Ikati elibonayo (elaziwa nangokuthiI-ONUidivayisi) esihlinzekwe u-opharetha wethu ofakwe ekhaya ifinyelela inethiwekhi yomsebenzisi nge-PON (inethiwekhi ye-passive optical), ixhuma isihlukanisi esibonakalayo, bese ixhuma embobeni ye-PON ye-opharethaOLTidivayisi. 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-EPONI-ONU, GPONI-ONU, XPONI-ONUngokwendinganiso
1. EPONI-ONU: I-EPON (inethiwekhi ye-Ethernet Passive Optical Network), esekelwe kumthethonqubo we-IEEE 802.3ah, inikeza izinga lokulinganisa elikhuphukayo neliphansi le-1.25Gbps.
2. I-GPONI-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. XPONI-ONU: imodi ekabiliI-ONU, isekela i-IEEE 802.3ah/ITU-T G.984. x izinga lephrothokholi.
Uhlobo lwekati le-HDV OEM: uhlobo lwedathaI-ONU, uhlobo lwezwiI-ONU, uhlobo lwe-CATVI-ONU, uhlobo lokuhlanganisa lwenethiwekhi emithathuI-ONU
1. Uhlobo lwedathaI-ONU: 1GE, 1GE+1FE+WIFI, 1GE+3FE+WIFI, 2GE+AC-WFI, 4GE+AC-WFI
2. Uhlobo lwefonethikiI-ONU:1GE+1FE+WIFI+1POTS,1GE+3FE+WIFI+1POTS,4GE+AC-WIFI+1POTS
3. Uhlobo lwe-CATVI-ONU:1GE+1FE+WIFI+CATV,1GE+3FE+WIFI+CATV,1GE+1FE+CATV,2GE+AC-WIFI+CATV,4GE+AC-WIFI+CATV
4. Uhlobo lokuhlanganisa lwenethiwekhi emithathuI-ONU:1GE+1FE+WIFI+1POTS+CATV,1GE+3FE+WIFI+1POTS+CATV,4GE+AC-WIFI +1POTS+CATV
