Maximum Bus Length
High-speed CAN networks may have bit rates of up to 1 Mbit/s,
where all CAN nodes must be able to process messages
simultaneously. 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
