Ukubuka Kafushane Uchungechunge lwe-JHA700-E304 luyifayibha ekufinyeleleni kwezinsiza eziningi zasekhaya i-EPON ONU. Isekelwe kubuchwepheshe bokusebenza be-EPON obuvuthiwe, obuzinzile, obubiza kakhulu futhi inokushintsha kwe-gigabit Ethernet, i-WDM kanye nobuchwepheshe be-HFC. Uchungechunge lwe-JHA700-E304 lunomkhawulokudonsa ophezulu, ukuthembeka okuphezulu, ukuphathwa okulula kanye nesiqinisekiso sekhwalithi enhle yesevisi (QoS) esisebenza ngobuchwepheshe bemishini sihlangabezana nezidingo ze-IEEE802.3ah futhi sinokuhambisana okuhle nabakhiqizi bezinkampani zangaphandle i-OLT. Ubuchwepheshe be-EPON wuhlobo lobuchwepheshe obusafufusa obusebenzisa ubuchwepheshe be-PON kanye nobuchwepheshe be-Ethernet futhi buwuhlobo lwephoyinti lobuchwepheshe benethiwekhi enamaphuzu amaningi. I-OLT ngokusebenzisa inethiwekhi ye-passive optical ukuxhuma i-ONU eminingi nge-fiber eyodwa bidirectional technical ayivamisile ukusebenzisa izinsiza ze-fiber ukuhlangabezana nabaqhubi bezidingo zokufinyelela zabasebenzisi abaningi. Yamukela ubuchwepheshe be-fiber WDM eyodwa ene-downlink wavelength 1550nm kanye ne-1490nm, i-uplink wavelength 1310nm. Idinga kuphela i-fiber eyingqikithi eyodwa ukuze idlulise idatha nesevisi ye-CATV.
