A new edge detector for CMI optical fiber transmission with improved jitter tolerance
Yong Huat Chew, T.T. Tjhung · Journal of Lightwave Technology · 1993
An edge detecting scheme for coded mark inversion (CMI) line codes which can reject wrong slot errors is proposed. This scheme looks at data transitions over one-and-a-half symbol durations and makes a binary decision based on the most likely transition pattern. An analysis and measurement results for the bit-error-rate performance of this scheme over an optical fiber link which show improvements in the detector tolerance against symbol timing jitters are presented.>
