Cattus opticus (etiam ONU fabrica) providetur a domo nostra operante inaugurata accessibus retis operantis per PON (retem opticam passivam) SCHISMATICUS optica coniungit et deinde ad PON portum artificii operantis OLT coniungit.Protocollum notitiarum a tradito LAN omnino differt.Optical Cattus PON notitias in Aernet notitias convertit, quae partes protocolli conversionis, id est portae, agit.
Genus feles levis: dividi potest in EPON ONU, GPON ONU, XPON ONU secundum mensuram
1. EPON ONU: EPON (Aethernet Passive Optical Network), in IEEE 802.3ah protocollo innixus, uplink et downlink ratem symmetricam praebet 1.25Gbps.
2. GPON ONU: GPON (Gigabit-Capable PON), ex ITU-T G. 984.vexillum protocollum x, uplink and downlink praebet rates asymmetricas of 1.244Gbps for uplink and 2.488Gbps for downlink.
3. XPON ONU: dual-modus ONU, favens IEEE 802.3ah/ITU-T G.984.vexillum protocollum x.
