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...

I-Fiber Optic Sensor I-fiber optic sensor yenziwe ngumthombo wokukhanya, i-fiber yesiganeko, i-fiber ephumayo, i-modulator yokukhanya, i-detector yokukhanya, kunye ne-demodulator. Umgaqo osisiseko kukuthumela ukukhanya komthombo wokukhanya kwindawo yokumodareyitha ngefiber yesiganeko, kunye nokukhanya kusebenzisana ...

Ulawulo lwenethiwekhi sisiqinisekiso sokuthembeka kwenethiwekhi kunye nendlela yokuphucula ukusebenza kwenethiwekhi. Ukusebenza, ukulawula kunye nokugcinwa kwemisebenzi yolawulo lwenethiwekhi kunokunyusa kakhulu ixesha elikhoyo lenethiwekhi, kunye nokuphucula izinga lokusetyenziswa, ukusebenza kwenethiwekhi, inkonzo ...

1 Intshayelelo Ngophuhliso olukhawulezayo lwetekhnoloji yokufikelela kwibroadband, ubugcisa obahlukeneyo obuvelayo bokufikelela kwibroadband buvele emva kwemvula. Emva kokuba iteknoloji ye-PON iteknoloji ye-DSL kunye ne-cable technology, enye iqonga elifanelekileyo lokufikelela, i-PON inokubonelela ngokuthe ngqo ngeenkonzo ze-optical okanye i-FTTH s...
