In this paper, in order to improve the reliability of Ethernet communication, the effect of pulse disturbances on the communication quality of 100BASE-TX was evaluated experimentally. A relationship between the threshold level of Ethernet and disturbances affecting communication quality was revealed when the amplitude and width of the pulse disturbance were changed. A disturbance in which the pulse width was the same as 1 bit time of the signal degraded the communication quality the most. These findings should help in the effort to apply Ethernet to automotive area network.
