Overview:
Intelligent transportation is a service system based on modern electronic information technology that faces transportation; it provides diverse services for traffic participants based on the collection, processing, release, exchange, analysis, and utilization of information. It is mainly composed of vehicle control system, traffic monitoring system, traffic management system, information service system, electronic toll collection and emergency rescue system. As more and more business systems are carried by the entire transportation network, and the requirements become more and more demanding, how to Ensuring the stable operation and flexible expansion of the entire transportation network is an urgent problem to be solved.
EPON is a passive optical network based on Ethernet. It has the advantages of simple networking, high performance, and flexible expansion, and has been selected as one of the main technologies for the construction of intelligent transportation networks.Intelligent transportation solutions based on EPON networking communication, forsmart transportationThe promotion and construction of the company pointed out the direction
System composition:
This system mainly includes three parts: optical line terminal (0LT), optical distribution network (0DN) and optical network unit (ONU). Among them, the OLT is located at the central office, the ONU is located at the user end, and the ODN is composed of passive optical splitting devices and optical fiber lines.
