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。
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 distance of the modules exceed 20Km.In the test of long-distance video transmission the video signal can be recurred in the transmission over 20Km,and the dynamic effect of the signal is well. The system has been passed the check and acceptance, and every guide line can meet the desire of system.
