1. Nguwuphi umahluko phakathi kweeModyuli zeSFP kunye neMedia Converter? Iimodyuli ze-SFP zisetyenziswa kakhulu kumqolo wenethiwekhi yefiber optical, ngelixa i-transceivers optical zizixhobo nje ezandisa iintambo zenethiwekhi.

1. Ibonelela ngogqithiso lwedatha yokulibaziseka okuphantsi kakhulu. 2. Yiba elubala ngokupheleleyo malunga neeprothokholi zenethiwekhi. 3. I-Chipset ekhethekileyo ye-ASIC isetyenziselwa ukuqonda ukuhanjiswa kwesantya somgca wedatha. I-ASICS eCwangcisiweyo igxininisa inani lemisebenzi kwitshiphu, ngoyilo olulula, ukuthembeka okuphezulu, ukusetyenziswa kwamandla okuncinci kunye ...

I-Module ye-SFP iqukethe i-optical device, isiphaluka esisebenzayo kunye ne-interface ebonakalayo. Isixhobo sokubona siquka iinxalenye ezithumelayo kunye nokwamkela. Inxalenye yokuhambisa yile: igalelo lekhowudi ethile yeempawu zombane, ngokusebenzisa inkqubo yangaphakathi yomqhubi we-chip, ukuqhuba i-semiconducto ...

Imodyuli ye-optical iqukethe icandelo le-photoelectronic, isiphaluka esisebenzayo, kunye ne-interface ebonakalayo. Icandelo le-photoelectronic libandakanya ukuhambisa kunye nokwamkela iinxalenye. Ukuyibeka ngokulula, umsebenzi wemodyuli ye-optical kukuguqulwa kwe-photoelectric. Isiphelo sokuthumela siguqula i-si yombane...

I-WDM PON yi-point-to-point passive optical network isebenzisa i-wavelength division multiplexing technology. Okokuthi, kwifiber efanayo, inani leemitha ezisetyenziswa kumacala omabini lingaphezulu kwe-3, kwaye ukusetyenziswa kwe-wavelength division multiplexing iteknoloji ukufezekisa ukufikelela kwe-uplink kunokubonelela ngegrea ...

Inkqubo ye-EPON iqulethe iiyunithi ezininzi zenethiwekhi ye-optical (ONU), i-terminal ye-optical line (OLT), kunye nenethiwekhi enye okanye ngaphezulu (jonga i-Figure 1). Kwisalathiso sokwandisa, isignali ethunyelwe yiOLT isasazwa kuzo zonke ii-ONU. 8h Guqula ifomathi yesakhelo, chaza kwakhona indawo engaphambili, kwaye wongeze ixesha...
