This product has a wide range of industrial applications: In emergency relief scenarios, such as complex and volatile battlefields, where communication is disrupted due to irreversible natural factors, the fiber-optic communication module can be deployed to quickly establish communication lines. With the aid of heavy-lift drones, a 50km fiber-optic communication line can be laid within half an hour. This line can support 30 video channels or 200 audio channels, effectively alleviating communication issues in disaster-stricken areas.
