The evolution of communication infrastructure is at a crossroads, with hollow-core fiber (HCF) challenging the decades-long dominance of traditional glass-core fiber . While HCF promises revolutionary improvements in speed and efficiency, traditional fiber remains entrenched due to its proven reliability and cost-effectiveness (1). This article examines both technologies to determine their roles in shaping the future of global connectivity.

1. Technical Comparison: Hollow-Core vs. Traditional Fiber
1.1 Signal Speed and Latency
Hollow-core fiber transmits light through air, reducing latency by 30% compared to traditional glass-core fibers. Light travels at 3.46 µs/km in HCF versus 5 µs/km in glass fibers (3). This makes HCF ideal for real-time applications like autonomous vehicles and financial trading systems, where milliseconds matter (4).
1.2 Signal Loss and Attenuation
Traditional fibers suffer from attenuation due to material absorption and scattering, with losses around 0.14 dB/km (5). HCF, however, achieves <0.1 dB/km attenuation in lab tests, enabling longer-distance transmission without repeaters (6).
1.3 Nonlinear Effects
Glass-core fibers are prone to nonlinear distortions (e.g., Kerr effect) at high power levels. HCF’s air core minimizes these effects, making it a better fit for quantum communication and terabit-level systems (7).
2. Applications: Where Each Technology Excels
2.1 Traditional Fiber
Traditional fiber dominates in:
- Backbone Networks : Connecting cities and data centers due to its maturity and cost-effectiveness (8).
- FTTH Deployments : Affordable solutions for residential broadband (9).
2.2 Hollow-Core Fiber
HCF excels in:
- 5G Fronthaul : Reducing latency for real-time IoT applications (10).
- Quantum Communication : Secure key distribution for defense and finance (11).
Case Study
A 2024 European telecom project used HCF to cut latency by 30% , improving autonomous vehicle response times in urban areas (1).
3. Challenges for Hollow-Core Fiber
3.1 Manufacturing Costs
Producing HCF with precise air-core structures is expensive. For example, current HCF production costs are 20% higher than traditional fiber (12).
3.2 Compatibility
HCF requires hybrid systems to integrate with legacy glass-core infrastructure, adding complexity (13).
3.3 Market Adoption
Traditional fiber’s entrenched position slows HCF adoption. Industry-wide standardization is critical for broader use (14).
4. Future Trends and Projections
4.1 Hybrid Networks
Experts predict a blend of HCF and traditional fiber. HCF will handle latency-sensitive tasks, while traditional fiber supports legacy systems (15).
4.2 Sustainability
HCF’s lower energy consumption aligns with global sustainability goals.
5. Which Technology Will Dominate?
5.1 Short-Term Outlook
Traditional fiber will remain dominant in most applications due to lower costs. HCF will target niche markets like quantum computing (16).
5.2 Long-Term Potential
By 2030, HCF could replace traditional fiber in 6G networks and smart cities, where ultra-low latency is non-negotiable (17).
Conclusion
Hollow-core fiber offers transformative advantages, but traditional fiber’s cost-effectiveness ensures its continued relevance. The future will likely involve hybrid systems leveraging the strengths of both technologies (18).
