摘　　要：通过自行研制的聚合物光纤波长转换器和集线器,实现了石英光纤传输介质到聚合物光纤传输介质的工作波长转换,以及多路聚合物光纤传输信息的交换和局域网信息的全聚合物光纤传输.系统测试结果显示,数据交换传输速率达到100Mbps,通信眼图清晰.链路系统传输信号随传输距离成指数衰减,与聚合物光纤的光强衰减规律一致.用商用的发射接收器测得传输距离达到60m以上.聚合物光纤弯曲半径为25mm时,给系统接收端接收信号强度带来0.1~0.4dB的衰减,表明聚合物光纤弯曲对链路系统工作影响较小.Polymer optical fiber (POF) wavelength converter and hub are reported. With the help of these two devices, the corresponding wavelength is converted by wavelength converter from silicon to polymer fiber; the signal from different channels is switched by POF hub and transmitted only by POF in the LAN. The test results indicate that the transmission speed is up to 100Mbps. Clear Eyes diagram is obtained. The attenuation of signal in the link system is consistent with exponential function of optical power attenuation along the fiber. The transmission distance measured with commercial transceiver is up to 60m. When we bend the POF with radius of 25mm, 0.1~ 0.4dB attenuation will be induced to the signal intensity of the system receiving termination. This shows that the bending of polymer optic fiber has less influence on the communication of link system.
