Fair comparison of complexity between a multi-band CAP and DMT for data center interconnects

Wei, Jinlong, Sánchez, Christian and Giacoumidis, Elias (2017). Fair comparison of complexity between a multi-band CAP and DMT for data center interconnects. Optics Letters, 42 (19),


We present the first known detailed analysis and fair comparison of complexity of 56-Gb/s Multi-band CAP and DMT over 80-km DCF-free SMF links based on intensity modulation and direct detection (IMDD) for data center interconnects. We show that the matched FIR filters and (I)FFT take the majority of the complexity of the Multi-band CAP and DMT, respectively. Choice of the multi-band CAP sub-band count and the DMT (I)FFT size makes significant impact to system complexity or performance and trade-off must be considered.
