The TFN S7 fiber fusion splicer is a high-performance splicing machine designed for long-haul trunk lines, provincial backbone networks, and base station emergency repairs. Equipped with a six-motor core alignment system, it ensures ultra-low splicing loss and fast splicing speed. It is an ideal choice for telecom engineers, field technicians, and network maintenance teams.
Product Features
1. Ultra-Fast & High-Precision Splicing
The S7 features a six-motor core alignment system designed for long-distance trunk lines, delivering consistent splicing loss as low as 0.01 dB. With a splicing time of 6 seconds in FAST mode, it improves work efficiency.
2. Intuitive Interface is Easy to Use
S7 is equipped with a 5-inch color touchscreen and physical buttons, allowing easy and efficient operation.
3. Long-Lasting Battery with Real-Time Monitoring
Powered by a 5200 mAh pluggable lithium battery, the S7 supports over 240 splicing and heating cycles. The built-in power monitoring system displays real-time battery status, preventing unexpected shutdowns during critical field operations.
4. Universal Three-in-One Clamp
The integrated clamp supports bare fiber, pigtail fiber, and skinned wire without requiring accessory changes. Compatible with fiber diameters from 0.25 mm to 3.0 mm and flat indoor cables, it reduces the need for additional tools and simplifies on-site workflow.
5. Rugged & Reliable Design
Built with a rainproof, dustproof, drop-resistant housing, and backed by a 3-year warranty and lifetime technical support, the S7 is engineered for durability in harsh environments, such as base station repairs, outdoor installations, and emergency maintenance scenarios.

The fusion splicer features an X/Y dual-axis fiber observation system, providing fiber views from two perpendicular directions to accurately detect core offset in both axes. This ensures precise three-dimensional core alignment before fusion, reduces alignment errors, and helps achieve consistently low splice loss.
Automated Fusion Splicing Process:
Fiber positioning → X/Y core alignment → Pre-fusion arc → Fusion splicing
