TL;DR
This paper investigates how legacy 10G channels impact 100G channels in dispersion-managed optical systems, revealing noise effects and management strategies for amplitude and phase noise.
Contribution
It demonstrates the specific noise interactions caused by 10G channels on 100G channels and discusses DSP robustness and guard-band considerations.
Findings
10G channels induce amplitude and phase noise on 100G channels
Amplitude noise can be managed as ASE and NLI noise
DSP robustness influences guard-band requirements
Abstract
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.
