Tikamatumiza maulendo ataliatali, nthawi zambiri timagwiritsa ntchito ma optical fibers kufalitsa.Chifukwa mtunda wotumizira wa fiber fiber ndi wautali kwambiri, nthawi zambiri, mtunda wotumizira wa fiber single-mode ndi wopitilira makilomita 20, ndipo mtunda wotumizira wamitundu yambiri umatha kufikira makilomita awiri.Mu fiber optic network, nthawi zambiri timagwiritsa ntchito fiber media converter.Kenako, mukamagwiritsa ntchito fiber media converter, anzanu ambiri amakumana ndi mafunso awa:

Funso 1: Kodi fiber media converter iyenera kugwiritsidwa ntchito pawiri?

Funso 2: Kodi fiber media converter imodzi yolandila ndi ina yotumiza?Kapena bola ngati ma fiber media converter awiri atha kugwiritsidwa ntchito ngati awiri?

Funso 3: Ngati fiber media converter iyenera kugwiritsidwa ntchito pawiri, kodi ziyenera kukhala zamtundu womwewo?Kapena kodi mtundu uliwonse ungagwiritsidwe ntchito kuphatikiza?

Yankho: Ma transceivers opangira ma fiber nthawi zambiri amagwiritsidwa ntchito pawiri ngati zida zosinthira zithunzi, komanso ndizabwino kugwiritsa ntchito ma transceivers opangira ma fiber optic, ndi ma transceivers a fiber okhala ndi ma transceivers a SFP.M'malo mwake, malinga ngati kuwala kwa kuwala kwa kuwala kuli kofanana, mtundu wa encapsulation wa chizindikiro ndi wofanana ndipo zonse zimathandizira ndondomeko inayake kuti izindikire kuyankhulana kwa fiber.

Nthawi zambiri, single-mode dual-fiber (ziwiri zimayenera kulumikizana bwino) ma transceivers samagawidwa kukhala ma transmitter ndi olandila, bola akuwoneka awiriawiri, amatha kugwiritsidwa ntchito.

Ndi transceiver ya fiber imodzi yokha (chingwe chimodzi chimafunika kuti tizilankhulana bwino) chizikhala ndi chotumizira ndi cholandila.

Kaya ndi transceiver yawiri-fiber kapena transceiver ya fiber imodzi kuti igwiritsidwe ntchito pawiri, mitundu yosiyanasiyana imagwirizana.Koma liwiro, kutalika kwa mafunde, ndi mawonekedwe ayenera kukhala ofanana.

Izi zikutanthauza kuti, mitengo yosiyana (100M ndi 1000M) ndi mafunde osiyanasiyana (1310nm ndi 1300nm) sangathe kulankhulana.Kuphatikiza apo, ngakhale transceiver ya fiber imodzi ndi transceiver yamitundu iwiri yamtundu womwewo imapanga awiri.sangathe kulankhulana wina ndi mzake.
