Abstract
Techniques for predicting times-to-failure of components of a PON include generating an optical profile of a PON segment that has components including a last mile termination unit and an optical fiber received by the last mile termination unit, determining a drift over time of the segment's optical profile, and predicting the time-to-failure of a component of the segment based on the drift over time. The segment's optical profile corresponds to one or more characteristics of optical signals delivered over the segment (e.g., attenuation, changes in frequencies, changes in power outputs, etc.). Predicting the time-to-failure of the component may be based on, for example, a comparison of the drift over time of the segment's optical profile with drifts over time of other segments' optical profiles, a distance between the segment's optical profile and a boundary of a designated operating range of the PON, characteristics of the segment, etc.
