Olt Functional BlocksONU/OLT Functional BlocksTraffic Mapping - EthernetOMCIType AType BType CFunctional blocks are similar to the OLT. In the scenario that the ONU/OLT operates with a single PON interface (max 2 for protection purposes), the cross-connect function is omitted. Instead of this function, the service MUX and DEMUX are now responsible for traffic.See more on cisco Published: Dec 6, 2023ResearchGate
