Optical transceivers zvakare optical chiratidzo chekufambisa michina. Vekunze optical transceivers vane tekinoroji yakakura asi inodhura. Kunyangwe epamba optical transceivers asina kukura muhunyanzvi tekinoroji, haadhure zvakakwana kubata neayo emukati. Zvino chii chinosarudzwa che optical transceivers?

Kuchengetedza kwekutenga optical transceivers: Kubva pachiratidzo chakatumirwa kune optical fiber, optical transceivers inogona kugoverwa kuva analog optical transceivers inobva paanalog teknolojia uye digital optical transceivers inobva pamagetsi emagetsi. Nheyo yekushanda yeanalog optical transceiver haisi chinhu kunze kwekugadzirisa uye demodulation, kusefa uye kusanganiswa kwechiratidzo, etc. Ingave iri LED kana LD, maitiro ayo ekugadzirisa photoelectric haasi mutsara. Muchirongwa chekutumira chiratidzo, kukanganisa, kupindira uye mamwe matambudziko asingadzivisiki mukugadziriswa kweanalogi hazvidzivisiki, uye kune hunyanzvi husingagoneki muhukuru hwekutapurirana uye kusanganiswa kwesevhisi yakawanda. kuoma.

Mamiriro ezvinhu e digital optical transceivers akasiyana. Kune matunhu maviri chete e "fiber uye "hapana faibha" mune optical fiber. Naizvozvo, mutsara weiyo sosi yemwenje hauna kukwirira kana kupotsa hapana chinodiwa, nekudaro kudzivirira kurasikirwa kwechiratidzo mukugadzirisa. Uye zvakare, madhijitari optical transceivers ari nyore kuwana akawanda-channel uye yakasanganiswa kutapurirana kweakawanda masaini. Sezvo ivo vachingoshandurwa kuva masaini edhijitari, kutapurirana kwematanho akawanda uye akawanda masaini anogona kuwanikwa nyore nerubatsiro rweTDM (Time Division Multiplexing) tekinoroji. Vagadziri varipo vanogadzira transceiver vanogona kutumira 10 isina kudzvanywa chaiyo-nguva yevhidhiyo mifananidzo pane imwe wavelength chiteshi panguva.

Optical fiber network topology, optical fiber network topology inosarudza rudzi rwevhidhiyo optical transceiver. Zvinoenderana neiyo topology ye optical fiber transmission network, kuwedzera kune yechinyakare point-to-point transceivers optical transceivers, kune zvakare node-mhando uye mhete network optical transceivers kusarudza kubva. Iyo node-mhando yevhidhiyo optical transceiver inosanganisa kumberi-kumagumo node muketani network kana muti network. Muchina wenodhi unotanga wagamuchira chiratidzo panzvimbo yega yega, woishandura kuita chiratidzo chemagetsi, wobva wachinjana uye wowedzera chiratidzo nenodhi yenzvimbo. Mushure mekushandurwa kwemafotoelectric, iyo WDM tekinoroji inoshandiswa pakuwanda. Shandisa optical fiber kutapurirana. Hapana analog-to-digital shanduko inoitwa pane imwe neimwe node, iyo inoderedza kuderedzwa kwechiratidzo.

Iyo yekumhanyisa yekufambisa kweiyo optical transceiver inokurumidza, iyo skrini yakajeka, uye inogona kushandiswa mune ese marudzi ekunze. Iine huwandu hwakawanda hwekuita uye inoshandiswa zvakanyanya muindasitiri.
