OTDR (Optical Time Domain Reflectometer) is a device used to test and characterize optical fiber networks. OTDR can identify and locate specific events (such as fiber breaks, splices, or connectors) along the length of the fiber. This is particularly useful in troubleshooting and maintenance. OTDR can also calculate the total optical loss of the fiber segment under test, helping identify areas where signal loss is higher than expected.

Applications of OTDR:

• Fiber Installation
• Troubleshooting and Maintenance
• Network Performance Monitoring
• Pre-Deployment Testing
• Fiber Certification
