Subsea transmission capacity is growing at a dramatic rate – with analyst firm Telegeography forecasting a compound growth rate of 46% between 2017 and 2024. Much of this demand is driven by Internet content providers (ICPs). On Transatlantic routes, for example, ICP demand exceeded Internet bandwidth for the first time in 2014, and in 2017, ICP bandwidth accounted for the majority of overall international bandwidth usage.

Extracting the maximum capacity from trans-oceanic cables is, therefore, paramount in importance. This webinar tells the story of the world's first transatlantic transmission using 16QAM modulation across the entire C-Band spectrum, with production equipment and commercial transmission margins.

We look at the following issues:

  • Why is ICP subsea demand growing so quickly?
  • What are the technologies used to achieve successful 16QAM transmission over this distance?
  • How much capacity can we extract from subsea cables, and what is the next miracle technology?
