I-PON (i-Passive Optical Network) ithetha ukuba akukho nasiphi na isixhobo esisebenzayo kwaye sebenzisa kuphela i-Optical Fiber kunye ne-Passive Components phakathi kwe-OLT (i-Optical Line Terminal) kunye ne-ONU (iYunithi ye-Optical Network). Kwaye i-PON kubuchwephesha obuphambili bokuphumeza i-FTTB / FTTH, eyamkela ngokuyintloko inqaku kwinethiwekhi yamanqaku amaninzi ...

Ngophuhliso lothungelwano lonxibelelwano olusingise kwibroadband kunye nokuhamba, inkqubo yonxibelelwano engenazingcingo yefiber optical (ROF) idibanisa unxibelelwano lwefiber optical kunye nonxibelelwano olungenazingcingo, inika umdlalo opheleleyo kwiingenelo zebroadband kunye nokuchasana nokuphazamiseka kwemigca yefiber optical, njengoko ...

Ukutshintsha kwePoE sisitshixo esixhasa unikezelo lwamandla kwintambo yenethiwekhi. Xa kuthelekiswa nokutshintsha okuqhelekileyo, i-terminal yokufumana amandla (efana ne-AP, ikhamera yedijithali, njl.) Akufuneki ukuba ifakwe kwintambo yombane, kwaye ukuthembeka kwenethiwekhi yonke kuphezulu. Isishwankathelo saMandla phezu kwe-Et...

1. Isishwankathelo I-Intanethi yeZinto ixhobisa abenzi boluvo kwizinto ezahlukeneyo zokwenyani ezifana neegridi zamandla, oololiwe, iibhulorho, iitonela, iindlela ezinkulu, izakhiwo, iinkqubo zokubonelela ngamanzi, amadama, imibhobho ye-oyile kunye negesi, kunye nezixhobo zasekhaya, kwaye ziqhagamshele kwi-Intanethi, kwaye emva koko uqhube iinkqubo ezithile ukufikelela...

1. I-EPON network introduction EPON (i-Ethernet Passive Optical Network) iteknoloji ye-fiber optical access network ephumayo, eyamkela i-point-to-multipoint structure, i-passive optical fiber transmission mode, ngokusekelwe kwi-platform ye-Ethernet ye-high-speed kunye ne-TDM ye-division ye-MAC (MediaAccessControl). ) mna...

I-1.indlela yokufakela Ingaba ingaphakathi okanye ngaphandle, kufuneka uthathe amanyathelo achasene ne-static xa usebenzisa imodyuli ye-optical, kwaye uqinisekise ukuba uthinte imodyuli ye-optical ngezandla zakho ngelixa ugqoke iiglavu ezichasene ne-static okanye i-anti-static wrist strap. Akuvumelekanga ngokungqongqo ukubamba umnwe wegolide...
