MT-8631 High Quality Mini Handheld Fiber Optical Power Meter SC/ST/FC/LC Connector Fiber Optic Light Source
OTDR is a precision photoelectric integrated instrument made of Rayleigh scattering and Fresnel reflection backscattering when light is transmitted in an optical fiber. It is widely used in the maintenance and construction of optical cable lines. Among them, measurements such as fiber length, attenuation of optical fiber transmission, joint attenuation, and fault location can be performed.
