As state-of-the-art transmission equipment pushes towards higher spectral efficiencies and symbol rates, there is an equally important drive for flexibility in optical networks. In response to this, highly flexible bandwidth allocation, adaptive constellation entropy (or spectral efficiency), and machine learning-based DSP paradigms are all being considered for future network deployments. However, adaptivity increases system and network complexity. Could other solutions be more cost-effective or practical?
In this session, a cross-section of representatives from industry and academia will give their take on the questions of adaptivity and flexibility in future optical networks.
The workshop will be divided into four sections:
• Crystal balling: how to make a deployment decision today based on the next 20 years’ needs?
• Do we need more (or less!) adaptivity in optical networks?
• Capacity without complexity: can we meet capacity demands with better fiber/cables, alone?
• Reality versus fiction in autonomous networks
