An Optical Time Domain Reflectometer (OTDR) is an essential device used by fiber optic technicians for validating the continuity and integrity of optical fiber spans along with identifying and locating physical issues like breaks and degradations that negatively affect signal performance. As OTDRs are complex devices that must be configured properly by the user for each test scenario, classroom training is critical for learning and training purposes, ensuring that technicians are taking the most accurate measurements when using in the field network environment.
