M1 Fusion Splicer
A fiber optic fusion splicer is to join two optical fibers. It generates an electric arc to melt the fiber ends, creating a low-loss, high-strength permanent connection that ensures efficient signal transmission.
Highlights

- High precision & ultra-low loss fusion splicing. The average loss is as low as 0.02 dB for single-mode and 0.01 dB for multi-mode fibers. This results in stronger signal integrity, reduced network downtime, and superior performance in long-haul and high-speed fiber networks.
- 7-second fast fusion and 18s heating significantly reduce project timelines.
- All-in-One Triple-Function Fiber Clamp. Our three-in-one fixture supports 0.25 mm, 3.0 mm, and flat indoor cables, making it compatible with pigtails, drop cables, and patch cords.
- 5200 mAh high-capacity lithium battery supports 240 splicing and heating operation. Compact body facilitates portability, meeting fieldwork demands.
- The smart fusion splicer features a 4.3-inch touchscreen, dual-camera real-time monitoring, 41 preset programs, and storage for 2000 splice records.
- Backed by a 3-year warranty with online support and loaner unit service, ensuring peace of mind and uninterrupted operations.
- M1 fusion splicer comes with a complete set of standard accessories, allowing you to start using it right out of the box.
