Hollow-core fiber (HCF) marks a revolutionary upgrade from conventional solid-core optical fiber. Instead of transmitting light through solid silica glass, HCF guides light within an air core. This unique structure delivers unmatched strengths: ultra-low latency, nearly eliminated optical nonlinear effects, high laser damage threshold, and strong immunity to electromagnetic interference.

Once confined to laboratory trials, hollow-core fiber is rapidly moving toward large-scale commercial deployment across multiple high-tech sectors. However, HCF’s delicate microstructure poses strict challenges for fusion splicing. Improper arc energy or inaccurate alignment can easily collapse the hollow core and introduce excessive splice loss. A dedicated hollow-core fiber fusion splicer becomes essential for stable, repeatable splicing results. Today we review major HCF application scenarios and introduce the SHINHO S-23, a purpose-built splicer for hollow-core fiber projects worldwide.

Major Application Fields of Hollow-Core Fiber

1. Ultra-Low-Latency Optical Communication

2. High-Power Laser Delivery

3. High-Precision Optical Sensing & Environmental Monitoring

4. Quantum Photonics & Advanced Scientific Research

Why Dedicated Splicing Equipment Matters for HCF

Standard fusion splicers designed for single-mode or multi-mode fiber cannot satisfy hollow-core fiber requirements. Operators must precisely control arc heat and alignment to avoid core collapse and keep splice loss low. As HCF commercialization accelerates, system integrators, research labs and laser manufacturers are seeking reliable, field-proven HCF splicing tools.
