Abstract

With the development of the global Internet industry, the demand for the transmission capacity of communication system is increasing rapidly. Optical fiber has become the main transmission media in communication systems because of its unique advantages, such as large bandwidth and low loss. It is necessary to construct large capacity optical communication systems to satisfy the capacity requirements. In this paper, the overall architecture for optical short-reach pulse amplitude modulation (PAM) transmission system is analysed. Then the signal damage factors and corresponding compensation schemes based on digital signal processing (DSP) are studied. The different implementation schemes for clock recovery and channel equalization are described and compared in detail. Finally, the challenges and prospects of DSP technology in short-reach PAM transmission system are discussed.
