Abstract
The key design approaches and results in the field of compensation of optical impairment distortion by
electronic means, as an outcome of the studies and research innovations developed within the joint project on
mitigation of optical transmission impairments by electronic means work group of the ePhoton/ONeþ European
project are presented. The research topics addressed are related to chromatic and polarisation mode dispersion,
with particular reference to feed-forward/decision-feedback equaliser and maximum-likelihood sequence
estimation-based equalisers as well as pre-distortion schemes. Additionally, the use of electronic
compensation in metro/access applications is examined with reference to studies related to the performance
enhancement of directly modulated laser transmitters, the compensation of the square-law characteristics of
receivers and the equalisation of multi-level format schemes.
