Optical Time Domain Reflectometer (OTDR) is a device used in fiber optic networks to measure the characteristics of the fiber such as attenuation, splice losses, and connector losses.

The distance range of an OTDR refers to the range over which the device can accurately measure the optical fiber characteristics. This range is typically specified in kilometers (km) or miles (mi). It indicates the maximum length of the fiber that can be tested by the OTDR while still providing accurate and reliable measurements.
