Optical data transmission modules utilize the high directionality of lasers to achieve high-speed data transmission between two designated targets. Compared to traditional electromagnetic wave communication technology, laser communication offers lower transmission latency, greater bandwidth, and virtually no interference between channels. In scenarios where cable installation is not feasible or where high data transmission real-time performance is required, optical data transmission modules are an ideal solution. The DADISICK ST100 optical data transmission module supports spatial laser communication with any protocol within 200 meters, providing a transmission bandwidth of up to 100 Mbps. Additionally, the ST100 is equipped with various interactive features (such as status indicators and configuration interfaces) and user-friendly installation designs, significantly improving installation and debugging efficiency. It is widely applicable in industrial automation, drone communication, and temporary network deployment.
