【摘要】 为了解决视频信号在远距离传输中的损失问题,研制了一种新型光纤收发器。收发器的传输速率可达1.25Gb/s,传输距离超过20Km,在远程视频传输试验中,视频信号在传输超过20Km后可成功复现,动态效果良好。系统已通过验收,各项指标均满足要求。更多还原

【Abstract】 A new optical receiving-transmitting modules is manufactured to solve the loss of video signal in the long-distance transmission. The rate of transmission of the optical receiving-transmitting modules can reach 1.25Gb/s, and the transmission dis-tance of the modules exceed 20Km.In the test of long-distance video transmission the video signal can be recurred in the trans-mission over 20Km,and the dynamic effect of the signal is well. The system has been passed the check and acceptance, and ev-ery guide line can meet the desire of system.更多还原
