In this paper, we estimate the availability of a general purpose LAN (Local Area Network)
as an on-board network from the aspects of the transmission medium characteristics and the
transmission delay.
Optical coupler which connects eight optical fibers between two cars, and the transmission
system which transmits equipment controlling signals have been tentativery made and tested.
The anti-electromagnetic noise characteristics of the co-axial cable and the twisted pair
cable have been measured and the transmission delay time has been measured and simulated.
From the results of these experiments, we get good prospects of constructing the on-board
network by using the general purpose LAN.
