Optical Time Domain Reflectometry (OTDR)

Optical Time Domain Reflectometry (OTDR) is a technique used to analyze fiber optic cables by sending pulses of light into the fiber and measuring the reflected signals. As these pulses travel, some light reflects back at points where the fiber has imperfections, joins, or damage. By measuring the time and strength of the reflected light, technicians can create a detailed map of the fiber’s condition, identifying faults, breaks, or weak spots. OTDR is essential for maintenance and troubleshooting, ensuring the integrity and performance of fiber optic networks.
