Leaving the current 4th generation of mobile communications behind, 5G will represent a disruptive paradigm shift integrating access networks, ultra-high capacity access/metro/core optical networks and intra-datacentre ...

We quantify the network capacity scaling from 7 to 30 spatial channels. While multifiber provides a 5x capacity increase, MCF limits it to 4x and 2x in national and continental backbone networks, respectively.

To effectively keep pace with the global IP traffic growth forecasted in the years to come, flex-grid over multi-core fiber (MCF) networks can bring superior spectrum utilization flexibility, as well as bandwidth scalability ...

Experimental investigations show that maximum likelihood sequence estimation (MLSE) in a 10.7 Gb/s non return-to-zero system improves by 60-70% the tolerance to first-order polarization mode dispersion (PMD), even in the ...

Future optical core networks realizing Flex-Grid and Space Division Multiplexing (Flex-Grid/SDM) will be key to effectively cope with the rapid growth of the Internet traffic, thanks to their superior capacity and spectrum ...

A dynamical simulation model for three-section DBR laser is extended to analyse the thermal effect under continuous tuning. A new method to compensate the thermal drifts is implemented, and we have simulated a nonintrusive ...

We demonstrate a nonlinear function after the photodetector that linearizes dispersion-limited IM-DD systems, enhancing the performance of linear electronic equalization. Results showed a clear improvement in terms of ...
