Following the development of the high way, the communication system of rescue for the high way is becoming more and more important. A new PON technology for the emergent telephone system of the high way is proposed. A concrete solution for this kind of network is also illustrated. Besides, system cover-range is calculated theoretically. Our project makes full use of the advantage of PON technology, and deduces the cost of installation and system maintenance for the first time. The application of this project demonstrates that it can offer a more efficient, safer and reliable solution for high way rescue.
