400/440um multi-mode fiber connector

Large-core fiber optic connectors offer excellent performance. Unlike the multimode fibers (50/125, 62.5/125) widely used in fiber optic communication systems, large-core fibers are typically used for transmitting higher laser power and operating in specific wavelength bands. Furthermore, due to their large core diameter and high numerical aperture, the uniformity and stability of light splitting in large-core fibers are subject to interference from various factors (such as laser mode and laser injection method). Building on years of foundational experience in high-energy laser transmission experiments and research into the reliability of military-grade components, we can now provide fiber optic connector products with core diameters ranging from 125um to 1500um, as well as large-core fiber products operating across the full wavelength spectrum. These products possess extremely high resistance to high-power laser damage and offer excellent environmental reliability.
