Kucing optik (uga dikenal minangkaONUpiranti) 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 operator.OLTpiranti. 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 EPONONU, GPONONU, XPONONUmiturut standar
1. EPONONU: EPON (Ethernet Passive Optical Network), adhedhasar standar protokol IEEE 802.3ah, nyedhiyakake uplink lan downlink tingkat simetris 1.25Gbps.
2. GPONONU: 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. XPONONU: dual-modeONU, ndhukung IEEE 802.3ah/ITU-T G.984. x standar protokol.
