I-analog optical transceiver iwuhlobo lwe-optical transceiver, ethatha ngokuyinhloko i-analog frequency modulation, amplitude modulation, kanye ne-modulation yesigaba ukuze kulungiswe ividiyo ye-baseband, umsindo, idatha nezinye izimpawu kumvamisa ethile yenkampani yenethiwekhi, futhi iyidlulisele nge-transmitter optical transceiver. . Isignali ye-optical transmitted: Isignali ye-optical ekhishwe yi-analog optical transceiver iyisiginali ye-analog optical modulation, eshintsha i-amplitude, imvamisa, kanye nesigaba sesiginali ye-optical nge-amplitude, imvamisa, kanye nesigaba sesignali ye-analog yenkampani yenethiwekhi yokufaka. Ngakho-ke, yini i-analog optical transceiver? Yiziphi izinzuzo kanye nokubi kwama-analog optical transceivers? Sicela ulandeleI-JHA TECHukuze ufunde mayelana ne-analog optical transceiver.

I-analog optical transceiver isebenzisa ubuchwepheshe bokushintshashintsha be-PFM ukuze idlulise amasiginali wesithombe ngesikhathi sangempela. Isiphetho sokudlulisa senza ukushintshashintsha kwe-PFM kusiginali yevidiyo ye-analogi, bese senza ukuguqulwa kwe-electrical-optical. Ngemuva kokuthi isignali yokubona idluliselwe ekugcineni kokwamukela, yenza ukuguqulwa kwe-photoelectric, bese yenza ukwehlisa i-PFM ukubuyisela isignali yevidiyo. Ngenxa yokusetshenziswa kobuchwepheshe bokushintshwa kwe-PFM, ibanga layo lokudlulisela lingafinyelela ku-50Km noma ngaphezulu. Ngokusetshenziswa kobuchwepheshe be-wavelength division multiplexing, ukudluliswa kwezimpawu ezimbili zesithombe nedatha kungabuye kubonakale ku-fiber optical eyodwa ukuze kuhlangatshezwane nezidingo zangempela zamaphrojekthi wokuqapha.
