Abstract

A PON system includes both a PON via which optical services are delivered and a wireless network overlaying the PON. 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. Based on optical information received via the wireless network, the servers can localize the physical location of a PON fault to a particular geographical region of multiple regions serviced by the PON (in some cases narrowing the fault's physical location to a particular span, FDH, or optical terminal), and may dispatch a technician directly to the localized physical location to address the fault.
