Listen Later

What were the big cable headlines of this year, and what do you need to know about transport networks in 2026? To find out, we're kickstarting our three-episode review of What to Know in the New Year.

Joining us for this submarine and terrestrial infrastructure review are friends of the pod Lane Burdette and Paul Brodsky.

In this episode of the TeleGeography Explains the Internet podcast, these experts address:

  • How much of a submarine cable boom was there in 2025 and will that continue into 2026?
  • Where are new builds located around the world and why?
  • Will all this new capacity lead to over-supply?
  • Are fiber developers having to chase AI data centers into novel locations?
  • How are terrestrial builds related to submarine cable bottlenecks?
