440nm 1x2 High Power Large Core Multimode Fiber Coupler

VIS-MFC -LMA series large core fiber couplers are developed and produced based on our fiber fusion taper machine IPCS-5000-LMA. They are used for visible light band splitting. They have excellent performance. Unlike multimode fibers (50/125, 62.5/125) widely used in fiber optic communication systems, large core fibers are usually used to transmit larger laser powers and special working bands. At the same time, due to the large core diameter and high numerical aperture of the fiber, the uniformity and stability of large core fiber splitting are affected by many factors (such as laser mode, laser injection method, etc.). With the accumulation of many years of high-energy laser transmission experimental foundation and the research on the reliability of military devices, we can provide fiber splitters with core diameters of 125um to 1500um, as well as large core fiber splitters working at all wavelengths. The products have extremely high resistance to high-power laser shock and high environmental reliability. Since its establishment, the company has continuously invested in research and development to optimize and improve the melting process of special large core fiber splitters and product packaging processes. We have made breakthroughs in product miniaturization, multi-core optical fiber one-time melting molding, laser mode sensitivity removal, etc. We have provided large-core optical fiber splitter products exclusively to many domestic and foreign customers.
