Optical Frequency Domain Reflectometry

Optical Frequency Domain Reflectometry (OFDR) is a technique used to detect and locate faults or irregularities along an optical fiber. It works by sending a finely tuned light signal through the fiber and measuring how the light reflects back at different points. Variations in the reflections reveal the position and nature of any issues, such as cracks or breaks. OFDR provides high-resolution, real-time insights into the condition of fiber networks, making it valuable for maintenance, quality assurance, and ensuring reliable communication systems.
