Commonly available fiber test and measurement equipment includes optical power meters, light sources, visual fault locators, optical time-domain reflectometers, polarization analyzers, fiber inspection microscopes, and chromatic dispersion analyzers. These devices are used to test fiber optic cables for breaks, faults, and contamination, measure power levels and signal quality, and detect polarization-related issues. The specific type of equipment required will depend on the specific application and testing requirements.
