Abstract
Systems and methods include causing transmission of one or more shaped Amplified Spontaneous Emission (ASE) signals, from an ASE source (), on an optical fiber (); obtaining received spectrum of the one or more shaped ASE signals from an optical receiver () connected to the optical fiber (); and characterizing the optical fiber () based in part on one or more of a nonlinear skirt and a center dip depth in the received spectrum of the one or more shaped ASE signals. The one or more shaped ASE signals can be formed by the ASE source () communicatively coupled to a Wavelength Selective Switch (WSS) () that is configured to shape ASE from the ASE source to form the one or more shaped ASE signals with one or two or multiple peaks and with associated frequency.
