Chat optik (ke yo rele tou aparèy ONU) operatè lakay enstale nou an bay aksè nan rezo operatè a atravè PON (rezo optik pasif), konekte splitter optik la, epi konekte pò PON aparèy OLT operatè a.Done pwotokòl la konplètman diferan de LAN tradisyonèl la.Optical Cat konvèti done PON nan done Ethernet, ki jwe wòl konvèsyon pwotokòl, sètadi pòtay.
Limyè kalite chat: ka divize an EPON ONU, GPON ONU, XPON ONU selon estanda a
1. EPON ONU: EPON (Ethernet Passive Optical Network), ki baze sou estanda pwotokòl IEEE 802.3ah, bay uplink ak downlink to simetrik 1.25Gbps.
2. GPON ONU: GPON (Gigabit-Capable PON), ki baze sou ITU-T G.984.x pwotokòl estanda, bay uplink ak downlink pousantaj asimetri nan 1.244Gbps pou uplink ak 2.488Gbps pou downlink.
3. XPON ONU: double-mòd ONU, sipòte IEEE 802.3ah/ITU-T G.984.x pwotokòl estanda.
HDV OEM optik chat kalite: done kalite ONU, vwa kalite ONU, CATV kalite ONU, twa-rezo entegrasyon kalite ONU
1. Kalite done ONU: 1GE, 1GE + 1FE + WIFI, 1GE + 3FE + WIFI, 2GE + AC-WFI, 4GE + AC-WFI
2. Fonetik kalite ONU: 1GE+1FE+WIFI+1POTS、1GE+3FE+WIFI+1POTS、4GE+AC-WIFI +1POTS
