Diving into the world of submarine cable systems, I’m thrilled to sit down with Vladislav Zaimov, a seasoned telecommunications specialist with deep expertise in enterprise networks and risk management of vulnerable systems. With years of experience navigating the complexities of global connectivity, Vladislav offers unparalleled insights into the latest advancements in this field. Today, we’re exploring SoftBank’s ambitious Candle subsea cable project, a groundbreaking initiative set to transform digital infrastructure across Asia. Our conversation touches on the project’s significance, its technical innovations, the growing demand for international connectivity, and its potential to reshape economic opportunities in the region. Let’s get started.
Can you give us an overview of what the Candle subsea cable system is and why it’s such a big deal?
Absolutely, Andrew. The Candle subsea cable system is a new underwater telecommunications network being developed by SoftBank, stretching about 8,000 kilometers to connect Japan and Singapore, with additional links to Taiwan, the Philippines, Indonesia, and Malaysia. It’s a big deal because it’s designed to meet the skyrocketing demand for high-speed, reliable internet across Asia, driven by technologies like AI and IoT. With its advanced setup, it’s poised to become a cornerstone of next-generation digital infrastructure in the region.
What inspired SoftBank to take on a project of this scale connecting Japan and Singapore?
The primary motivation comes from the urgent need for enhanced international connectivity in Asia. As digital transformation accelerates, especially with the rise of data-heavy applications like generative AI, there’s a pressing demand for faster, more robust networks. Japan and Singapore are key digital hubs, and linking them directly, along with other countries in between, creates a vital corridor for data flow, supporting everything from business operations to personal communications.
How does the Candle cable stand out compared to other subsea cables already in the Asia-Pacific region?
One of the standout features of Candle is its configuration. Most existing cables in the region have 16 to 20 fiber pairs, but Candle is being built with 24 pairs. That means it can handle a much higher volume of data with lower latency, which is critical for modern applications. It’s not just about capacity, though—it’s also about improving network diversity and resilience, ensuring there are fewer bottlenecks or single points of failure in the region’s internet infrastructure.
Can you break down what it means to have 24 fiber pairs in simple terms for those unfamiliar with the technology?
Sure, think of a fiber pair as a two-lane highway for data—one lane sends information, and the other receives it. Each pair consists of two optical fibers, so 24 pairs mean 48 individual fibers bundled in the cable. More pairs translate to more highways, allowing a massive amount of data to travel simultaneously without congestion. It’s like upgrading from a narrow road to a multi-lane expressway, making everything faster and more efficient.
What kind of real-world impact will this increased capacity and lower latency have on internet users in the region?
For everyday users, it means smoother, faster internet experiences—whether you’re streaming high-definition content, joining video calls, or using cloud-based apps, there’ll be less lag and fewer interruptions. For businesses, especially those relying on AI or real-time data processing, it’s a game-changer, enabling quicker decision-making and more reliable services. Overall, it supports the digital economy by ensuring the infrastructure can keep up with growing demands across Asia-Pacific.
With the project slated to be operational in 2028, what challenges might SoftBank face in sticking to that timeline?
Building a subsea cable of this magnitude is incredibly complex. Laying 8,000 kilometers of cable underwater involves navigating rough seabeds, securing permits across multiple countries, and dealing with environmental considerations. Then there’s the coordination with partners and suppliers to ensure everything aligns. Delays could come from unforeseen technical issues, geopolitical tensions, or even natural disasters disrupting construction. It’s a tight timeline, but with careful planning, it’s achievable.
What’s driving the surge in demand for international connectivity across Asia, especially with technologies like AI and IoT?
The explosion of data-intensive technologies is the main driver. AI, especially generative models, requires massive amounts of data to be processed and transferred in real time, often across borders. Similarly, IoT—or the Internet of Things—connects billions of devices, from smart homes to industrial sensors, all needing constant, reliable internet. As more people and businesses in Asia adopt these technologies, the need for robust, high-capacity networks like Candle becomes critical to avoid slowdowns or outages.
How does the Candle system fit into SoftBank’s broader vision for next-generation infrastructure?
SoftBank sees Candle as a key piece of a larger puzzle. They’re not just building one cable; they’re creating an interconnected network of subsea systems—like Jupiter, ADC, and E2A—that link Asia to the US and other regions. Candle enhances this by strengthening intra-Asian connectivity, ensuring Japan remains a digital gateway for the continent. It’s about building a resilient, future-proof infrastructure that can handle tomorrow’s demands while supporting today’s growth.
In what ways do you think this project will contribute to digital inclusion for people in the connected countries?
Digital inclusion is about ensuring everyone has access to the internet and the opportunities it brings. By connecting countries like Indonesia, Malaysia, and the Philippines to major hubs like Japan and Singapore, Candle helps bridge the digital divide. It can bring better access to online education, telemedicine, and e-commerce to underserved areas, empowering communities with tools to improve their lives. It’s not just about laying a cable—it’s about opening doors to the digital world for millions.
Looking ahead, what’s your forecast for the future of subsea cable systems in meeting Asia’s connectivity needs?
I believe we’re just at the beginning of a massive expansion in subsea cable infrastructure across Asia. With data consumption growing exponentially, projects like Candle are critical, but they won’t be the last. We’ll likely see more cables with even higher capacities and innovative designs to handle emerging technologies. The focus will also shift toward redundancy and resilience, ensuring networks can withstand disruptions. Asia’s digital future depends on these investments, and I’m optimistic we’ll see continued collaboration and innovation to keep pace with demand.
