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...

1 Intshayelelo ye-PoE ikwabizwa ngokuba yiPower over LAN (PoL) okanye i-Active Ethernet, ngamanye amaxesha ibizwa ngokuba yiPower over Ethernet ngokufutshane. Olu luphawu lwamva nje oluqhelekileyo olusebenzisa iintambo zothumelo lwe-Ethernet ezikhoyo zokuhambisa idatha kunye namandla ngaxeshanye, kwaye zigcina i-compatib...

Isishwankathelo saMandla phezu koMbane (POE) I-POE (Amandla phezu kwe-Ethernet) ibhekisela kwezinye ii-terminals ezisekelwe kwi-IP (ezifana neefowuni ze-IP, ii-wireless LAN access points AP, iikhamera zenethiwekhi, njl.) ngaphandle kokutshintsha i-Ethernet Cat.5 ekhoyo i-wiring infrastructure. Ngelixa uthumela imiqondiso yedatha, ibonelela ngamandla eDC ...
