摘　　要：1550光插播技术的不足之处是长距离传输时数字电视MER指标迅速劣化。尝试采用光色散补偿技术来解决这一问题,经过实际调试和测试达到了设计目标,成功应用在内蒙古广电信息网络有限公司鄂尔多斯分公司各个旗县之中,取得了很好的经济效益,具有良好的推广价值。This article describes in detail that the 1550 optical insertion technique and its application deficiencies-the long distance transmission of digital TV MER specification is decreases rapidly. In this article,we have tried to solve this problem by using optical dispersion compensation technology for the first time. After the tuning and testing,the measurement results are to achieve the design goal and fit well. This technology is applied successfully among the various counties in Inner Mongolia Radio and Television Information Network Co.,Ltd. Erdos Branch. This technology is achieved very good economic benefits and has a good promotional value.
