1. A method for localizing faults within a Passive Optical Network (PON), the method comprising:
receiving, by a fault localizer of the PON, one or more signals via an intermediate node of a wireless mesh network, the one or more signals indicative of respective losses of connectivity, with the PON, of two or more PON components included in an entirety of components of the PON, the intermediate node disposed in between the fault localizer and at least one of the two or more PON components;
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 (i) the one or more signals, and (ii) a layout indicating interconnections between a multiplicity of PON components of the PON,
the fault localizer comprising computer-executable instructions stored on one or more memories and executable by one or more processors associated with the PON, and
one or more last mile termination units of the PON are respective nodes of the wireless mesh network.
