I-Optical transceiver

Ama-transceivers optical, abantu abaningi abakaze bezwe ngawo, okungukuthi, abanye abantu abayizwile abazi ukuthi kuyini. Eqinisweni, i-transceiver ebonakalayo iyisisetshenziswa esibulalayo sokudlulisa isignali ye-optical. Kalula nje, i-transceiver ebonakalayo iyisiguquli sesignali, esilungiselelwe ekuqaleni kanye nesiphetho. Isiphetho sokuqala siguqula isignali kagesi ibe isignali yokubona, futhi itheminali iguqula isignali yokubona ibe isignali kagesi, okuyi-transceiver ebonakalayo. Ngakho-ke nazi izingxenye ezintathu: isiphetho sokuqala (i-optical transmitter), i-transmission medium, kanye ne-terminal (i-optical receiver). Kodwa-ke, i-transceiver ebonakalayo yenza ukuguqulwa kwesignali njalo. Uyini umsebenzi wayo?

Njengoba sonke sazi, ijubane lokusabalalisa ukukhanya lishesha kakhulu. Lokhu kusebenza kahle kokudlulisela phambili kuzoqinisekisa ukusebenza kahle nokufika ngesikhathi kweminye yemisebenzi yethu, njengokubhekwa kwevidiyo. Izimpawu ezijwayelekile azikwazi ukuthwala ukusabalala okusheshayo kwedatha enkulu, futhi ukuqapha ngesikhathi sangempela kwevidiyo kufanele kuqinisekise ukuthi isithombe sifika ngesikhathi futhi sibushelelezi, okuholela ekuchazeni okuphezulu. Kodwa-ke, akukho khamera noma isiqaphasi sekhompyutha esingakwazi ukukhiqiza noma ukwamukela amasignali ngokuqondile, ngakho-ke inani lesicelo le-transceiver ebonakalayo liyaboniswa.

Kuhle ukusho ukuthi i-transceiver optical ihlukaniswe ngama-analog optical transceivers kanye nama-digital optical transceivers, abizwa nangokuthi ama-transceiver optical video.

I-analog optical transceiver idinga ukwenza i-amplitude noma i-frequency modulation kusiginali ukuze iguqule isignali kagesi ibe isignali yokubona, futhi ithole isignali yokubona kutheminali, futhi idinga ukwenza ukwehla ukuze kubuyiselwe idatha nolwazi lwesithombe.

I-digital optical transceiver isebenzisa inombolo efana no-0, 1 ukucubungula idatha, izithombe, njll., ihlanganisela amasignali amaningi anesivinini esiphansi, bese iwaguqulela amasignali abonakalayo, futhi ibuyisela amasignali okubona kumasignali amaningi anesivinini esincane. kutheminali, bese ekugcineni iziguqule zibe yividiyo. , izithombe, idatha, njll.
