Fiber Selection & Fiber Length - ICP DAS USA I-2533CS-FD User Manual

3.2. Fiber Selection & Fiber Length
The specification of fiber cable used to connect the I-2533CS-FD is shown as
following table.
Single mode
The I-2533CS-FD allows maximum 30km fiber length for each kind of CAN baud
theoretically. Although the maximum fiber length has no relationship with the CAN baud
rate, but some fiber attributions, such as attenuation, still influence it. Higher attenuation
of fiber will reduce the transmission distance. User can use following table to know the
relationship between those two.
