This Proposed Policy Could Impact The International Cable Community. Here’s How.

Cable breaks occur more often than you might think. Research presented in this paper counted 14 different cable failures in U.S. territorial waters or exclusive economic zone between 2008 and 2012.

We rarely hear about such cable failures because we currently enjoy two built-in mechanisms that mitigate the effects of a break: a robust, redundant set of networks allowing traffic re-routes when a cable fails, and a nimble fleet of cable repair ships that can respond quickly to problems. Changes to the interpretation of the Jones Act may impair the latter mechanism.

We went 12 years without building a new cable in the Atlantic. In the last two years we've seen two builds, another announced, and more planned.

This might be why our VP of Research Tim Stronge recently asked a group of PTC 2017 attendees if we're in a submarine cable bubble.

Wouldn't it be Nice if Your Network Told You When a Cable Was About to Fail?

Brian Lavellée, Director of Portfolio Marketing at Ciena, posed this question to webinar-watchers last Wednesday. How great would it be if you got an advanced warning prior to a submarine cable going down?

Brian was joined by TeleGeography Senior Analyst Brianna Boudreau to tackle this idea and others about the cable business.
