Real-time tracking numbers will be provided.

Q: How does the AI5PRO compare with previous models or other brands like Inno, Fujikura, and Sumitomo?

The AI5PRO features a six-motor system with 0.5μm high-precision alignment, achieving splice loss comparable to high-end Japanese models but at a more competitive price. Its 3-in-1 holder requires no tools for changing and works with bare fiber, pigtails, drop cables, etc. The built-in 5200mAh battery supports 160 splicing & heating cycles – better than most peer products.

Q: Are there tiered pricing for bulk purchases?

For distributors, engineering companies, and group purchases, we offer competitive tiered pricing. The larger the order quantity, the better the unit price.Please contact our sales team for details.

Q: Are you an official authorized distributor of the Signal Fire brand? Can you provide authorization proof?
