Abstract

As an important component of information infrastructure, the technical system of optical fiber communication systems has been continuously evolving over the past two decades along with the expansion of network scale and changes in business forms. Optical signal modulation and demodulation technology directly determines the transmission efficiency, stability and engineering adaptability of optical fiber links, and is a key technical link supporting the continuous upgrading of backbone networks, metropolitan area networks and access networks. Based on the practical experience of optical fiber communication engineering construction in China, in terms of system architecture, equipment selection and operation and maintenance, more practical application requirements for modulation and demodulation technology have been put forward. This article discusses the basic composition of optical fiber communication systems and the principles of optical signal modulation and demodulation. On this basis, it focuses on analyzing several innovative application practices of modulation and demodulation technologies in China’s optical fiber communication systems.
