For optical communication component manufacturers, fiber optic connector producers, and quality control engineers, the persistent challenge remains consistent: performing high-precision inspection of fiber end-face geometry (radius of curvature (ROC), vertex offset, concavity/convexity, fiber height, apex angle) to ensure low insertion loss and back reflection in high-speed optical networks (5G, data centers, FTTH). Single-core fiber end-face interferometers utilize interferometry technology to measure sub-micron surface profiles (nanometer accuracy) of polished fiber connectors. They are widely used in production and quality control of fiber optic connectors (ferrules: ceramic (zirconia), glass, metal), optical modules (transceivers, AOCs (active optical cables)), and high-speed communication devices. Key magnification options include 10X (large field of view, ferrule geometry, general inspection), 20X (balanced detail vs. field, standard for most QC), 40X (high magnification for micro-defects, R&D, failure analysis), and others (custom magnifications). Applications span fiber optic connectors (SC, LC, FC, ST, MPO/MTP, MT ferrule) and communication components (optical transceivers, silicon photonics chips, PLC splitters). Upstream raw materials include precision interferometric optical components (lasers (633nm He-Ne or 850nm VCSEL), beamsplitters, lenses), CCD/CMOS detectors, and high-stability mechanical platforms. Major component suppliers include Hamamatsu Photonics, Thorlabs, and Edmund Optics. Downstream customers include Corning, Sumitomo Electric, OFS, Huawei HiSilicon, Changfei Optical Fiber, and other optical component manufacturers. In 2024, global sales reached 24,000 units with an average selling price of $19,000 per unit.
