Ikati elikhanyayo (elibuye laziwe ngokuthi idivayisi ye-ONU) elihlinzekwe u-opharetha ofakwe ekhaya lifinyelela inethiwekhi yomsebenzisi nge-PON (inethiwekhi ye-passive optical), ixhuma isihlukanisi esibonakalayo, bese ixhuma embobeni ye-PON yedivayisi ye-OLT yesisebenzisi.Idatha yephrothokholi ihluke ngokuphelele ku-LAN yendabuko.I-Optical Cat iguqula idatha ye-PON ibe idatha ye-Ethernet, edlala indima yokuguqulwa kwephrothokholi, okungukuthi isango.
Uhlobo lwekati olukhanyayo: lungahlukaniswa lube yi-EPON ONU, GPON ONU, XPON ONU ngokwezinga
1. I-EPON ONU: I-EPON (i-Ethernet Passive Optical Network), esekelwe kuzinga lephrothokholi ye-IEEE 802.3ah, inikeza izinga lokulinganisa elikhuphukayo neliphansi le-1.25Gbps.
2. I-GPON ONU: I-GPON (i-Gigabit-Capable PON), esekelwe ku-ITU-T G.984.x izinga lephrothokholi, lihlinzeka ngezilinganiso ezilinganisa phezulu naphansi ze-asymmetric engu-1.244Gbps ye-uplink kanye ne-2.488Gbps ye-downlink.
3. XPON ONU: imodi ekabili ye-ONU, isekela i-IEEE 802.3ah/ITU-T G.984.x izinga lephrothokholi.
Uhlobo lwekati elibonakalayo le-HDV OEM: uhlobo lwedatha i-ONU, uhlobo lwezwi i-ONU, uhlobo lwe-CATV i-ONU, uhlobo lokuhlanganiswa kwamanethiwekhi amathathu i-ONU
1. Uhlobo lwedatha i-ONU: 1GE, 1GE+1FE+WIFI, 1GE+3FE+WIFI, 2GE+AC-WFI, 4GE+AC-WFI
2. Uhlobo lwefonetiki i-ONU:1GE+1FE+WIFI+1POTS,1GE+3FE+WIFI+1POTS,4GE+AC-WIFI +1POTS
3. Uhlobo lwe-CATV ONU:1GE+1FE+WIFI+CATV,1GE+3FE+WIFI+CATV,1GE+1FE+CATV,2GE+AC-WIFI+CATV,4GE+AC-WIFI+CATV
4. Uhlobo lokuhlanganisa lwamanethiwekhi amathathu i-ONU:1GE+1FE+WIFI+1POTS+CATV,1GE+3FE+WIFI+1POTS+CATV,4GE+AC-WIFI +1POTS+CATV
