OTDR (The optical time domain reflectometer): The reflector in the optical time domain can verify the fiber insertion loss in fiber optic cables, measure the length and detect the cable break, if any, and provide an analysis report by characterizing the fiber optic cable.
Portable Power Meters & Light Sources
It is a device used to measure the power in an optical signal called an optical power meter (OPM). The term generally refers to a device used to test average power in fiber optic systems. Other general purpose light power meters are often referred to as radiometers, photometers, laser power meters, light meters or lux meters.
