Installing a point-to-point fiber optic cable with many fibers inside can be often a challenge, especially when trying to keep track in real time of where you are in the process. Which fibers have I already tested?

Which fibers passed and which ones failed? One approach is to manually track progress with traditional methods like an online spreadsheet, or even with pen and paper. This manual process is error prone. It may result in re-testing fibers you have already successfully tested, or

not being able to quickly identify those fibers that failed and need to be retested.
