Current state of the global submarine network
Internet traffic patterns have shifted, and volumes have surged, as the telecom industry addresses the “new normal” where people are increasingly working, learning, and playing from home. Although the global network infrastructure has bent in certain parts of the network, it hasn’t broken. This is a testament to how reliability and availability is in the DNA of our industry and is more important than ever before.
According to TeleGeography, global Internet bandwidth rose last year by 35%, which was a major increase over the previous year's 26% growth. This increase was driven largely in response to the global pandemic and represents the largest single-year increase since 2013. It also raised the most recent four-year CAGR to 29%. Being able to connect with each other, and to machines, has consistently increased in importance, but in 2020, this took on a whole new level of importance related to our social and economic well-being.
Submarine networks are critical infrastructure
The pace of technology innovation in the telecom industry has accelerated over the past decade in response to growing demands related to our increasing affinity for always-on broadband connectivity. Even the once closed and proprietary world of submarine networks has evolved with the advent of Open Cables, programmable coherent modems, ROADMs, active branching units, C+L band, and more recently, open APIs, intelligent data-driven automation, and analytics. Together, these amazing technologies address challenges related to network scalability, availability, and flexibility during “normal” times. They’re even more important today as we’re mandated to increasingly work and play remotely.
Our industry responds to new challenges
Submarine cables operators have actively taken measures and leveraged innovative technologies in direct response to the new work, learn, and play-from-home environment in most parts of the world. What are these measures taken and what new technologies are being leveraged? What does the future look like?
