Maximum Bus Length
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 on the bit rate.
The following table shows some examples with the bus length in
relation to the bit rate:
Bit rate
Max. bus length
10 kbit/s
6.7 km (4.2 miles)
125 kbit/s
530 m (580 yards)
250 kbit/s
270 m (300 yards)
500 kbit/s
130 m (140 yards)
1 Mbit/s
40 m (45 yards)
