The insertion loss is calculated from the proportional amplitude change of the backscattered light. The location of each event and the overall cable length are calculated based on the round-trip time of the light pulse traveling through the fiber core. A photodiode measures the returning light energy or optical power (reflected and scattered back) over time and converts it into an electrical value that is sampled, amplified, and graphically displayed on a screen. The OTDR sends a pulse of light energy (optical power), generated by a laser diode, into one end of an optical fiber. Multiple-pulse acquisition OTDR techniques have also been developed to test more complicated configurations, including PON networks and fiber to the home (FTTH) deployments.Ĭontact sales to learn more about VIAVI OTDR Testing Equipment today, or use the OTDR selector tool to find the recommended tool and request an OTDR price quote. These three techniques form a powerful combination for managing fiber cabling networks or utilizing the fiber for Distributed Fiber Optic Sensing.Īlthough originally intended for long haul fiber optic applications, newer generation OTDR tools can also be used to diagnose much shorter cables, such as internal aircraft and enterprise facility cabling such as structured cabling. ![]() Exfo otdr viewer portable#If there is a discrepancy between the terms of the OSS license and the terms of this license, the license terms of the corresponding OSS take precedence.ĭownloading of the software indicates acceptance of the software agreement.An OTDR instrument can be portable or rack-mounted for permanent placement and monitoring of a network with alarms triggered automatically if the fiber is compromised.Īlong with the Rayleigh scattering method used to characterize fiber links, Raman and Brillouin OTDR technologies can also be used to predict breaks, monitor fiber health, and prevent service outages through temperature and strain measurements.
