| Abstract: | The DWDM technology allows various carrier current channel to transmit in an optical fiber, fully has used the optical fiber bandwidth, may directly turn on the many kinds of services, transmits the platform based on DWDM SDH to become the backbone transmission the mainstream. In this platform, part of band widths use for to transmit the broadcast television program, another part uses for the direct transmission user data and so on. This paper introduces the fault in the transmission of television signal in the province network and solutions. |
