Attenuation profile, or spectral attenuation profile, testing is an optical fiber characterization test that verifies gain-flattened network components. The AP solution consists of an optical spectrum analyzer, a broadband source (or a broadband power meter), and a tunable light source. Figure 37.

OTDR (Optical Time Domain Reflectometer) A test instrument that analyzes the light loss in an optical fiber. Used to find faults, splices and bends in the line, it works by sending out a light pulse and measuring its reflection. Such devices can measure fiber lines that are longer than 150 miles.
