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...

Kwixesha lanamhlanje le-Intanethi, zombini ukuhanjiswa kwenethiwekhi yeshishini kunye nokwakhiwa kweziko ledatha ayinakwenza ngaphandle kweemodyuli ze-optical kunye nokutshintsha. Iimodyuli ze-Optical zisetyenziselwa ukuguqula iimpawu zombane kunye ne-optical, ngelixa izitshintshi zisetyenziselwa ukuhambisa iimpawu ze-photoelectric. Phakathi kwee-optics ezininzi ...

Ii-transceivers ze-fiber optical zisetyenziswa ngokubanzi kwiindawo zenethiwekhi zangempela apho iintambo ze-Ethernet azikwazi ukugqunywa kwaye iifayili ze-optical kufuneka zisetyenziswe ukwandisa umgama wokuhambisa. Kwangaxeshanye, baye badlala indima enkulu ekuncedeni ukudibanisa imayile yokugqibela yemigca yefiber optical ...

Sisoloko sisiva ngokutshintsha kwefiber optic kunye neetransceivers zefiber optic. Phakathi kwazo, iiswitshi zefiber optic zizixhobo zokuhanjiswa kwenethiwekhi ezinesantya esiphezulu, ezikwabizwa ngokuba zizitshixo zefayibha kunye nokutshintsha kweSAN. Xa kuthelekiswa nokutshintsha okuqhelekileyo, basebenzisa iintambo zefiber optic njengesixhobo sokuhambisa...

Ngaphambi kokuba siqonde utshintsho lwe-PoE, kufuneka siqale siqonde ukuba yintoni i-PoE. I-PoE lubonelelo lwamandla ngaphezulu kwetekhnoloji ye-Ethernet. Yindlela yokubonelela ngokude amandla kwizixhobo zenethiwekhi ezixhunyiwe (ezifana ne-Wireless LAN AP, i-IP Phone, iBluetooth AP, ikhamera ye-IP, njl.) kwintambo yedatha ye-Ethernet esemgangathweni, el...
