An optical line terminal (OLT) system for a passive optical network (PON) may include a processor, an OLT Medium Access Control (MAC) device communicatively coupled to PON ports, and a switch device communicatively coupled to the OLT MAC device via an Ethernet interface. The processor may map logical identifiers of each PON port to tunnel identifiers, where each tunnel identifier is indicative of a logical identifier and its corresponding PON port. The OLT MAC device may receive upstream data items that include logical identifiers over the PON ports. The OLT MAC device may replace the logical identifier of each upstream data item with the tunnel identifier that is mapped to the logical identifier and the PON port over which the upstream data item was received. The OLT MAC device may transmit, over the Ethernet interface to the switch device, the upstream data items including the tunnel identifiers. |
