    Isetshenziselwa ini imojuli ye-optical?

    Isikhathi sokuthumela: Dec-07-2022

    Imojula yokubona iyidivayisi yokuguqula isignali yesithombe, engafakwa kumishini yokudlulisa isignali yenethiwekhi njengeimizila, amaswishi, kanye nemishini yokudlulisa. Kokubili amasignali kagesi kanye ne-optical amasignali amaza kazibuthe. Uhla lokudluliswa kwezimpawu zikagesi lunqunyelwe, kuyilapho amasignali optical angadluliselwa ngokushesha nakude. Kodwa-ke, amanye amadivaysi amanje abona amasignali kagesi, ngakho-ke kukhona amamojula okuguqula ama-photoelectric.

    i-optical module(1)

    Ngenxa yomkhawulokudonsa ophezulu kanye nebanga elide lokudlulisela lokudluliswa kwe-fiber optical, kuyilapho ibanga lokudluliswa kwekhebula elivamile lifushane futhi lingenwa ukuphazanyiswa yi-electromagnetic, ukuze kunwetshwe ibanga lokudlulisela lokuxhumana, i-optical fiber isetshenziselwa ukudlulisa. Ngokubamba iqhaza kwamamojula we-optical, amasignali kagesi angaguqulwa abe amasignali optical ukuze adluliselwe kuma-optical fibers, bese aguqulwa kusukela kumasignali optical abe amasignali kagesi azotholwa imishini yenethiwekhi, ngaleyo ndlela andise ibanga lokudlulisela ukuxhumana kwedijithali.
    Umgomo wokusebenza wemojula ye-optical ekupheleni kokudlulisa uwukufaka isignali kagesi ngenani elithile lekhodi ngokusebenzisa itheminali yomunwe wegolide, bese ushayela i-laser ukuthumela isignali yokubona ngenani elihambisanayo ngemva kokucubungula i-chip yomshayeli. ;
    Umgomo wokusebenza ekugcineni ukuguqula isignali ye-optical eyamukelwe ibe isignali kagesi ngomtshina, bese uguqula isignali yamanje ebuthakathaka eyamukelwe ibe isignali ye-voltage nge-transimpedance amplifier, ngaleyo ndlela ikhulise isignali kagesi, bese ususa u-overvoltage. isignali nge-amplifier ekhawulela. Isignali kagesi ephezulu noma ephansi igcina isignali kagesi ephumayo izinzile.
