3.4.3 Maximum Bus Length
High-Speed-CAN networks may have bit rates of up to 1 Mbit/s. The
maximum bus length depends primarily on the bit rate.
The following table shows the maximum possible CAN bus length
at different bit rates:
Bit rate Bus length
1 Mbit/s 40 m
500 kbit/s 110 m
250 kbit/s 240 m
125 kbit/s 500 m
50 kbit/s 1.3 km
20 kbit/s 3.3 km
10 kbit/s 6.6 km
5 kbit/s 13.0 km
The listed values have been calculated on the basis of an idealized
system and can differ from reality.
