Product Brief


Optical time domain reflectometer (OTDR) is an instrument that understands the uniformity, defects, breaks, connector coupling, and other properties of the fiber by analyzing the measurement curve. It is based on the backscattering of light and Fresnel reverse principle. It uses the backscattered light generated when light propagates through the fiber to obtain attenuation information. It can be used to measure fiber attenuation, connector loss, fiber fault point location and understanding The loss distribution of the optical fiber along the length is an indispensable tool in the construction, maintenance and monitoring of optical cables
