Workshop Description

Conventional fixed-grid WDM networking leads to the stranded bandwidth issue, due to the coarse and rigid granularity of the system where frequently only a small portion of the allocated wavelength channel capacity is used. Indeed core networks are fast approaching the fundamental spectral efficiency limits of single-mode fibres and the capacity growth potential of conventional WDM networks is not sufficient to cope with this issue. Recent technology innovations promise a capacity increase in two dimensions. First, efforts targeted purely the frequency and the signal encoding domains, in an effort to increase the spectral density in fiber links. These efforts led eventually to the definition of the spectral flexible/elastic optical networks utilizing the so-called super-channel approach together with spectrally flexible/elastic multiplexing schemes and advanced modulation formats. More recently, the use of the spatial domain was proposed as the evident solution to extend the capacity of optical communication systems. To this aim, significant research efforts have focused on the development of few-mode fibers (FMF) and multi-core fibers (MCF) so as to enable the so-called space division multiplexed (SDM) systems. The aforementioned technology enablers allow the scientific community to pursue the development of innovative, optical network solutions introducing on one hand a) the flexibility in the spectrum allocation of channels via flex-grid and super-channel technologies, and on the other b) the spatial multiplexing dimension when designing future transport networks.
