Product Introduction

The TFN M1 Four-Motor Fully Automatic Fiber Optic Fusion Splicer is a high-performance, field-deployable splicing machine designed for telecom engineers, network installers, and fiber optic technicians. It features a four-motor alignment system for ultra-low loss splicing, with an average loss of just 0.02dB for single-mode fibers. Equipped with a 4.3-inch touchscreen and dual cameras for real-time monitoring, it ensures precision and ease of use. The rugged, rainproof and dustproof design makes it ideal for outdoor and harsh environments. With a 5200mAh battery supporting up to 240 splicing cycles and a versatile three-in-one fiber clamp, the M1 streamlines workflow and enhances productivity for FTTH, 5G deployments, and security surveillance projects.

Key Selling Points (Bullet Points)

-High Precision & Ultra-Low Loss Fusion Splicing 

Our four-motor alignment system ensures consistent and reliable fusion splices with average losses as low as 0.02dB for single-mode and 0.01dB for multi-mode fibers. This results in stronger signal integrity, reduced network downtime, and superior performance in long-haul and high-speed fiber networks.

-Fast & Efficient Splicing & Heating 

With a standard splicing time of just 7 seconds (6 seconds in FAST mode) and an 18-second heating cycle, the M1 significantly reduces project completion time. The adjustable heating duration (10–900 seconds) and V-shaped heating mold provide uniform heat distribution for reliable sleeve shrinking.

-All-in-One Triple-Function Fiber Clamp 

No more switching clamps! Our three-in-one fixture supports 0.25mm, 3.0mm, and flat indoor cables, making it compatible with pigtails, drop cables, and patch cords. This simplifies fieldwork and reduces equipment setup time.

-Long-Lasting Battery & Portable Design 

Powered by a 5200mAh lithium battery, the M1 supports approximately 240 complete splice + heat cycles on a single charge. Its compact and rugged body, complete with a rubber protective case, is built for portability and durability in outdoor conditions.

-Smart Operation & 2-Year Warranty 

Featuring a 4.3-inch touchscreen, dual-camera real-time monitoring, 41 preset programs, and storage for 2000 splice records. Backed by a 2-year warranty with online support and loaner unit service, ensuring peace of mind and uninterrupted operations.

Product Features

Feature 1: High-Speed Fusion & Intelligent Heating System

The TFN M1 integrates a four-motor alignment mechanism and a V-shaped heating mold to deliver rapid and uniform heating in just 18 seconds. This system ensures consistent sleeve shrinking and minimizes splice failure, ideal for high-volume FTTH and 5G network deployments. The adjustable heating time allows customization for different environmental conditions, enhancing reliability in both indoor and outdoor installations.

Feature 2: Three-in-One Fiber Clamp & Precision Cleaver

Our proprietary triple-function clamp accommodates multiple fiber types without tool changes,

streamlining workflow and reducing clutter. Paired with the included professional fiber cleaver, it ensures clean, angled cuts for low-loss splicing. This combination is perfect for contractors handling diverse cable types in hybrid network environments.

Feature 3: 5200mAh Extended Battery & Field Readiness

With a high-capacity 5200mAh lithium battery, the M1 supports up to 240 complete splicing and heating cycles—enough for full-day field operations without recharge. The battery features real-time monitoring and can be charged via AC or vehicle DC input, making it an essential tool for remote site work and emergency repairs.
