Using 3-GIS | Web and Mobile to find a fault location

Written by Brad Greene | Mar 4, 2024 2:00:00 PM

We all know it’s going to happen eventually. It does not matter who are you or how prepared you think are; your fiber is going to break. There are an unfathomable number of miles of extremely thin glass hanging in the air, buried underground, or just looped over and over.  

When a fault occurs, it can be a daunting task to test and locate exactly where that may be. Fortunately, there are tools and technology available at our fingertips to locate these faults quickly and accurately, so we can get the network back up and running as quickly as possible. Let’s look at a few of the tools 3-GIS users have at their disposal that can help during an outage scenario.

 

Single Point of Failure

When you start receiving calls from customers reporting an outage or notifications from monitoring equipment of significant signal loss; the Single Point of Failure tool allows you to determine where the shared assets in the network are located. Once you have identified where the potential problem may be occurring, you can dispatch a technician to the right location in the field to investigate and resolve the problem.

 OTDR Trace

With 3-GIS | Mobile in hand, a field technician can get driving directions to the asset located through Single Point of Failure and, once there, can use an OTDR testing device to get a reading of the signal loss and distance. Entering the resulting distance from the OTDR test into 3-GIS | Mobile provides the location of that fault on the map, taking into consideration all slack and any sag. This eliminates the time-consuming task of calling back to the office and having someone look up where that distance might be. Instead, the technician in the field can immediately identify the location of the fault and instantly navigate to that location using GPS-provided directions.

Signal Trace

Once the technician arrives at the fault, they will need to identify the customers affected by the cut. Using Signal Trace in 3-GIS | Mobile, the technician can see all the circuits and signals on a cable, understand what customer is on each strand in the affected cable, and even generate a splice report if desired.

3-GIS | Web and 3-GIS | Mobile work together to seamlessly provide field crews with the tools and the insight needed to detect and respond to issues faster. By embracing these technologies, we not only streamline fault detection and resolution processes, but also minimize disruptions for customers. In a world where the unexpected is inevitable, these tools make all the difference in maintaining a robust and resilient fiber optic network.
