleko.
Amamojula abonakalayo emodi eyodwa asetshenziswa kakhulu kolayini abanamazinga aphezulu okudlulisela, njenge-MAN (inethiwekhi yendawo yeMetropoliitan)
Ukwengeza, amadivaysi emodi eminingi angasebenza kuphela ngempumelelo kumafayibha emodi eminingi, kuyilapho amadivaysi emodi eyodwa angasebenza ngokuphumelelayo kuzo zombili izintambo zemodi eyodwa kanye nemodi eminingi.
Imojuli yokubona yemodi eyodwa isebenzisa izingxenye eziningi eziphindwe kabili njengemojula yemodi yokubona eminingi.Ngakho-ke, izindleko eziphelele zemodyuli ye-single-mode optical ziphakeme kakhulu kune-multi-mode optical module.
Imojuli yezinga eliphezulu yokubona ayikwazi ukusetshenziswa njengemojula yezinga eliphansi lokubuka.I-high-rate optical module ingasetshenziswa njengemojula yezinga eliphansi le-optical.Nakuba amanye amamojula optical ehambisana namanye amamojula optical, amanye awahambisani.
I-laser ekhishwe yi-single-mode optical module ingangena yonke i-fiber optical, kodwa ku-fiber optical iyi-transmission ye-multi-mode, ukuhlakazeka kukhulu kakhulu, ukuhanjiswa kwebanga elifushane kulungile.Nokho, njengamandla optical okuphela kokuthola. ukwanda, amandla okubona okuphela kokwamukela angase alayishwe ngokweqile.Ngakho-ke, uyelulekwa ukuthi usebenzise imicu ye-optical yemodi eyodwa esikhundleni semicu yemodi eminingi yamamojula wemodi eyodwa.
Amamojula okubona kufanele asetshenziswe kumodi yontanga.Isibonelo, izinga lokudlulisela, ibanga lokudlulisela, imodi yokudlulisela, kanye nobude beza beza obusebenzayo bamamojula okubona ezindaweni zokuthumela nokwamukela kumele kufane.Ukucaciswa kwesixhumi esibonakalayo samamojula we-optical anamabanga ahlukene wokudlulisa ahluka kakhulu, futhi amamojula optical anamabanga amade okudlulisela anamanani aphezulu.Ukuxhumanisa kungenziwa ngokufanisa ukuncishiswa kwe-optical okufanelekile ngokusho kwesimo sangempela senethiwekhi.
Lapho amandla okuthumela optical ekupheleni kontanga mkhulu kunomkhawulo ongaphezulu wamandla optical atholayo we-module optical yasendaweni, udinga ukuxhuma i-optical attenuate isignali ye-optical kusixhumanisi, bese uxhuma i-module optical yendawo.Ibanga elide. imojuli ye-optical Kuzinhlelo zokusebenza zebanga elifushane, sebenzisa i-optical attenuation, ikakhulukazi izinhlelo zokusebenza ezizihambelayo, ukugwema ukushisa imojuli yokubona.
