Yethuilizweiitransceiver zefowuni zamehloziphuhliswe ngokukhawuleza ngophuhliso lweshishini lokubeka iliso.Ukusuka kwi-analog ukuya kwidijithali, kwaye emva koko ukusuka kwidijithali ukuya kwi-high-definition, bahlala beqhubela phambili.Emva kweminyaka yokuqokelelwa kobugcisa, baye bakhula bafikelela kwinqanaba eliqolileyo kakhulu.Ii-transceivers ze-telephone optical azizange zenze impumelelo enkulu kwitekhnoloji, kodwa eminye imisebenzi ekhethekileyo isenokuphuhliswa kwaye igqitywe kwizicelo ezahlulahlulwe.Kubandakanya ukuphuculwa komsebenzi oqhelekileyo onjengozinzo lwenkqubo kunye nomthamo, oku kukwabangela ukuba abavelisi be-transceiver optical befowuni bangadinwa bafune impumelelo.

Akukho mda kuphuhliso kunye nezinto ezintsha, kwaye ukuzinzisa ukusebenza yeyona nto iphambili.Xa itekhnoloji yee-transceivers optical for phones ivuthiwe, abaninzi abavelisi bajika bajolise ekuphuhliseni imveliso yabo.Okwangoku, ukusebenza kwee-transceivers optical kuphuculwe ikakhulu kula manqaku alandelayo:

Eyokuqala kuphuhliso lwendlela enye.I-fiber optical inokwahlulwa ibe yi-multi-mode kunye ne-single-mode ngokuhambisa ukukhanya kuyo.Imowudi enye inokuphepha ngokupheleleyo ukusasazwa kwemodal, kwaye inesiphumo esihle sothumelo, ayiphazamiseki lula, kwaye inomthamo omkhulu wokuhanjiswa kwamaza kunye nomthamo omkhulu wothumelo.Lungelelanisa umthamo omkhulu, usasazo lomgama omde.

Okwesibini luyilo lokufikelela kwiimodyuli kunye noluxutyiweyo.Uyilo lweemodyuli luguquguqukayo kwaye luyaguquguquka, olunokubonelela ngemisebenzi enokwandiswa kuphuhliso lwenkqubo;kunye nendlela yokwenza idijithali, ukudityaniswa kobuchwepheshe be-SDI, kunye nokuhlalisana kweemveliso ezisemgangathweni ezahlukeneyo kuzisa ukuphazamiseka kubavelisi.Ngoko ke, .Ukongeza kuyilo lwemodyuli, uyilo lokufikelela kwi-hybrid nalo luyafuneka, ukubonelela nge-interface ye-RJ-45 yenethiwekhi, ujongano lwe-BNC, njl njl kwisixhobo, ukwenzela ukuba zombini izibonakaliso ze-analog kunye neempawu zenethiwekhi zinokudluliselwa kwi-transceiver efanayo.

Okwesithathu kukutyebisa iifom zezicelo zee-phone transceivers optical transceivers.Le teknoloji iya kunciphisa kakhulu inani leemveliso kwiinkcukacha enye okanye ezimbini, kwaye abathengi banokufikelela kubo ngokuthanda.Ngokwemeko yendawo yokufikelela kwi-fiber optical, kukulungele ukucwangcisa, kwaye i-transceiver optical yefowuni ayisayi kuphinda ikhawulelwe yi-point-to-point, i-node, i-ring, aggregation, njl. Enye imveliso ihambelana nazo zonke iindlela zokufikelela. , ukunciphisa kakhulu inani lemicu ye-optical esetyenziswayo.

Okwesine kukusetyenziswa kweteknoloji ye-multiplexing (ixesha eliqhelekileyo le-EDM, i-TDM, kunye ne-WDM), eyona nto isombulula ingxaki yomthamo omncinci wokuhambisa i-fiber enye, ngakumbi ukusetyenziswa kwe-HD-SDI, ethatha i-bandwidth enkulu kwaye ine-. umthamo omkhulu weshishini.Ukuba iteknoloji ye-multiplexing kunye ne-wavelength division multiplexing iteknoloji inokudityaniswa, umthamo unokuphucula amaxesha amaninzi.Ke ngoko, uphando kunye nophuhliso lwetekhnoloji yokuphindaphinda kubaluleke kakhulu.
