Hollow-Core Fiber: Three Major Challenges (Part 3) : From T-Bit Transmission To Transoceanic Relay, Three-Year Vision Map And Ultimate Imagination
Oct 10, 2025| Hollow-Core Fiber: Three Major Challenges (Part 3) : From T-Bit Transmission to Transoceanic Relay, Three-Year Vision Map and Ultimate Imagination
Standing at the intersection of technological breakthroughs and the eve of industrialization, we can't help but ask: What role will hollow optical fibers play in the optical communication world three years from now? Is it an upgrade patch for traditional transmission networks or a key to unlocking new application dimensions? The outlook from the forefront paints a broad blueprint for us that far exceeds communication itself.
1.In-depth expansion in the field of communication: Igniting the "AI computing power" engine
In the short term, communication will remain the main battlefield for hollow optical fibers, but their value will be redefined. Industry experts are looking forward to "large-scale use in long-distance transmission networks to transmit T-bit-level rates". The more explosive growth point directly points to the core of today's technological wave - artificial intelligence.
The testing expert stated straightforwardly: "Of course, it's the interconnection of AI DCS, or even the internal connection of AI DCS." " Large AI clusters are almost thirsty for low latency and high bandwidth for internal interconnection. The low latency and high bandwidth characteristics of hollow-core optical fibers precisely provide a physical basis for the pooling of AI computing power and the elimination of communication bottlenecks, and are expected to become the "neural network" within the next-generation ultra-large-scale data centers.
2. Disruptive Scenario: The dream of long-distance transoceanic communication without relays has come true
An industry expert has depicted a more disruptive scenario: "Long-distance unrelayed communication across oceans." This is a comprehensive manifestation of the performance advantages of hollow-core optical fibers: their ultra-low loss enables signal transmission over longer distances, while their hollow structure can withstand much higher incoming power than solid-core optical fibers, effectively overcoming the limitations of nonlinear effects. This means that in the future, optical cables across the Pacific or Atlantic may significantly reduce or even eliminate expensive and difficult-to-maintain submarine Repeaters, greatly enhancing the reliability and economy of the system, which can be regarded as a paradigm revolution in submarine communication.
3. Marching towards the "New Continent" of Sensing and Laser
A more strategic outlook comes from experts at universities and research institutes: "I hope that in three years, the application of hollow-core optical fibers can break through the communication field and penetrate into emerging scenarios such as sensing and lasers."
In the field of sensing: Hollow structures provide an excellent platform for interaction with the gas or liquid to be measured, which can give rise to ultra-high sensitivity gas sensors, biosensors, etc. The application of hollow optical fibers in the field of optical gyroscopes has also made significant breakthroughs in recent years.
In the field of lasers: As an ideal platform for laser transmission and generation, hollow-core fibers can be used to manufacture new types of laser equipment with higher power, better beam quality and more extreme spectral performance.
Expanding into these non-communication fields can not only diversify the risks of a single communication market, but also build a more diverse and healthy industrial ecosystem, opening up unlimited space for the long-term evolution of hollow-core optical fiber technology.
Finally, over a three-year period, the picture of hollow optical fibers will expand from communication backbone networks, AI data centers, transoceanic optical cables all the way to the vast territory of precision sensing and advanced lasers. Its future is not only a linear upgrade of "faster and farther", but also a "cross-border" revolution that may reshape the landscape of multiple high-tech industries. The curtain of this transformation is slowly rising.
