Thaum peb kis tau mus ntev, peb feem ntau siv cov fibers optical xa mus.Vim hais tias qhov kev ncua deb ntawm fiber ntau optical fiber ntau ntev, feem ntau, qhov kev ncua deb ntawm ib hom fiber ntau yog ntau tshaj 20 kilometers, thiab kev sib kis ntawm ntau hom fiber ntau tuaj yeem ncav cuag li 2 km.Hauv fiber ntau optic tes hauj lwm, peb feem ntau siv fiber ntau media converter.Tom qab ntawd, thaum siv fiber ntau media converter, ntau tus phooj ywg yuav ntsib cov lus nug no:

Nqe Lus Nug 1: Puas yog fiber ntau media converter yuav tsum tau siv ua khub?

Nqe Lus Nug 2: Puas yog fiber ntau media converter ib qho rau kev txais thiab lwm qhov xa tuaj?Los yog ntev npaum li ob lub tshuab hloov pauv fiber ntau tuaj yeem siv ua khub?

Nqe Lus Nug 3: Yog tias lub tshuab hloov pauv fiber ntau yuav tsum tau siv ua khub, lawv puas yuav tsum yog tib hom thiab qauv?Los yog ib hom tshuaj twg tuaj yeem siv ua ke?

Teb: Optical fiber ntau transceivers feem ntau yog siv nyob rau hauv khub li photoelectric hloov dua siab tshiab khoom, tab sis nws kuj yog ib txwm siv optical fiber transceivers nrog fiber optic keyboards, thiab fiber ntau transceivers nrog SFP transceivers.Nyob rau hauv txoj cai, ntev li ntev raws li qhov optical transmission wavelength yog tib yam, Lub teeb liab encapsulation hom ntawv yog tib yam thiab txhua tus txhawb nqa ib qho kev cai kom paub txog kev sib txuas lus fiber ntau.

Feem ntau, ib hom dual-fiber (ob fibers yuav tsum tau rau kev sib txuas lus ib txwm) transceivers tsis muab faib ua transmitter thiab receiver, tsuav yog lawv tshwm nyob rau hauv khub, lawv yuav siv tau.

Tsuas yog ib leeg-fiber transceiver (ib fiber ntau yuav tsum muaj rau kev sib txuas lus ib txwm) yuav muaj lub transmitter thiab receiver.

Txawm hais tias nws yog dual-fiber transceiver lossis ib leeg-fiber transceiver los siv ua khub, ntau hom sib txawv tau sib xws.Tab sis qhov ceev, wavelength, thiab hom yuav tsum yog tib yam.

Qhov ntawd yog hais tias, tus nqi sib txawv (100M thiab 1000M) thiab qhov sib txawv wavelengths (1310nm thiab 1300nm) tsis tuaj yeem sib txuas lus.Tsis tas li ntawd, txawm tias ib leeg-fiber transceiver thiab dual-fiber transceiver ntawm tib hom tsim ib khub.sib txuas lus tsis tau.
