OTDR test (Optical Time-Domain Reflectometer test)

An OTDR test (Optical Time-Domain Reflectometer test) involves sending a short pulse of light into an optical fiber and measuring the light that is reflected back to the instrument. The test provides a detailed profile of the fiber’s characteristics by capturing:

Reflections: From faults, splices, and connectors, which indicate the locations and types of issues along the fiber

Losses: In signal strength that occur at different points, helping to assess the fiber’s performance.

Distance Measurements: To determine the location of events such as breaks or bends in the fiber.

This test is crucial for troubleshooting, maintaining, and verifying the quality of optical fiber networks.
