I-Multiprotocol Label Switching (MPLS) yiteknoloji entsha ye-IP ye-backbone network. I-MPLS yazisa ingqikelelo yokutshintsha ileyibhile ejolise kunxibelelwano kwiinethiwekhi ze-IP ezingaxhunywanga, kwaye idibanisa itekhnoloji ye-Layer-3 yomzila kunye ne-Layer-2 yokutshintsha itekhnoloji, inika umdlalo opheleleyo wokuguquguquka kwendlela ye-IP...

I-Antenna sisixhobo esisebenzayo, esichaphazela kakhulu amandla e-OTA, uvakalelo, uluhlu lokugubungela kunye nomgama, ngelixa i-OTA yindlela ebalulekileyo yokuhlalutya kunye nokusombulula ingxaki yokuphuma. Ngesiqhelo, sithatha umlinganiselo we-eriyali ngokwezi parameters zilandelayo (ukusebenza kuya kuchaphazela ...

Inethiwekhi yokufikelela kwi-Optical (oko kukuthi, uthungelwano lofikelelo olunokukhanya njengendlela yothumelo, endaweni yocingo lobhedu, lusetyenziselwa ukufikelela kusapho ngalunye. Inethiwekhi yokufikelela kwi-Optical) .Uthungelwano lokufikelela kwi-Optical ngokubanzi lunamacandelo amathathu: i-terminal optical line OLT, inethiwekhi yokukhanya. iyunithi ONU, ukuhanjiswa kwamehlo...

Yintoni i-ONU? Namhlanje, i-ONU eneneni ixhaphake kakhulu kubomi bethu. Uqhagamshelo lwenethiwekhi olunikezelwa ngumsebenzisi olufakwe kwikhaya lomntu wonke lubizwa ngokuba yi-Optical Modem, ekwaziwa njengesixhobo se-ONU. Inethiwekhi yomsebenzisi iqhagamshelwe kwisixhobo sokukhanya, kwaye emva koko iqhagamshelwe kwizibuko le-PON le...

Xa sikhetha imodyuli ye-optical, ngaphezu kokupakishwa okusisiseko, umgama wokudlulisa, kunye nesantya sokudluliselwa, kufuneka sinikele ingqalelo kule miba ilandelayo: 1. Iintlobo zeFiber zohlobo lweFiber zingahlulwa zibe yimodi enye kunye ne-multi-mode. Umbindi wamaza wemowudi yendlela enye...

Igama elipheleleyo lemodyuli ye-optical i-transceiver optical, eyona sixhobo esibalulekileyo kwinkqubo yonxibelelwano ye-fiber optical. Inoxanduva lokuguqula isignali ye-optical efunyenweyo ibe ngumqondiso wombane, okanye ukuguqula igalelo lombane lombane ...
