Bandwidth and power consumption are two key factors to be considered for cost-sensitive datacenter applications. As datacenter switch port bandwidths continue scaling to 400Gb/s and beyond, the datacenter network hardware power dissipation is increasing exponentially.  The coming "power crunch" associated with the increased bandwidth will be a major problem for datacenter operators.  

  • What are the most effective solutions to mitigate the increasing power problem?

  • Are there novel optics, for example novel high speed directly modulated lasers (DMLs) or Silicon Photonics technology that reduce power consumption?

  • How can we leverage DSP and spectrally efficient modulation techniques, e.g. is it feasible to drive analog optics modules directly from the host ASIC, similar to the 10G SFP+ solution?

  • Can novel multi-mode or multi-core fibers provide a new approach?

  • What is the role of FEC?

  • Is there room for optimizing the FEC triple tradeoff in gain, latency, power to achieve an overall lowest power system design?

  • How can we leverage the mature DWDM technology for datacenter applications?

  • Are there novel topologies or network architectures that can radically reduce power consumption?

  • Is there a role for ROADMs, optical switches, or coherent technology inside the datacenter? Clearly a holistic system view is necessary for finding the optimal solution.

This workshop will bring together experts from optics, fiber, SerDes design, DSP/FEC, and network architecture for an interdisciplinary discussion.
