Ucing optik (ogé katelah alat ONU) disadiakeun ku operator dipasang imah urang ngakses jaringan operator urang ngaliwatan PON (jaringan optik pasif), nyambungkeun splitter optik, lajeng nyambung ka port PON alat OLT operator urang.Data protokol sagemblengna béda ti LAN tradisional.Optical Cat ngarobah data PON kana data Ethernet, anu maénkeun peran konversi protokol, nyaéta gateway.
Jenis ucing lampu: bisa dibagi kana EPON ONU, GPON ONU, XPON ONU nurutkeun standar
1. EPON ONU: EPON (Ethernet Passive Optical Network), dumasar kana standar protokol IEEE 802.3ah, nyayogikeun uplink sareng downlink laju simetris 1.25Gbps.
2. GPON ONU: GPON (Gigabit-Capable PON), dumasar kana ITU-T G.984.x standar protokol, nyadiakeun uplink na downlink ongkos asimétri tina 1.244Gbps pikeun uplink jeung 2.488Gbps pikeun downlink.
3. XPON ONU: dual-mode ONU, ngarojong IEEE 802.3ah / ITU-T G.984.x standar protokol.
Tipe ucing optik HDV OEM: tipe data ONU, tipe sora ONU, tipe CATV ONU, tipe integrasi tilu jaringan ONU
1. Tipe data ONU: 1GE, 1GE+1FE+WIFI, 1GE+3FE+WIFI, 2GE+AC-WFI, 4GE+AC-WFI
2. Jenis fonétik ONU: 1GE+1FE+WIFI+1POTS,1GE+3FE+WIFI+1POTS,4GE+AC-WIFI +1POTS
3. Jenis CATV ONU: 1GE+1FE+WIFI+CATV,1GE+3FE+WIFI+CATV,1GE+1FE+CATV,2GE+AC-WIFI+CATV,4GE+AC-WIFI+CATV
4. Tipe integrasi tilu jaringan ONU: 1GE+1FE+WIFI+1POTS+CATV,1GE+3FE+WIFI+1POTS+CATV,4GE+AC-WIFI +1POTS+CATV
