Quick Start User Guide
1. Introduction
Fiber optic transmission medium is a good material to protect data
transmission from EMI/RFI interference and has been used in harsh
environment extensively. CAN bus is famous in industrial application.
More and more users build CAN networks to communicate their
controllers, sensors and actuators. In order to solve the problem between
different transmission medium, I-2532 is specially designed for converting
the electrical 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. Generally, I-2532 can be used in CANopen, DeviceNet and all
the other CAN network which follows the ISO 11898-2 standard.
This quick-start describes how to implement the I-2532 module into
users’ applications in a quick and easy way. Therefore, it only provides the
basic concepts. If users want to know more detail information about the I-
2532, please refer to the user manual of I-2532 in the product CD or visit

4. LED Indicators & Terminal Resistance
The table below shows the meanings of LED indicators on the I-2532.
Transmitting/receiving one message to/from fiber cable will flash the
TD/RD LED once. The TD/RD LED may always be turned on if there are
a lot of messages transmitted on fiber cable.

6. Bus Length & Fiber Length
Higher attenuation of fiber will reduce the transmission distance. Users
can use following table to know the relationship between those two.
Attenuation [dB/km] Ideal Fiber Length [m]
2.8 <1400
4 <400
The limitation of baud on a CAN network is restricted by propagation
delay. On the other hand, long bus length leads to long propagation delay.
The relationship between baud and bus length is displayed below.
Baud [bit/sec] Ideal Bus Length [m]
500K < 100
250K < 250
125K < 500
50K < 1000
20K < 2500
10K < 5000
The definition of segments the relationship between segment length
(L
SEG1
, L
SEG2
…) and bus length (L
BUS
) in the same CAN bus system are
shown in the following figure.
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 the CAN
network, the ideal bus length should less than 950 meters (1000-
25*2=950).
