Abstract
A test apparatus includes a broadband noise source, a test station, and a spectrum analyzer. A method using the test apparatus to measure the spectral gain of an erbium doped fiber amplifier (EDFA) under test includes steps of providing an optical signal from a broadband noise source to an input of the EDFA under test, measuring a power at a test wavelength at an output of the EDFA under test, adjusting the test wavelength, and repeating the steps of measuring and adjusting for a predetermined number of times.
