Mesh-based fault detection in passive optical networks

A method for localizing faults within a Passive Optical Network (PON), the method comprising:

• receiving, at a fault localizer of the PON and via a wireless mesh network of the PON, one or more signals indicative of respective losses of optical connectivity, with the PON, of a multiplicity of last mile termination units of the PON,
• the wireless mesh network including a plurality of nodes, the plurality of nodes including a plurality of last mile termination units of the PON, the plurality of last mile termination units including the multiplicity of last mile termination units, each last mile termination unit configured to, upon a detection of a loss of optical connectivity of the each last mile termination unit with the PON, transmit, via the wireless mesh network, a signal indicative of the loss of optical connectivity of the each last mile termination unit with the PON, and
• the fault localizer comprising computer-executable instructions stored on one or more memories and executable by one or more processors associated with the PON;
• localizing, by the fault localizer, a physical location of a fault within the PON to a particular geographical region of a plurality of geographical regions among which an entirety of components of the PON are physically disposed, the localizing of the physical location of the fault based on the received one or more signals and a layout indicating interconnections between a multiplicity of PON components, the multiplicity of PON components included in the entirety of PON components;
• and
• causing, by the fault localizer, an indication of the particular geographical region to be provided to at least one of a user interface or another computing device.
