Systems and methods of performing reflection and loss analysis of optical-time-domain-reflectometry (otdr) data acquired for monitoring the status of passive optical networks

A method of characterizing a passive optical network, comprising;

• obtaining optical-time-domain-reflectometry (OTDR) data from the passive optical network;
• creating a data array from the optical-time-domain-reflectometry (OTDR) data;
• conducting an event analysis to determine the existence of reflection events within the passive optical network, and to identify the reflection events;
• conducting a reflection event analysis to further validate and analyze each of the idetified reflection events based on a system impulse response template and an event probability calculation;
• determining a reflection type and a reflection status for each of the reflection events;
• and
• reporting the reflection type and reflection analysis for each of the plurality of identified reflection events.

A method for performing reflection and loss analysis of optical-time-domain-reflectometry (OTDR) data acquired for the purpose of characterizing the status of passive optical networks using a previously acquired reflectometry data file retrieved from a passive optical network, the method comprising:

• creating a data array from the previously acquired reflectometry data file;
• conducting reflection analysis of the data array to identify a plurality of reflection events, and summarize a plurality of parameters related to each of the plurality of reflection events;
• conducting an event analysis to further validate and analyze each of the reflection events based on a system impulse response template and an event probability calculation;
• determining a reflection type and a reflection status for each of the reflection events;
• conducting loss analysis of the data array to identify a plurality of loss events, and to summarize a plurality of parameters related to each of the plurality of loss events;
• conducting an event analysis to further validate and analyze each of the loss events based on standard loss measurements, probability calculations and a fiber-equivalent metric, resulting in a loss characterization for each of the loss events;
• determining a loss type and a loss status for each of the loss events;
• and
• generating a report characterizing the passive optical network.
