[Abstract]:With the development of modern information technology, the demand of information flow and system bandwidth in the field of communication is increasing. Optical fiber communication based on optical wave has become an important modern communication mode. Faster and faster high-speed signals, optical fiber communication transmission bandwidth, communication capacity, strong anti-electromagnetic interference ability. The advantage of confidentiality is very suitable for applications with high transmission rate and transmission distance. Nowadays, there are many serial buses that can provide transmission rates ranging from 2.5Gbps to 10Gbps. The high speed interface of communication is a kind of product which combines optical fiber communication with high speed signal transmission. The high speed interface used in optical fiber communication is transmitted by high speed differential signal, because differential signal can avoid the interference of common-mode noise. . Reducing EMI radiation can also overcome many disadvantages of single-ended signals, such as crosstalk from other signals or external environments, and jitter on the power / ground plane. These characteristics are very suitable for the transmission of signals with a rate of up to Gbps. This paper aims at the above problems. Taking the high-speed interface of 2.5Gbps signal used in optical fiber communication as the main research object, it is divided into two parts, modeling and performance optimization, in the process of modeling the detailed high-speed interface. The factors that affect the characteristics of high-speed interface and the modeling method of each component of high-speed interface are discussed. Through the process of simulation verification, how to optimize the performance of high-speed interface is studied. The main contents of this paper include the following parts: 1. Introduce the development of high-speed design and optical fiber communication, the introduction of high-speed interface. The main work and structure arrangement of the paper are summarized. 2. Starting with the design foundation of high-speed interface, the related electromagnetic field knowledge is introduced. Then some factors that may affect the performance of high-speed interface are introduced. Finally, the background knowledge of high-speed interface modeling is introduced. 3. The block diagram structure of high-speed interface is determined. The components of high speed interface are introduced. The process of modeling and simulation optimization of high speed interface is described. The modeling of high speed interface is carried out. The key parameters of each component of high speed interface are extracted. The 3-D model of each component of high speed interface is solved by using a solver based on finite element method or integral equation provided by 3-D full-wave electromagnetic field simulation software. Extract the key parameters of performance evaluation to complete the high-speed interface model .5. simulate the established high-speed interface model and optimize the high-speed interface performance according to the simulation parameters. This paper introduces the reasons and concrete methods of optimization, summarizes the shortcomings and limitations in the modeling and research process of high-speed interface, and plans the next work arrangement.
