Power Meter

A device that measures the power of an optical signal in a fiber-optic system. When combined with an optical light source (OLS), it becomes an optical loss test set (OLTS) and can measure end-to-end attenuation. It can also be used with a visual fault locator (VFL). By combining various models, specific test setups can be created.
