Query: Observing the Effects of Legacy 10G on 100G Channels in Dispersion
  Managed Optical Systems   We show that 10G channels generate both amplitude and phase noise on 100G
channels. Amplitude noise can be managed as the ASE and NLI noise, while the
DSP robustness to the phase noise sets the guard-band.
