automation and orchestration

Ciena’s V-WAN Hypervisor abstracts and virtualizes cloud backbone network resources

Cloud operating systems request allocation of those resources directly & automatically

No need to understand the details of the underlying network

No manual processes or system “swivel chairs”

Can you play a 4K uncompressed Video from Amsterdam connected through 128 different spans over a distance of more than 4200km through 4 different national networks and one submarine link as a foreign (alien) wave through your competitors infrastructure?

….at a major public event where everybody will see the results? Oh! And at 100G please?

HOW FAR CAN WE GO?

in real systems spectral efficiency is limited by fiber non-linearities a spectral efficiency of 12 bit/s/Hz is conceivable at ~1600 km

requires compensation for intra-channel non-linearitiesmaximum C-band capacity >50 Tb/s (currently 8.8 Tb/s with 100G per channel)
