Webinar: Side-Stepping Shannon’s Limit With SDM Cables

Written by Jayne Miller | Mar 25, 2019 11:57:00 AM

Even as coherent modem technology continues to innovate, the amount of data that can be carried over today’s networks shows no signs of slowing. 

Despite all this modem magic, we can’t ignore the laws of physics. We’re quickly approaching the Shannon Limit–the maximum information-carrying capacity of a submarine cable optical fiber pair.

What new alternatives are on the horizon to side-step this inevitability? 

One approach—Spatial Division Multiplexing (SDM)—is getting a lot of attention. This new option for building future submarine cables is intended to address ongoing capacity demands.

Join our own Tim Stronge and Ciena's Brian Lavallée on April 3 at 11 am ET for a 30-minute webinar as they discuss:  

  • How many cables will be needed in 10-15 years?
  • What is SDM and how can it be leveraged in submarine cable deployments?
  • What are the technology implications of deploying SDM?
