Ekusebenziseni ukusetyenziswa kweemodyuli ze-optical, akunakuphepheka ukuhlangabezana neengxaki ezahlukeneyo. Ukuze kuncitshiswe ingxaki yokungaphumeleli, kodwa nokukhusela uzinzo lwemodyuli ye-optical ngokusebenzisa. Kuya kubakho imisebenzi yobhaqo eyahlukeneyo yeemodyuli ezibonakalayo. Imodyuli ye-1X9 yeyona nto iphambili...

Imveliso ye-optical power (Amandla okuPhuma) ibhekiselele kumyinge wemveliso ye-optical power yomthombo wokukhanya ekupheleni kokuthumela imodyuli ye-optical, ekwabizwa ngokuba yi-output optical power, enokuqondwa njengobunzulu bokukhanya. Ifomula: P(dBm)=10Log(P/1mW) Iyunithi nguW okanye mW okanye dBm. (...

Oku kubhekiselele kujongano lwemodyuli ye-optical kwintambo yefiber optic patch, enokuthi idityaniswe ngemowudi enye okanye intambo yefiber optic yemultimode. Oku kulandelayo kukuhlalutya oku ngokweendlela ezahlukeneyo zojongano. Okwangoku, olona nxibelelwano luphambili kwimarike zezi: MPO, LC, S...

Okwangoku, kukho iilaser zeFBG, FB kunye neDFB, Phakathi kwazo, ezona lasers zisetyenziswa ngokuqhelekileyo yiFP kunye neDFB. FBG: IFayibha Bragg Grating. I-FP: I-Fabry-Perot, i-Fabry-Perot ye-Laser Diode i-DFB: i-Fabry Feedback Laser, i-Feedback Feedback ye-Laser Diode ye-FB esetyenziswa ngokuqhelekileyo kunye ne-DFB. I-DFB ihlala...

Kweli nqaku ndiza kuthetha malunga nokuba yintoni ebangela ilahleko kuthumelo lwefiber optics. Masifunde… Isizathu sokuba kutheni i-optical fiber ithathe indawo yosasazo oluphakathi kunye nomgama omde lweentambo zothungelwano kungenxa yokuba usasazo lwefiber optical linelahleko ephantsi, kwaye ilahleko yalo yahlulwe kakhulu koku kulandelayo:...

(i) Ubude bombindi bobude obusebenzayo bemodyuli ye-optical eneneni luluhlu, kodwa kuya kubakho umahluko ocacileyo phakathi kwemowudi enye kunye nemowudi eninzi. Emva koko eli binzana lithiywa ngokubanzi ngokona bude buphakathi. Iyunithi yobude obuphakathi yinanometer (nm), ...
