White Paper CWDM components for 40 G and 100 G Transceivers D-5006 The sampling interval is 0.25 nm with the data taken from the extreme edge of the passband (approximately 3dB down) to generate the highest chirp. The simulation input would use a reference narrow line width laser source (approximately 0.001 nm) and the filter data provided by the filter manufacturer. The output are sets of eye diagrams showing the effect of Group Delay Ripple on the optical signal traveling over 2 and 10 km of SMF 28e fiber. Results The data taken across the 1319.51 nm passband shows no appreciable impairment as seen in the eye diagram from the effect of filter chirp in combination with either the 2 km or the 10 km lengths of SMF28e fiber. The 1319.51 filter was selected because the filter is the farthest away from the zero dispersion null of the SMF 28e fiber and the wavelengths found in this region would experience the greatest chromatic dispersion.
