Eyethuizweama-transceiver optical ocingozithuthuke ngokushesha ngokuthuthukiswa kwemboni yokuqapha.Ukusuka ku-analog kuye kudijithali, bese kusuka kudijithali kuya ekuchazeni okuphezulu, ziqhubeka zithuthuka.Ngemva kweminyaka eminingi yokuqongelela ubuchwepheshe, baye bafinyelela esigabeni esivuthiwe kakhulu.Ama-transceiver optical ocingo awakenzi impumelelo enkulu kwezobuchwepheshe, kodwa eminye imisebenzi ekhethekile isengathuthukiswa futhi ipheleliswe ezinhlelweni ezihlukene.Kubandakanya ukuthuthukiswa kokusebenza okuvamile okufana nokuzinza kwesistimu namandla, lokhu futhi kungamandla ashayela abakhiqizi be-transceiver optical ocingweni ukuthi bafune ukuphumelela ngokungakhathali.

Awukho umkhawulo ekuthuthukisweni nasekusunguleni izinto ezintsha, futhi ukusimamisa ukusebenza kuyinto ehamba phambili.Lapho ubuchwepheshe bama-transceiver optical wezingcingo sebuvuthiwe impela, abakhiqizi abaningi baguqula ukugxila kwabo ekuthuthukisweni kube ngcono ukusebenza komkhiqizo.Njengamanje, ukusebenza kwama-transceiver optical kuthuthukiswa ikakhulukazi kulawa maphuzu alandelayo:

Okokuqala ukuthuthukiswa kwemodi eyodwa.I-fiber optical ingahlukaniswa ibe yimodi eminingi kanye nemodi eyodwa ngokusho kokudluliselwa kokukhanya kuyo.Imodi eyodwa ingakugwema ngokuphelele ukuhlakazeka kwe-modal, futhi inomphumela omuhle wokudlulisela, ayiphazamiseki kalula, futhi inomkhawulokudonsa omkhulu wokudluliswa kwemvamisa namandla amakhulu okudlulisela.Ijwayelana nomthamo omkhulu, ukuhanjiswa kwebanga elide.

Eyesibili i-modular ne-hybrid access design.Idizayini ye-modular iyavumelana nezimo futhi iyaguquguquka, enganikeza imisebenzi enwebekayo yokuthuthukiswa kwesistimu;ngenkambiso yokwenza idijithali, ukuhlanganiswa kobuchwepheshe be-SDI, kanye nokuhlalisana kwemikhiqizo ejwayelekile eyahlukene kuletha ukuphazamiseka kubakhiqizi.Ngakho-ke, .Ngokungeziwe ekwakhiweni kwe-modular, umklamo wokufinyelela we-hybrid nawo uyadingeka, uhlinzeka nge-interface yenethiwekhi ye-RJ-45, isixhumi esibonakalayo se-BNC, njll. kudivayisi, ukuze kokubili amasignali e-analog namasignali enethiwekhi kungadluliselwa ku-transceiver efanayo yokubona.

Okwesithathu ukucebisa amafomu okufaka isicelo ama-transceiver optical ocingo.Lobu buchwepheshe buzonciphisa kakhulu inani lemikhiqizo ekucacisweni okukodwa noma okubili, futhi amakhasimende angafinyelela kuyo ngokuthanda kwakhe.Ngokwesimo sephoyinti lokufinyelela i-fiber optical, kulula ukuhlela, futhi i-transceiver optical yocingo ngeke isanqunyelwa iphuzu-kuya-iphuzu, i-node, indandatho, ukuhlanganisa, njll. Umkhiqizo owodwa uhambisana nazo zonke izindlela zokufinyelela. , kunciphisa kakhulu inani lemicu optical esetshenziswayo.

Okwesine ukusetshenziswa kobuchwepheshe be-multiplexing (igama elijwayelekile le-EDM, TDM, ne-WDM), elixazulula ngokuyinhloko inkinga yomthamo omncane wokudlulisa we-fiber eyodwa, ikakhulukazi ukusetshenziswa kwe-HD-SDI, ethatha umkhawulokudonsa omkhulu futhi umthamo omkhulu webhizinisi.Uma ubuchwepheshe be-multiplexing kanye nobuchwepheshe bokuphindaphinda kwe-wavelength division bungahlanganiswa, umthamo ungathuthukiswa izikhathi ezimbalwa.Ngakho-ke, ucwaningo nokuthuthukiswa kobuchwepheshe be-multiplexing kubaluleke kakhulu.
