Recent theoretical research has indicated that we might soon reach a “capacity crunch”, as the limits of conventional single mode fiber transmission systems are approached. While technologies such as spatial diversity, ultra-broadband Raman amplification, optical and digital nonlinearity compensation have been proposed, none has yet demonstrated an ability to overcome these limitations in practical systems. This workshop will examine the conflicts and opportunities that are emerging in optical transmission systems in this context. Key questions will include:

  • What are the causes of the theoretical and practical capacity limits?

  • How and when will the coming capacity limitations arrive considering the various applications from submarine to metro networks?

  • What solutions have been proposed, and how will they address the problems? 

  • Will the reduction of cost per bit continue by economic solutions such as photonic integration after we reach the “capacity crunch”?
