Optical add-drop multiplexers (OADMs) connect two or more network terminals in an optical network to perform wavelength division multiplexing. If a channel in an optical connection between an OADM and a terminal is interrupted for any reason such that the signal in the channel drops, transient effects such as spectral hole burning may occur which impacts neighboring channels. One approach to avoiding such transient effects in channel drop scenarios includes filling in the spectral hole so that neighboring channels are transmitted without any degradation. An OADM includes a broad spectral source, such as an amplified spontaneous emission (ASE) source, and an optical switch that replaces dropped channels with ASE. By providing an automatic mechanism for spectrum filling within the OADM itself in this way, high-capacity optical transmission networks are stable against transient effects even in the presence of channel drops or fiber cuts.
