DM-41S Fiber Optic Splicer – Product Overview

High-Efficiency Fiber Splicing
The DmInteract DM-41S delivers rapid fiber optic splicing with an 8-second welding cycle and 18-second heating cycle. This high-speed performance enables technicians to complete more connections in less time, boosting operational efficiency.
Advanced Motor System
Equipped with a 6-motor drive system and precision micro-step guides, the DM-41S reduces positioning errors and fiber loss compared to traditional 4-motor systems. This design ensures faster splicing and higher overall work efficiency.

Integrated Optical Tools
The DM-41S features a built-in red light source (VFL) and optical power meter (OPM) supporting six wavelengths with self-calibration. It offers large-capacity data storage, saving tens of thousands of measurement records for easier project tracking.

Power and Battery
Powered by a 7800 mAh lithium battery, the DM-41S can perform approximately 240 welding and heating cycles per charge. The battery also supports USB charging for mobile devices and exporting splicing data.

User Interface & Display
Featuring a 5-inch SPI HD touchscreen with an intuitive graphical interface, the DM-41S displays X/Y axis alignment, welding loss, and cutting angles. Intelligent detection and alerts minimize errors and improve workflow efficiency.

Applications
The DM-41S is ideal for FTTH installations, communication engineering, security monitoring, metropolitan area networks, fiber optic renovations, and power optical cable splicing. The compact design (191 × 141 × 119 mm) ensures portability and convenience on-site.
Key Features
- Core alignment technology for precise splicing
- Active Fusion Control Technology to minimize splice loss
- Automatic Active Blade Management for cleaver blade rotation
- 5-inch touchscreen with intuitive graphical interface
- Automated wind protector and sheath clamps for smooth operation
- Lithium-ion battery supporting 240 splices per charge
