The wireless network may be a self-organizing wireless mesh network, and may generally operate as a logical signaling pathway via which information regarding optical states/statuses of PON components and/or related information is delivered from the field to back-end servers of the PON system. Accordingly, the system may include multiple in-common nodes (e.g., OLTs, LMTUs, etc.) which are included in both the PON and the wireless network.
