With the recent advances in digital signal processing (DSP), coherent detection is currently living its second life in the world of fiber-optics. First generation transponders using coherent detection are coming to the market, and a significant amount of research is being invested in this area. With the rise of digital signal processing as an integral part of optical communication systems, most of the complexity is shifted from the optical/analogue to the electrical/digital domain. This will fundamentally change the way we should design our systems. At the same time, new generations of WDM systems continue to increase the maximum capacity; either by reducing channel spacing or by increasing bit rates. This requires the use of state-of-the-art forward error correction (FEC) coding and de-coding in order to improve system margins and realize transmission over long-haul distances. In next-generation optical transmission systems, the design of DSP algorithms and FEC coding & decoding will most likely require acombined approach. This will give rise to a new level of complexity in algorithm design and implementation challenges that will be a major challenge for both industry and the research community. In this workshop we will discuss DSP algorithms, FEC coding & decoding, as well as their mutual interaction in high-capacity long-haul optical transmission systems. The workshop will specifically address the implementation challenges that arise in such complex mixed-signal chip
