Abstract
The present invention relates to test equipment (e.g. TBERD 8000) with two or more Tunable Lasers (TL) for testing the complete spectrum of a DWDM system. Diagnostic software is used to stepwise tune a TL to a specific wavelength under test and simultaneously insert one or more distortion wavelengths while executing bit error and impairment tests on the wavelength under test. Information from these tests is correlated to create a combined DWDM network test report.
