Essential Tools for Laser Source Repair: A Professional Overview

November 24 , 2025

In the rapidly evolving field of fiber optic technology, maintaining and repairing laser sources is crucial for ensuring reliable performance in telecommunications, sensing, medical devices, and industrial applications. At SeikoFire, our Laser Source Repair Tools series offers a comprehensive suite of precision instruments designed to handle large-diameter and specialty optical fibers. These tools, including recoaters, cleavers, strippers, OTDRs, and fusion splicers, are engineered for efficiency, accuracy, and durability, backed by our 25 years of expertise in optical communication solutions.

Our lineup starts with the Optical Fiber Recoater SH-T101, which restores the protective coating on spliced or bare fibers. Using high-refractive glue that cures injust 1 second, it protects splicing points and enhances fiber elasticity, making it ideal for single-mode, multi-mode, and polarization-maintaining fibers. For precise cutting, the SH-D104 and SH-D103 Large Diameter Optical Fiber Cleavers stand out. These devices handle fibers from 40-600μm, with adjustable tension and blade mechanisms for clean, high-efficiency cuts in production lines or R&D settings. They are perfect for photon crystals, doped fibers, and glass capillaries.


Complementing these are tools like the Special Fiber Optical Heat Stripper SH-R401, which provides automatic, longitudinal stripping without damaging the fiber core, thanks to its precision motor drive and replaceable blades. For testing, the Large Diameter Fiber OTDR SH-DXJ200 offers compact, reliable measurements of fiber characteristics, including attenuation and irregularities, with easy data archiving and printing. Fusion needs are met by models such as the S500M Large Diameter Fiber Fusion Splicer, featuring six-motor core alignment, real-time ARC calibration, and a user-friendly 5-inch touch screen. The Laser Source S400 LDF Fusion Splicer excels in splicing 125-500μm fibers with low loss (as low as 0.01dB for multi-mode) and quick splice times of 8-10 seconds, ensuring high return loss (>60dB) and robust tension testing.


These tools are not just about repair—they enable proactive maintenance, reducing downtime and extending the lifespan of laser sources in demanding environments like gyroscopes, lasers, and communication networks. By integrating advanced features like environmental compensation and multi-language interfaces, SeikoFire's repair tools empower technicians to achieve professional-grade results with minimal effort.
