1. Yimuphi umehluko phakathi kweSFP Modules & Media Converter? Amamojula e-SFP asetshenziswa kakhulu kumgogodla wenethiwekhi ye-fiber optical, kuyilapho ama-transceiver optical angamadivayisi anweba izintambo zenethiwekhi.

1. Ihlinzeka ngokudluliswa kwedatha yokubambezeleka okuphansi kakhulu. 2. Yiba obala ngokugcwele mayelana nezivumelwano zenethiwekhi. 3. I-chipset ye-ASIC ekhethekile isetshenziselwa ukubona ukudluliselwa kwesivinini somugqa wedatha. I-ASICS ehlelekayo igxilisa inani lemisebenzi ku-chip, enomklamo olula, ukwethembeka okuphezulu, ukusetshenziswa kwamandla okuncane kanye ...

I-SFP Module iqukethe idivayisi ye-optical, isekethe esebenzayo kanye ne-optical interface. Umshini obonayo uqukethe izingxenye ezidlulisayo nezokwamukela. Ingxenye yokudlulisela yilezi: okokufaka kwenani lekhodi elithile lamasignali kagesi, ngokucubungula i-chip yomshayeli wangaphakathi, ukushayela i-semiconducto...

Imojula yokubona iqukethe ingxenye ye-photoelectronic, isifunda esisebenzayo, nesixhumi esibonakalayo esibonakalayo. Ingxenye ye-photoelectronic iqukethe izingxenye ezidlulisayo nokwamukelayo. Ukukubeka kalula, umsebenzi we-optical module ukuguqulwa kwe-photoelectric. Isiphetho sokuthumela siguqula i-electric si...

I-WDM PON iyinethiwekhi ye-point-to-point passive passive esebenzisa ubuchwepheshe be-wavelength division multiplexing. Okusho ukuthi, ku-fiber efanayo, inani lamaza amaza asetshenziswa kuzo zombili izinkomba lingaphezu kuka-3, futhi ukusetshenziswa kobuchwepheshe be-wavelength division multiplexing ukuze kuzuzwe ukufinyelela kwe-uplink kunganikeza amafutha...

Uhlelo lwe-EPON luqukethe amayunithi enethiwekhi amaningi optical (ONU), itheminali yomugqa optical (OLT), kanye nenethiwekhi eyodwa noma ngaphezulu optical (bona Umfanekiso 1). Esiqondisweni sesandiso, isignali ethunyelwe i-OLT isakazwa kuwo wonke ama-ONU. 8h Lungisa ifomethi yozimele, chaza kabusha ingxenye engaphambili, bese wengeza isikhathi...
