Ethernet LAN and industrial networks is the mainstream networks , because of its agreement with the CSMA / CD protocol , real-time and sometimes can not be guaranteed , there is difficult to realize the shortcomings of the variety of data transmission . To fundamentally overcome this disadvantage of the Ethernet , while a good convergence and the Next Generation Network (NGN) , the design of a new network , it can make the different operations , different data structures , the different transmission rates , different signaling connection can be transmitted in the same network , which is the the broadband integrated data synchronous optical network ( WIDOSNet ) . The method is to solve the above-described many problems , demand assignment channel capacity , to achieve the separation of transmission and business , transmission, and control the separation . Broadband integrated data network synchronous optical network structure is mainly composed of two parts of the concentrator node . Node system design in the past , its backplane data transmission is a parallel transmission . Continue to enhance the transmission rate of the network needs over 1Gbps data rate , many problems do not have to be considered at low frequencies the fore , such as reflections, crosstalk , simultaneous switching noise and other signal integrity issues , parallel transmission is no longer reliable and economic method . How resolve bottlenecks met in the hardware system , this is the article discusses design : the parallel transmission of high-speed serial transmission instead of the original design of the program . Broadband data synchronous optical network this high-speed digital circuit signal integrity problems that occur in the process of designing and implementing a simulation analysis , the solutions of the two main reflections and crosstalk signal integrity issues and give suppression strategy . Improved design and serial - based transmission network node structure of the the broadband integrated data synchronous optical network , in order to better meet the high speed and reliability of the system transmission , an FPGA-based solution designed hardware circuit .
