"Physical Layer Technologies for Flexible/Elastic Optical Networks"

Cartagena, Spain, June 23-27, 2013

Recent research advancements propose new technologies for the Future Network to cope with the high-capacity requirements. “Flexible”, “elastic”, “tunable”, “gridless” or “adaptive” are a few examples of the terms used by the research community to describe solutions that migrate from the fixed WDM optical networks to systems with improved and heterogeneous transmission characteristics. Conventional fixed-grid WDM networking leads to the stranded bandwidth issue, due to the coarse and rigid granularity of the system (that is, the granularity at the wavelength level), where frequently only a small portion of the fully allocated wavelength channel capacity is used.
