Typical fiber connectors (such as FC/PC, SC/PC, MPO) require direct contact between the fiber end faces. When contaminant particles (with a diameter > 5 μm) are present on the end faces: a micron-level gap is formed (even a 0.1 μm gap will cause a 0.3 dB loss), resulting in Fresnel reflection (each contaminant point reflects approximately 4% of the optical power). If a situation like the one shown in the picture occurs, typical fiber connectors would have already failed, but AR fiber connectors, through a special process of coating and grinding the concave surface, the degraded connectors still have a test insertion loss below 0.5 dB.

    The AR Fiber Optic Connector replaces the direct contact, standardized optical design and anti-pollution/maintenance mechanisms of ordinary connectors with coating and grinding indentation processes. This significantly enhances the tolerance for errors during connection and environmental interference, thereby achieving excellent random compatibility and becoming a highly reliable and easy-to-maintain optical connection solution.

    Due to the unique manufacturing process of the AR Fiber Optic Connector, it effectively prevents mechanical wear and end-face damage that may occur during the insertion and removal of the connector, thereby extending its service life.

    The customer has found that the AR-MPO plug-in testing method provides excellent protection for the end faces.

    The use of AR Fiber Optic Connector ensures that there is always a very small distance between the tested product and the connector end face. During insertion and removal, there is absolutely no physical contact, fundamentally avoiding scratches, cracks or material wear caused by end face friction in traditional contact-type connectors.
