Abstract
With the rapid development of digital media and HD broadcasting technology, the traditional broadcasting transmission system is faced with multiple problems such as insufficient transmission bandwidth, declining signal quality and secure transmission challenges. The popularity of high-definition video content puts forward higher requirements for the transmission bandwidth, while the traditional radio wave or copper wire transmission mode is difficult to meet the current demand in terms of bandwidth, transmission distance and signal quality. As an efficient and large-capacity communication mode, optical fiber communication has the advantages of rich bandwidth resources, long transmission distance and stable signal quality, and has become a key technology to solve the bottleneck of broadcast transmission. This paper studies the application of optical fiber communication in broadcast transmission system, analyzes the technical bottleneck of the current broadcasting transmission system, and discusses the basic principles and its advantages in broadcast transmission. According to the challenges of balance between transmission bandwidth and signal quality, signal attenuation and distortion, the strategy of optimizing bandwidth management and improving signal quality and secure signal encryption and broadcast. By introducing optical amplifier, distributed Raman amplification technology, dispersion compensation module, DWDM multiplexing technology and intelligent signal interference recognition algorithm, this paper provides a comprehensive solution for the application of optical fiber communication in the broadcast transmission system, and looks into the future development trend.
