    Usage Instructions：

    1. Appropriate ESD protection measures should be implemented to prevent electrostatic discharge (ESD) damage.

    2. Do not pull or apply excessive force to the tail fiber directly, as this may damage the optical component.

    3. Keep the optical connectors clean and free from dust or contaminants to ensure optimal optical performance.
