Abstract: With the rapid development of information technology, 10 Gigabit Ethernet plays an important role in the transmission of big data networks. However, its ultra-high speed necessitates signal integrity considerations in the improving design. Aiming at the problem of improving design of high-speed link of 10 Gigabit Ethernet card, the transmission characteristics of high-speed serial link before and after the improvement are analyzed, the simulation model of the link is established, and the simulation model is verified by actual measurement of eye diagrams.For the simulation results of the improved scheme, it is analyzed and optimized in terms of signal integrity, and finally put on board for testing.The testingresults show that the signal quality of the improved 10 Gigabit Ethernet card is comparable to that before the improvement. The improvement scheme is successful on the first attempt and runs stably, providing users with an efficient and convenient experience.
