OTDRs
An Optical Time Domain Reflectometer (OTDR) tests the integrity of a fiber optic cable. Using a fiber OTDR, a technician can verify splice loss, identify length, and very easily locate faults in the cable. Another use is to verify the accurate installation of a fiber optic cable when it’s newly installed. If/when problems arise or if an issue is suspected in the future, a fiber OTDR can then compare the images from the original trace to the present state of the cable.
