In recent years, explosively increasing data traffic has been boosting the continuous demand of high speed optical interconnection inside or among data centers, high performance computers and even consumer electronics. To pursue the improved interconnection performance of capacity, energy efficiency and simplicity, effective approaches are demonstrated including particularly advanced digital signal processing (DSP) methods. In this paper, we present a review about the enabling adaptive DSP methods for optical interconnection applications, and a detailed summary of our recent and ongoing works in this field. In brief, our works focus on dealing with the specific issues for short-reach interconnection scenarios with adaptive operation, including signal-to-noise-ratio (SNR) limitation, level nonlinearity distortion, energy efficiency consideration and the decision precision.

Key words: optical interconnection, digital signal processing, advanced modulation formats
