Ii-transceivers ze-Optical nazo zizixhobo zokuhambisa umqondiso we-optical. Iitransceivers zangaphandle zangaphandle zinetekhnoloji evuthiweyo kodwa zibiza kakhulu. Nangona ii-transceivers zasekhaya zasekhaya zingekavuthwa kangako kwitekhnoloji, azibizi ngokwaneleyo ukujongana nezo zangaphakathi. Emva koko yintoni ukhetho lwee-transceivers optical?

Izilumkiso zokuthenga i-transceivers optical: Ukusuka kwisignali ethunyelwe kwi-fiber optical, i-transceivers optical inokwahlulwa ibe yi-analog optical transceivers esekelwe kwi-analog technology kunye ne-digital optical transceivers esekelwe kwi-teknoloji yedijithali. Umgaqo osebenzayo we-analog optical transceiver akukho nto ngaphezu kokuguqulwa kunye nokuchithwa, ukucoca kunye nokuxuba umqondiso, njl. Ingaba i-LED okanye i-LD, iimpawu zayo ze-photoelectric modulation azikho mgca. Kwinkqubo yokuhambisa umqondiso, ukuphazamiseka, ukuphazamiseka kunye nezinye iingxaki ezingenakuphepheka ekuqhutyweni kwe-analog ayinakuphepheka, kwaye kukho iteknoloji engenakunqotshwa kwi-transmission enkulu kunye nokuhanjiswa kweenkonzo ezininzi. ubunzima.

Imeko ye-digital optical transceivers yahlukile. Kukho amazwe amabini kuphela "yefayibha kunye "nokungabikho kwefayibha" kwifiber optical. Ngoko ke, umgca womthombo wokukhanya awuphezulu okanye phantse akukho mfuneko, ngaloo ndlela ugwema ukulahleka komqondiso kwinkqubo yokucubungula. Ukongeza, i-digital optical transceivers kulula ukuphumeza i-multi-channel kunye nokuhanjiswa okuxubileyo kweempawu ezininzi. Ekubeni ziguqulwa kuphela kwiimpawu zedijithali, ukuhanjiswa kwamajelo amaninzi kunye neempawu ezininzi zinokuqondwa ngokulula ngoncedo lweteknoloji ye-TDM (i-Time Division Multiplexing). Abavelisi be-transceiver be-optical abakhoyo banokusasaza imifanekiso yevidiyo ye-10 engaxinzelelwanga ngexesha lokwenyani kwitshaneli ye-wavelength enye ngexesha.

I-Optical fiber network topology, i-optical fiber network topology imisela uhlobo lwe-video optical transceiver. Ngokwe-topology yothungelwano lwe-fiber optical network, ukongeza kwi-traditional point-to-point transceivers optical transceivers, kukho kwakhona uhlobo lwe-node kunye ne-ring network transceivers optical ukukhetha kuzo. I-node-type video optical transceiver idibanisa i-front-end nodes kwi-network chain okanye inethiwekhi yomthi. Umatshini we-node kuqala ufumana umqondiso kwi-node nganye, uyiguqule ibe ngumqondiso wombane, kwaye emva koko utshintshise kwaye uphindaphinda umqondiso nge-node yendawo. Emva kokuguqulwa kweefoto zombane, iteknoloji ye-WDM isetyenziselwa ukuphindaphinda. Sebenzisa i-fiber optical ukusasaza. Akukho kuguqulwa kwe-analog-to-digital kwenziwa kwindawo nganye, enciphisa ukuthotywa komqondiso.

Isantya sokuhanjiswa kwe-transceiver optical ikhawuleza, isikrini sicacile, kwaye sinokusetyenziswa kuzo zonke iintlobo zangaphandle. Inoluhlu olubanzi kakhulu lokusebenza kwaye isetyenziswa kakhulu kwishishini.
