Kucing optik (uga dikenal minangka piranti ONU) sing diwenehake dening operator sing diinstal ing omah kita ngakses jaringan operator liwat PON (jaringan optik pasif), nyambungake splitter optik, lan banjur nyambung menyang port PON piranti OLT operator.Data protokol temen beda saka LAN tradisional.Optical Cat ngowahi data PON menyang data Ethernet, sing nduweni peran konversi protokol, yaiku gateway.
Tipe kucing cahya: bisa dipérang dadi EPON ONU, GPON ONU, XPON ONU miturut standar
1. EPON ONU: EPON (Ethernet Passive Optical Network), adhedhasar standar protokol IEEE 802.3ah, nyedhiyakake uplink lan downlink tingkat simetris 1.25Gbps.
2. GPON ONU: GPON (Gigabit-Capable PON), adhedhasar ITU-T G.984.x standar protokol, nyedhiyakake uplink lan downlink tarif asimetris 1.244Gbps kanggo uplink lan 2.488Gbps kanggo downlink.
3. XPON ONU: dual-mode ONU, ndhukung IEEE 802.3ah/ITU-T G.984.x standar protokol.
Tipe kucing optik OEM HDV: tipe data ONU, tipe suara ONU, tipe CATV ONU, tipe integrasi tiga jaringan ONU
1. Tipe data ONU: 1GE, 1GE+1FE+WIFI, 1GE+3FE+WIFI, 2GE+AC-WFI, 4GE+AC-WFI
2. Tipe fonetik ONU:1GE+1FE+WIFI+1POTS,1GE+3FE+WIFI+1POTS,4GE+AC-WIFI +1POTS
3. Tipe CATV ONU:1GE+1FE+WIFI+CATV,1GE+3FE+WIFI+CATV,1GE+1FE+CATV,2GE+AC-WIFI+CATV,4GE+AC-WIFI+CATV
4. Tipe integrasi telung jaringan ONU: 1GE+1FE+WIFI+1POTS+CATV,1GE+3FE+WIFI+1POTS+CATV,4GE+AC-WIFI +1POTS+CATV
