In a new video interview with Hot Telecom's Isabelle Paradis, Anders Ljung, Business Manager Submarine Solutions at Hexatronic, shares insights into how unrepeatered subsea fiber systems are expanding beyond telecom and into the energy sector. In light of recent events with cable breaks and sabotage, the conversation also covers the urgent topic of subsea cable security. With 95 percent of the world's internet traffic flowing through subsea cables, protecting this critical infrastructure is essential. Go ahead and watch the video to learn how we can build safer networks together!
The market is shifting from telecom to energy
The global subsea cable market is changing. Subsea fiber cables have long played a vital role in telecom, but today they are becoming increasingly important in the energy sector. Offshore wind farms, interconnects, and utility networks rely on fiber optics for data transmission, operational control, and real-time monitoring. This shift is creating new demands for flexibility, speed, and durability. As Anders Ljung highlights in the interview, many still don’t realize how central subsea fiber is to enabling the energy transition. With growing awareness, the market is expected to expand significantly over the next decade.
In the next 10 years, we'll see a big boom in unrepeatered subsea cables, especially in energy applications.

Protecting the backbone of the internet
Subsea cables carry most of the world's internet traffic, but remain vulnerable to external threats. From accidental anchor damage to deliberate sabotage, the risks are real. Anders highlights the importance of route diversity, armoring, and burial to improve resilience. But the most effective strategy is simple: more cables.
Unrepeatered systems, like those Hexatronic specializes in, offer unique advantages. They're easier to repair, faster to deploy, and well-suited for regional and energy-related applications. By utilizing sensing technologies, from temperature to acoustic monitoring, threats can be detected before damage occurs.
Building safer networks together
At Hexatronic, we focus exclusively on unrepeatered subsea fiber systems. That makes us agile, responsive, and ready to support customers with fast turnaround and tailored solutions. Whether it's spare cable availability, robust armoring, or collaboration with sensing partners such as the Hexatronic Group company Proximion, we're committed to helping our customers build safer, more resilient networks.
Protecting global connectivity is a shared responsibility. It requires collaboration across industries, governments, and technology providers. We're proud to be part of that effort—and ready to help our customers meet the challenges ahead.
