The Flexible Grid has created a lot of excitement in the industry. It promises a large degree of freedom over the usage of optical spectrum, and as a result the bulk of new ROADM deployments today are Flexible Grid capable, if not enabled. It’s a sort of insurance policy which enables the photonic network to be future proof for any spectral width of transceiver which may be developed. But with the vast possibilities of flexibility come challenges in deployment complexity which must be balanced against the actual benefit in terms of things like spectral efficiency and overall cost of ownership. This panel considers optical network deployments based on flex-grid technologies including the impacts on software models, the relationship to flexible rate transceivers and challenges of network control and management.
