Design Of The Point-to-Point Communication System Based On The Plastic Optical Fiber(POF) Technology

Optical fiber is compared to the arteries of information transmission in"information society"by the scientific community. The major developed countries all have placed the development of optical fiber communications as a key of national policies. Among optical fiber, plastic optical fiber's diameter is usually between 0.3-3mm. With the large diameter, the connection is easier and the efficiency of optical coupling is higher. So large-core plastic optical fiber can be manufactured. At the same time, the plastic optical fiber (POF) has excellent softness, bending resistance, shock resistance and radiation resistance. The price was cheap. Its connection and construction is convenient. POF can be a substitute for the traditional quartz fiber and copper cables. All of these advantages help to sharply lower the cost of optical fiber communication system. So POF is very suited to be applied in the LAN with more nodes, for example, the communication system of medical equipment, industrial control systems, optical fiber sensors, automotive network, military affairs, airplane and aircraft carrier.The research and development of POF materials and network equipment will provide better solutions to the connection of the higher rate network. Currently, many companies and the Association for Standardization have joined the rank, devoting a lot of manpower and material resources. As an alternative to copper wire and optical fiber products, its application has been supported by various technical standards, such as Ethernet, 1394, ATM all have developed related POF technical standards. It can be predicted that with the unique technical features, POF technology will have even broader prospects in the integrated wiring, LAN and multimedia applications, and will become the main transmission medium of next generation broadband access network. Therefore, the research of related problems about the communication system based on POF technology is significant. The experimental system is proposed for this purpose.Based on substantive literature, the author went along deep studies about POF communications system through the computer simulation and actual circuit testing. The main results are as follows.
