Imodyuli ye-optical iqukethe icandelo le-photoelectronic, isiphaluka esisebenzayo, kunye ne-interface ebonakalayo. Icandelo le-photoelectronic libandakanya ukuhambisa kunye nokwamkela iinxalenye.
Ukuyibeka ngokulula, umsebenzi wemodyuli ye-optical kukuguqulwa kwe-photoelectric. Isiphelo sokuthumela siguqula izibonakaliso zombane kwiimpawu ze-optical, kwaye isiphelo sokufumana siguqula izibonakaliso ze-optical zibe iimpawu zombane emva kokudluliselwa ngeefayili ze-optical.
Imodi enye imelwe yi-SM, ilungele ukuhanjiswa komgama omde, ngelixa i-multi-mode imelwe yi-MM, ifanelekile ukuhanjiswa komgama omncinci. yi-1310nm kunye ne-1550nm.
Iimodyuli ze-optical mode enye zisetyenziselwa ukuhanjiswa komgama omde, kunye nomgama wokuhambisa ufikelela kwi-150 ukuya kwi-200km. ukuhanjiswa komgama omde, kunye nomgama wokudluliselwa ofikelela kwi-150 ukuya kwi-200km. Iimodyuli ze-Multi-mode optical zisetyenziselwa ukuhanjiswa komgama omfutshane, kunye nomgama wokuhambisa ukuya kwi-5km.
Umthombo wokukhanya wemodyuli ye-multi-mode optical i-diode ekhupha ukukhanya okanye i-laser, ngelixa umthombo wokukhanya wemodyuli ye-single-mode optical i-LD okanye i-LED enomgca omncinci we-spectral.
Iimodyuli ze-Multi-mode optical zisetyenziselwa ikakhulu ukuhanjiswa komgama omfutshane, njenge-SR. Kukho iindawo ezininzi kunye nezihlanganisi kolu hlobo lothungelwano. Ngoko ke, iimodyuli ezininzi ze-optical mode zinganciphisa iindleko.
Iimodyuli ze-optical mode enye zisetyenziswa kakhulu kwimigca enezinga eliphezulu losulelo, njenge-MAN (inethiwekhi yendawo ye-Metropoliitan)
Ukongeza, izixhobo zeendlela ezininzi zinokusebenza kuphela ngokufanelekileyo kwiifiber ezininzi, ngelixa izixhobo zemowudi enye zinokusebenza ngokufanelekileyo kuzo zombini iifiber zemowudi enye kunye neendlela ezininzi.
Imodyuli ye-optical mode enye isebenzisa amacandelo amaninzi aphindwe kabini njengemodyuli ye-optical mode. Ngoko ke, ixabiso elipheleleyo lemodyuli ye-optical mode enye iphezulu kakhulu kunemodyuli ye-multi-mode optical.
Imodyuli ephezulu yezinga eliphezulu ayinakusetyenziswa njengemodyuli ye-optical ephantsi. Imodyuli ye-optical high-rate inokusetyenziswa njengemodyuli ye-optical ephantsi. Nangona ezinye iimodyuli ezibonakalayo zihambelana nezinye iimodyuli ze-optical, ezinye azihambelani.
I-laser ekhutshwe yimodyuli ye-single-mode optical ingangena yonke i-fiber optical, kodwa kwi-fiber optical yi-multi-mode transmission, i-dispersion inkulu kakhulu, ukuhanjiswa komgama omfutshane kulungile. ukwanda, amandla optical of the end of receiveing can be overloaded. Ke ngoko, uyacetyiswa ukuba usebenzise iifiber ze-optical mode enye endaweni ye-multi-mode optical fibers kwiimodyuli zemodyuli enye.
Iimodyuli zamehlo kufuneka zisetyenziswe kwimowudi yoontanga. Ngokomzekelo, izinga lokudluliselwa, umgama wothumelo, imodi yokuhambisa, kunye nobude bokusebenza kweemodyuli ze-optical ekuthumeleni nasekufumaneni iziphelo kufuneka zifane. Ukucaciswa kwe-Interface yeemodyuli ze-optical kunye nemigama ehlukeneyo yokudlulisa iyahluka kakhulu, kwaye iimodyuli ze-optical ezinemigama emide yokuhambisa zinexabiso eliphezulu.
Xa uthumela amandla optical optical end of peer end mkhulu kunomda ophezulu wokufumana amandla optical wemodyuli yendawo yendawo, kufuneka udibanise i-optical attenuate uphawu lwe-optical kwikhonkco, uze udibanise imodyuli yendawo yendawo.Umgama omde. imodyuli yokubona Ukusetyenziswa komgama omfutshane, sebenzisa i-optical attenuation, ngakumbi kwi-self-loop applications, ukunqanda ukutshisa imodyuli yokubona.
