Ama-transceivers optical nawo ayimishini yokudlulisa isignali ye-optical. Ama-transceivers optical angaphandle anobuchwepheshe obuvuthiwe kodwa ayabiza. Nakuba ama-transceivers optical asekhaya engavuthiwe kangako kwezobuchwepheshe, awabizi ngokwanele ukubhekana nangaphakathi. Khona-ke yikuphi ukukhethwa kwama-transceivers optical?

Izinyathelo zokuqapha zokuthenga ama-transceivers optical: Kusukela kusignali ethunyelwe ku-fiber optical, ama-transceivers optical angahlukaniswa abe ama-analog optical transceivers ngokusekelwe kubuchwepheshe be-analog kanye ne-digital optical transceivers ngokusekelwe kubuchwepheshe bedijithali. Umgomo wokusebenza we-analog optical transceiver awuyona into edlula ukumodulation kanye nokwehliswa, ukuhlunga nokuxuba isignali, njll. Kungakhathaliseki ukuthi i-LED noma i-LD, izici zayo zokumodareyitha kwezithombe azikona umugqa. Enqubweni yokudlulisa isignali, ukuhlanekezela, ukuphazamiseka kanye nezinye izinkinga ezingenakugwemeka ekucubunguleni i-analog akunakugwenywa, futhi kukhona nobuchwepheshe obungenakunqotshwa ekudluliseni umthamo omkhulu kanye nokudluliselwa okuxubile kwezinsizakalo eziningi. ubunzima.

Isimo sama-digital optical transceivers sihlukile. Kunezifunda ezimbili kuphela "zefayibha kanye "no-fiber" ku-fiber optical. Ngakho-ke, i-linearity yomthombo wokukhanya ayiphezulu noma cishe ayikho imfuneko, ngaleyo ndlela igwema ukulahlekelwa kwesignali enqubweni yokucubungula. Ngaphezu kwalokho, ama-transceivers optical digital alula ukufeza ukudluliselwa kweziteshi eziningi nokuxubile kwamasignali amaningi. Njengoba ziguqulwa kuphela zibe izimpawu zedijithali, ukudluliswa kwamashaneli amaningi namasignali amaningi kungenziwa kalula ngosizo lobuchwepheshe be-TDM (Time Division Multiplexing). Abakhiqizi abakhona be-transceiver optical bangadlulisela izithombe zevidiyo zesikhathi sangempela ezingacindezelwe eziyi-10 esiteshini esisodwa sobude beza ngesikhathi.

I-topology yenethiwekhi ye-fiber optical, i-optical fiber network topology inquma uhlobo lwe-transceiver optical yevidiyo. Ngokusho kwe-topology yenethiwekhi yokudlulisa i-fiber optical, ngaphezu kwama-transceivers optical wendabuko we-point-to-point, kukhona futhi ama-transceivers optical optical wenethiwekhi yendandatho ongakhetha kuwo. I-transceiver yevidiyo ye-node yohlobo lwe-node ihlanganisa izindawo ezingaphambili zibe yinethiwekhi yeketanga noma inethiwekhi yesihlahla. Umshini we-node kuqala uthola isignali endaweni ngayinye, uyiguqule ibe isignali kagesi, bese ushintshanisa futhi uphindaphinde isignali ngenodi yendawo. Ngemuva kokuguqulwa kwe-photoelectric, ubuchwepheshe be-WDM busetshenziselwa ukuphindaphinda. Sebenzisa i-fiber optical ukuze udlulise. Akukho ukuguqulwa kwe-analog kuya kwedijithali okwenziwa endaweni ngayinye, okunciphisa ukuncishiswa kwesignali.

Isivinini sokudlulisa se-optical transceiver siyashesha, isikrini sicacile, futhi singasetshenziswa kuzo zonke izinhlobo zangaphandle. Inohlu olubanzi kakhulu lokusebenza futhi isetshenziswa kabanzi embonini.
