Understanding OTDRs Course

This self-study course from the Fiber Optics Association covers optical time domain electrometers, or OTDRs. Intended for either those already working in fiber optics, or those with some basic familiarity, this course covers an introduction to OTDRs and how they're used in fiber optic testing. The course also covers what OTDRs trace, how they work differently from light sources and power meters or optical loss test sets, how to make measurements, how to set OTDRs correctly, measurement uncertainty, and "gainers" and "ghosts." Practice analyzing tracers with an OTDR simulator is also covered. There are three video lectures in the course, and links to related videos and reference materials are also provided.
