Traditional optical networks are over-engineered due to conservative assumptions used in the planning process with regards to module characteristics, system performance, and network fiber infrastructure, and due to the requirement to sustain many years of error/failure-free operation with limited reconfigurations (if any). As a result, typical optical networks operate with high performance margins and underutilized capacity.
However, modern optical networks with flexible ROADMs, highly-configurable transponders and (typically SDN-based) software control may have a shorter circuit life time than traditional fixed optical networks.
Furthermore, the ability to pull performance data on many parameters in a ROADM or transponder every second or even faster enables unprecedented visibility into the optical layer behavior.
As we approach the practical limits of spectral efficiency, one avenue to further increase capacity is to more accurately determine the actual performance of the optical network and operate it at higher capacity with lower margin.
This panel will investigate the new trend for lower margin optical networks. We will start with Network Operator views and then have experts from Industry and academia discuss their challenges and solution proposals.
