Ulwazi

Namhlanje, kwiiprojekthi zonxibelelwano zenethiwekhi zangoku, i-transceivers optical, i-transceivers optical fiber, kunye neemodem ezibonakalayo zinokuthi zisetyenziswe ngokubanzi kwaye zihlonitshwe kakhulu ngabasebenzi bokhuseleko. Ke, ngaba uyawazi umahluko phakathi kwezi zintathu zicacileyo? Imodem yokubona luhlobo lwezixhobo...

I-Optical fiber transceiver yiyunithi yokuguqula imidiya ye-Ethernet etshintshisa umgama omfutshane ojijekileyo weempawu zombane kunye nemiqondiso yokubona ekude. Ngokweemfuno zayo, ihlulwe kakhulu ibe yi-fiber optical transceivers kunye ne-dual-fiber optical transceivers.Okulandelayo...

Isakhiwo esisisiseko se-fiber optical I-fiber engenanto ye-fiber optical idla ngokuhlukana ibe ngamacandelo amathathu: i-core, i-cladding kunye ne-coating. I-fiber core kunye ne-cladding yenziwe ngeglasi enezalathisi ezahlukeneyo ze-refractive, i-central is a high refractive index glass core (germanium-doped silica), a...

1.I-PON Intshayelelo (1) Yintoni i-PON PON (i-passive optical network) iteknoloji (kuquka i-EPON, i-GPON) iyona teknoloji yokuphunyezwa kwe-FTTx (i-fiber ukuya ekhaya). Inokugcina izibonelelo zefiber yomqolo kunye namanqanaba enethiwekhi, kwaye inokubonelela ngeendlela ezimbini eziphezulu ze-bandwidth ...

Ukusetyenziswa kwee-transceivers ze-fiber optical kwiiprojekthi zangoku ezibuthathaka zixhaphake kakhulu, ngoko sikhetha njani ii-transceivers zefiber optical kwiiprojekthi zobunjineli? Xa i-fiber optic transceiver isilela, ungayigcina njani? 1.Yintoni i-fiber optic transceiver? I-optical fiber transceiver ikwabizwa ngokuba yi-ph...

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...
