Hollow-Core Fiber: Three Major Challenges (Part 2) | Price, Standard, and Ecosystem
Oct 09, 2025| Hollow-Core Fiber: Three Major Challenges (Part 2) | Price, Standard, and Ecosystem: Breaking Through the "Non-technical" Triple Door of the Laboratory
When the dawn of technology breaks, the clarion call for industrialization is sounded. On the stage of hollow-core fiber (HCF), technology is no longer the sole protagonist. With capital pouring in and industry giants making strategic moves, a commercial contest involving market entry, cost competition, and ecosystem development is unfolding. Beyond the technical challenges, what are the more complex "non-technical" barriers hindering the large-scale commercial use of hollow-core fiber?
1. Strategic Breakthrough: Selecting the 'Optimal' Scenario for Value Demonstration
The choice of industrialization path is crucial to success. An expert from a university research institute offered clear strategic advice: "From the perspective of quickly creating value, I believe hollow-core fiber can be prioritized for promotion in the Data Center Interconnect (DCI) field."
Why DCI? First, this is a scenario with extreme demands for low latency. Hollow-core fiber can reduce transmission latency by about 30% compared to traditional single-mode fiber, providing an immediate and clear advantage. Second, DCI link distances are relatively short, making the stringent requirements for long-term fiber reliability slightly lower than those for thousand-kilometer backbone networks, thus reducing the initial barriers to adoption. As a testing expert stated: "It essentially boils down to whether a 30% reduction in latency provides sufficient attraction for high-value services." In high-end DCI markets like finance and cloud computing, this advantage can be translated into pricing power. Establishing a foothold in a high-value, highly sensitive niche market first to create a demonstration effect is key to breaking the deadlock.
2. Core Obstacle: Cost Skepticism and the "Chicken-or-Egg" Cycle
However, industry experts also pointed out the most practical obstacle: "Skepticism towards hollow-core fiber and an inability to accept its current high price." This creates a typical industrialization cycle: high prices stem from small-batch production and the amortization of high R&D costs; yet, to expand scale and reduce costs, sufficient market demand is required to drive it.
The solution lies in moving beyond the cost-performance thinking applied to traditional fibers and focusing on its irreplaceable performance value. Industry experts indicated that application in long-haul transmission networks requires waiting for standard finalization and price reduction, but "the application scenario in data center interconnection is more aggressive." This means the early market must be led by "lighthouse users" who are extremely sensitive to performance and have a certain tolerance for cost.
3. Ecosystem Building: Can the Standardization Process be "Sped Up"?
Standards are the cornerstone of industrial maturity. A testing expert provided an optimistic perspective: unlike single-mode fiber standards which took 16 years to mature, "HCF was born in an era of highly developed optical communications, so standardization efforts should be more optimistic."
The early establishment of standards will greatly promote the interoperability of fiber interfaces, equipment, and modules, reducing R&D uncertainty across the ecosystem and thereby accelerating cost reduction. This requires all parties in the industry chain to abandon going it alone and move towards openness and cooperation in advance.
The core point is that the industrialization of hollow-core fiber is a contest of strategy, patience, and ecological wisdom. It does not need to win on all fronts simultaneously but must concentrate its efforts to achieve an initial victory in strategic strongholds like DCI. Once the first large-scale application case is successfully implemented, forming a closed value loop, it can effectively counter cost skepticism, drive the acceleration of standards, and ultimately leverage the entire industry flywheel into a virtuous cycle of "expanding application → decreasing cost → thriving ecosystem."
Meanwhile, the IFOC 2025 forum also conveyed a strong signal: the industrialization of hollow-core fiber is no longer just a concept. Although cost remains a focal point of discussion, the path of first proving irreplaceability through high-value scenarios and then feeding back into cost reduction for the industry chain has basically become the mainstream consensus among participants.
