TL;DR: In this article, the relationship between group delay ripple and eye closure penalty was analyzed and two metrics that parameterise signal degradation due to optical filter group delays ripple were developed to provide an upper and lower limit to the eye closures penalty applicable over a wide range of group delays.

TL;DR: In this paper, the effects of the electrical bandwidth and the DC extinction ratio of Mach-Zehnder (MZ) modulators have been investigated for transmission performances, and the calculated eye-diagrams and BER characteristics of the proposed schemes have similar characteristics at 160 km transmission, compared to the conventional duobinary scheme.
