| Abstract: | In this paper we report our analysis, simulations, and proof-of-principle experiment on transparent monitoring of relative rise-time using asynchronously sampled amplitude histograms in optical transmission systems. Our method is based on the count in a selected amplitude window between the mark and space levels. We evaluate our method under various amplitude windows and Q-factor values and compare with synchronously sampled eye-diagram based measurements. Our results demonstrate that the 40%-60% amplitude window is generally suitable for system rise-time monitoring purpose without clock information. |
