Optical switching technologies have been steadily advancing in recent years and are being deployed in an ever growing range of networks.  Optical switching technologies are attractive due to their data transparency, low-latency and energy efficiency. Emerging applications that could lead to wide scale deployment include scale-out datacenters, optical access networks, space communications, optical sensing, and high-performance computing. Data centers operators in particular see a never-ending growth in demand for high bandwidth reconfigurable services, and are considering the potential of optical switching to provide software-defined virtual connectivity and also to lower costs by increasing utilization and power efficiency through resource disaggregation.

In this panel we will cover recent advances in optical switching technology and development roadmaps along with the driving forces behind current and emerging applications in datacenters and other fields. We will address the key question as to whether optical switching technologies are finally ready for large scale deployments.

Key Topics and Questions to Cover:

1. Current and emerging optical switching applications
2. Driving forces behind deployment of optical switching in networks and datacenters
3. When will optical switches be widely deployed in datacenters and what barriers to entry remain?
4. Where will optical switching technology be in 5 and 10 years?
5. Are very large 10K x 10K optical switches with nanosecond switching speeds really needed?
