Analysis On The Design Of The Optical Fiber Communication Signal Acquisition Experiment Teaching System

A typical experiment signaling acquisition system structure generally use distributed processing, the system includes three parts WAN, remote stations and the central station.WAN responsible for the system original data transmission and generate CDR (Call Detail Record);Remote station set up in a signaling relatively centralized location;Central station centralized LAN maintenance and management with graphics workstations and the central server coordinating. Systems collect data directly through a high impedance adapter, and then after long runs routed to the remote station;After the completion of the relevant remote data acquisition and pre-processing, data reports generated by WAN to the central station server, stored in the database.In the specific experimental teaching, if optical fiber communication experiment just only simply used wire to connecting in the experimental box, the teaching experiments effect will be seriously affected.In this paper, the design of optical fiber communication signaling acquisition experimental teaching system aimed to the experimenter autonomous learning. Experimenters should have a certain degree of learning basic and learning skills, also include certain requirements on learning motivation-. learning consciousness、learning planning、learning directionality and other aspects.Designing and analyzing based on optical fiber communication signaling collecting teaching system, this work briefly introduces optical fiber communication experiment teaching status, purpose and design ideas, and explain and illustrate the relevant basic theory of the system. It details the system design, including system architecture, functional systems and experimental content. By using Multisim 11.0 circuit simulation software for system simulation, this work made out a simple physical model and test the data related hardware circuit. The design implement low signal distortion, high SNR, meet the signal transmission quality requirements, provide theoretical and design reference for the realization of a low-cost high-quality transport solutions and effective platform for experimental teaching.
