Huawei's Campus OptiX, based on POL technology, is tailored for various scenarios, including airports. According to HCSA-Sales-Transmission & Access documents, the key advantages in the airport scenario include:

Smart O&M (A): Campus OptiX leverages eSight NMS for intelligent operations and maintenance, simplifying network management in large-scale environments like airports.

Up to 40km Coverage (C): POL's passive optical architecture supports long-distance coverage (up to 40km), ideal for expansive airport campuses.

Ultimate Wi-Fi Experience (B): While Campus OptiX supports high-speed connectivity, this advantage is more emphasized in scenarios like hotels or offices with Wi-Fi roaming features, not specifically highlighted for airports.

Thus, A and C are the verified advantages.
