This is a quick reference guide on the OSA20 optical fiber amplifier mode, which introduces the noise of optical amplifiers and analysis methods
The document provides step-by-step instructions for launching the Optical Fiber Amplifier (OFA) mode on the EXFO OSA20. It details the process of defining scan settings and analysis parameters, such as sensitivity and filtering width, before running a test.
The OSA20 analyzes optical amplifiers to measure key parameters such as gain, OSNR, and noise.
First, acquire a reference trace of the non-amplified signal, then perform a second scan with the amplifier turned on.
