    CAN bus signal to fiber optic cables. The fiber length between two I-2532s can be up to 1.4km (4593ft), it is mainly decided by the cable attenuation of fiber and the CAN bus baud. I-2532 is the economic solution for applications which require protecting the data transmission from electrical exposure, surges, lightning or chemical corrosion.

  • Page 13: Baud And Bus Length

    I-2532 Figure 3-2 Segment Length and Bus Length When users add one pair of I-2532 into a CAN bus system, the ideal bus length will reduce 50 meters because the propagation delay of one I-2532 is equal to the propagation delay caused by 25 meters bus length. For example, if users use baud 50Kbps and add two I-2532s into a CAN bus system, the ideal bus length should less than 950 meters (1000-25*2=950).
