Frontier Communications Parent has been granted a patent for techniques to maintain equipment in a passive optical network (PON). The system uses current optical profiles to monitor segments of the PON and detects if a segment’s profile is outside the designated operating range. By comparing the drifts over time of the segment’s profile with other segments that share common endpoints, the system identifies the component of the PON that requires maintenance.

Maintenance system for a passive optical network (pon)
A recently granted patent (Publication Number: US11742944B1) describes a system and method for maintaining equipment in a passive optical network (PON). The system includes one or more processors and memories storing computer-executable instructions. When executed, these instructions allow the system to detect the need for maintenance based on differences in the drift over time of the optical profile of a segment of the PON compared to other segments. The segments share a common endpoint.
The optical profile of the segment can be based on various factors, such as the attenuation of optical signals, changes in frequencies or power outputs of the signals, or the density of last mile termination units serviced by the segment. The system can also determine the optical profile based on measurements obtained at upstream or downstream endpoints of the segment.
The system can detect the need for maintenance when the magnitude of the differences exceeds a predefined tolerance level or range. It can also predict the time-to-failure of the specific segment endpoint or optical fiber. This prediction includes estimating when the optical profile of a segment will exceed an upper failure threshold or fall below a lower failure threshold.
The system can transmit an indication of the specific segment endpoint or optical fiber in need of maintenance to a user interface or another computing device. It can also be implemented in one or more servers of the PON or a portable computing device associated with the network.
The method of maintaining equipment in the PON involves detecting the need for maintenance based on differences in the drift over time of the optical profile of a segment compared to other segments. It also includes transmitting an indication of the specific segment endpoint or optical fiber in need of maintenance to a user interface or computing device. The optical profile can be determined based on factors such as attenuation, frequency changes, power outputs, density of last mile termination units, or measurements obtained at endpoints. The method can also involve predicting the time-to-failure of the specific segment endpoint or optical fiber and comparing the drift over time of the segment with historical profiles.
Overall, this patent describes a system and method that can effectively detect and predict maintenance needs in a passive optical network, allowing for proactive maintenance and improved network performance.
