The AR Fiber Optic Connector achieves optical signal transmission through a specially designed optical structure: fiber concave grinding and end face coating, thereby avoiding direct physical contact between the fiber ends.

Grinding Depression

End face coated with AR film

    The AR Fiber Optic Connector is a high-performance optical fiber connection device. Its core design concept is to reduce wear, contamination and signal loss by avoiding direct physical contact between the fiber end faces. It employs two key technological processes: grinding depressionand end face coated with AR film.

    Grinding Depression: This refers to the process of grinding the fiber end face into a specific concave shape (such as spherical or inclined), creating a tiny gap (usually a few micrometers) between the two ends during connection. This gap enables efficient coupling of optical signals through reflection and transmission, while avoiding scratches and contamination caused by direct contact.

    End face coated with AR film: This refers to applying an optical film to the end of the optical fiber. This film can optimize the transmission of optical signals, reducing reflection and scattering losses.

    Common optical fiber connectors

    Due to the limited mechanical alignment accuracy and interface Fresnel reflection (R ≈ 4%), residual optical fields form Fabry-Perot cavity effects between the ends, causing insertion loss fluctuations and echo interference. The root cause lies in the nanoscale air gap defects and waveguide mode mismatch.

    AR Fiber Optic Connector

    Unlike ordinary optical fiber connectors, when the AR Fiber Optic Connector is connected, the fiber end faces do not directly touch. The MT core passes through the AR coating on the end face to eliminate reflections at both interfaces, thereby eliminating the resonant cavity and greatly reducing the interference from resonance and reflection. There is a certain air gap between the end faces, which can protect the fiber end faces of the connector from damage.
