Lokhu kubhekisela kusixhumi esibonakalayo semojula ye-optical kukhebuli ye-fiber optic patch, engaxhunywa ngemodi eyodwa noma intambo ye-fiber optic ye-multimode. Okulandelayo ukuhlaziya lokhu ngokusho kokusebenzelana okuhlukene. Njengamanje, izixhumanisi ezibonakalayo eziyinhloko emakethe yilezi: MPO, LC, S...

Njengamanje, kukhona amalaser e-FBG, FB kanye ne-DFB, Phakathi kwawo, amalaser asetshenziswa kakhulu yi-FP ne-DFB. I-FBG: I-Fiber Bragg Grating. I-FP: I-Fabry-Perot, i-Fabry-Perot I-Laser Diode DFB: I-Laser Yempendulo Esabalalisiwe, Impendulo Esabalalisiwe Ye-Laser Diode Ye-FB evame ukusetshenziswa kakhulu ne-DFB. I-DFB...

Kulesi sihloko ngizokhuluma ngokuthi yini edala ukulahleka kokudluliswa kwe-fiber optics. Masifunde… Isizathu sokuthi kungani i-optical fibre ingena esikhundleni sokudluliswa kwezintambo zenethiwekhi ebangeni eliphakathi nelide kungenxa yokuthi ukudluliswa kwe-fiber optical kunokulahlekelwa okuphansi, futhi ukulahleka kwayo kuhlukaniswe kakhulu kwaba okulandelayo:...

(i) Ubude begagasi obumaphakathi Ubude begagasi obusebenzayo bemojuli ye-optical empeleni buwububanzi, kodwa kuzoba nomehluko osobala phakathi kwemodi eyodwa kanye nemodi eminingi. Khona-ke lesi sisho ngokuvamile siqanjwa ngokuvumelana ne-wavelength emaphakathi kakhulu. Iyunithi ye-wavelength emaphakathi yi-nanometer (nm), ...

Ngokwezigaba ezihlukene zesikhathi sokuthuthukiswa: Amamojula optical ahlukaniswe abe izinhlobo ezimbili: amamojula e-PON optical kanye namamojula wendabuko optical. Uma usebenzisa amamojula wendabuko optical: Imodi yokudlulisa isignali ye-optical ikhomba-kuya-iphuzu (P2P: ukudluliselwa okukodwa kokukodwa), imojula...

Sawubona, Siyakwamukela. Masifunde ukuqhathanisa phakathi kwe-GPON kanye namamojula okukhanya we-EPON ngencazelo elula. I-GPON optical module inokusebenza okungcono kune-EPON optical module. Mayelana nesivinini, i-downlink ingcono kune-EPON; Mayelana nebhizinisi, i-GPON ihlanganisa ububanzi obubanzi; Kusukela ekudlulisweni...
