Signal Fire AI-5 PRO Professional Optical Fiber Fusion Splicer

The Signal Fire AI-5 PRO Professional Optical Fiber Fusion Splicer is a six-motor core alignment fusion splicer designed for FTTH, telecommunications, security monitoring, ISP networks, and fiber optic maintenance. It delivers approximately 8-second fusion splicing and 18-second heating, with a 5-inch TFT color display, up to 320x magnification, automatic arc calibration, a 3-in-1 fiber holder, and a removable 5200 mAh lithium battery. Its built-in LED lighting and rugged portable design make it suitable for professional fiber installation and field repair work.

Product Features

Six-Motor Core Alignment

The six-motor core alignment system provides precise fiber positioning for reliable and low-loss fusion splicing.

Fast Fusion Splicing

The AI-5 PRO completes fusion splicing in approximately 8 seconds and heating in approximately 18 seconds, helping technicians work efficiently.

High-Resolution Display

The 5-inch TFT color display provides clear fiber viewing, with up to 320x magnification for accurate alignment and inspection.

Automatic Arc Calibration

Real-time arc control and calibration help maintain consistent splice quality under changing environmental conditions.

3-in-1 Fiber Holder

The universal fiber holder supports single-mode and multi-mode fiber, bare fiber, pigtails, drop cables, patch cords, and multi-core cables without frequent holder changes.

Long-Lasting Removable Battery

The 5200 mAh lithium battery provides approximately 160 continuous splice and heating cycles and can be removed for separate charging.

Built-In LED Lighting

Integrated LED lighting provides additional illumination for fiber splicing during nighttime work, emergency repairs, or low-light installations.

Fiber Data Management

The AI-5 PRO supports storage and management of splice records, helping technicians maintain installation and maintenance information.
