Revolutionizing Subsea Cable Systems: The Game-changing Impact of Multi-Core Fiber Technology

As Seen On

With the rapid increase of digitalization, our insatiable thirst for bandwidth expands at an alarming pace. Both cloud providers and network operators teeter on the brink of technological evolution, bearing the weight of society’s growing connectivity needs. Thus, in the heart of this digital renaissance comes the introduction of a new champion in the fight for bandwidth: Multi-Core Fiber (MCF) technology.

Our story, significantly, has roots in the depths of the oceans, where traditional subsea cable systems come alive. For many years, these subsea cables have served as arteries, powering the body of the internet. Pump lasers positioned at strategic points along the length of the cables give life to these routes, amplifying optical signals and carrying digital traffic across vast distances with relentless fervor.

Historically, burgeoning bandwidth demands have been met by expanding the number of fibers in these vast underwater cables – a process known as space-division multiplexing (SDM) technology. Yet, like any Herculean task, SDM too has had its share of challenges. The roadblock it now faces is one of scalability. More fibers increase the cable’s outer diameter, leading to weightier cables that require more physical material. This, in turn, complicates both marine operations and routine maintenance, impeding efficiency.

Enter MCF technology—the potential game-changer the subsea industry needed. Google, along with NEC, is pioneering the integration of this technology for the Taiwan-Philippines-U.S. cable system, marking a significant milestone in the subsea cable industry.

Unlike traditional single-core fibers, MCF technology allows for doubling the number of cores in the cladding, carrying more light and information, all within the same fiber strand. This innovation reduces the cost per bit of data, an accolade that makes MCF technology a fascinating solution. Moreover, the technology facilitates quicker manufacturing and maintenance operations due to a reduced number of fibers in comparison to equivalent core implementations via traditional single-core fibers.

Eduardo Mateo, the Director of Technology Strategy at NEC, emphasizes the significance of this first implementation of MCF in submarine networks, stating, “this innovative MCF technology revolutionizes our approach towards addressing the incessant need for increased bandwidth. It’s truly an exciting time in the industry.”

While recently unveiling MCF in a strategic collaboration, Google and NEC have historically joined forces, constantly exploring innovative fiber-optic cable technologies. And with the introduction of MCF, they are reshaping the future. The potential benefits this technology brings to the subsea cable system could drastically revolutionize the supply chain ecosystem.

The revolution of MCF technology within subsea cable systems is already underfoot. As it provides game-changing solutions to bandwidth issues, MCF is set to reshape the very fabric of connectivity. With such an efficient, cost-effective alternative on the table, the horizon looks promising, unfolding a broadband future that ensures our collective digital dreams become a reality.

Up until working with Casey, we had only had poor to mediocre experiences outsourcing work to agencies. Casey & the team at CJ&CO are the exception to the rule.

Communication was beyond great, his understanding of our vision was phenomenal, and instead of needing babysitting like the other agencies we worked with, he was not only completely dependable but also gave us sound suggestions on how to get better results, at the risk of us not needing him for the initial job we requested (absolute gem).

This has truly been the first time we worked with someone outside of our business that quickly grasped our vision, and that I could completely forget about and would still deliver above expectations.

I honestly can't wait to work in many more projects together!
