Design And Implementation Of High-speed Optical Fiber Communication Link Based On Shark Bus Network

With the development of modern electronic communication,aerospace,and measurement and control technology,the requirements for data communication links are becoming higher and higher.Optical fibers rely on the advantages of longer relay distance,large capacity,wide frequency band,and good anti-interference.The optical fiber communication system using optical fiber as the data transmission medium was born,and the optical fiber communication link in the system became the key;only with the high-speed and high-reliability data transmission capability can the current research trend in the field of communication be met.This paper expands the design and implementation of the high-speed optical fiber communication link based on the Shark bus to meet the data transmission needs of the Shark bus,which has important practical significance.This paper Based on FPGA and optoelectronic conversion module design,implements the high-speed optical fiber communication link of the Shark bus router.This article first analyzes the task design indicators and determines the overall design solution of the high-speed optical fiber communication link,and then details the high-speed optical fiber communication link.The key technologies that need to be involved in the optical fiber communication link have determined the main control chip with FPGA as the core,supported by high-speed serial technology,with the photoelectric signal conversion module as the interface for optical fiber communication,and Gigabit Ethernet as the sand The interface between the bus network and the host computer is supported by the reliability theory of optical fiber communication,and then the implementation of the design is modularly elaborated in terms of hardware design and software design.Finally,the link is grouped after the design is completed.Network to conduct reliability tests on the bus network.At the end of this paper,the basic function test,the overall link test,and the link reliability test were carried out on the high-speed optical fiber communication link based on the Shark bus network,and the test results were analyzed.The results show that the transmission bandwidth of the high-speed optical fiber communication link can It can achieve normal data transmission at 10 Gbps.The optical module has high reliability and wide application range.The bus network is real-time,safe and reliable,meeting the requirements of the index.
