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.

Fiber OTDRs are used in the US, Canada, and globally, and are considered the most effective way to test long fiber optic cables – that is, cables exceeding 800 feet or approximately 250 meters. OTDRs cultivate a collection of highly valuable information for the user, which can be stored to check later or to check against a blueprint. For when you need to confirm the quality of the fibers, connections, and splices, a GAOTek OTDR is the right product for the job and can also be applied in troubleshooting.

Different from sources and power meters which act as a direct method of measuring loss in a fiber optic cable, a fiber OTDR works indirectly. The product uses the light scattering in an optical fiber loss to make measurements. A fiber OTDR uses a high power laser transmitter to send a pulse of light down the fiber. The backscattered light and reflected light is what returns to the OTDR. This creates measurements and location data which can help to determine when something has gone awry.

Choose from GAOTek’s amazing selection of fiber OTDR testers, browsing basic and more affordable models to the more advanced. Some of our fiber OTDR testers include additional built-in fiber testers, including visual fault locators and optical power meters. All OTDRs are manufactured using cutting-edge technology prioritizing performance, productivity, and reliability regardless of where it’s been used.
