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

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
