I-2533CS-60 – CAN to Single Mode Fiber Bridge
New Products
2015-08-25
The I-2533CS-60 is a local CAN bridge used to establish a connection between two CAN bus systems via single mode fiber transmission medium. In order to solve the problem between CAN and fiber transmission mediums, the I-2533CS-60 is specially designed to convert the electrical CAN bus signal to optical signal, and the signal can be recovered to CAN bus by using another I-2533CS-60. Comparing with other CAN/Fiber converters, the I-2533CS-60 has three more important features. First, the transmission distance limitation of the CAN bus system will not be reduced due to higher CAN baud rate. No matter what kind of CAN baud rates you use, the data transmission distance of fiber can reach up to 60 km. It means that the total network working distance can be extended.
Second, the error on the CAN bus side of the I-2533CS-60 will not affect the general operation of the side on the fiber optic cable.
Finally, you can use different baud rate in the CAN networks at both ends of the fiber optical cable if necessary.
The main difference between I-2533 and I-2533CS-60 are the different type of fiber connectors and transmission distance. The I-2533CS-60 is designed for single mode fiber, and allow to extend CAN bus to maximum 60 km. Besides, the I-2533CS-60 provides group function which functions as basic message router. Users can decide the CAN message flows between several CAN bus systems.
The I-2533CS-60 provides an utility tool for user-defined baud rate and message filter configuration. When users use the I-2533CS-60 on two CAN networks which have different CAN baud rate, it may be useful to reduce the bus loading on the network.

The I-2533CS-A and I-2533CS-B are a couple and must be used in pairs in CAN Bus applications.
*note2:
The propagation delay depends on the CAN Bus baud rate and the CAN message format. This value has been tested using a CAN baud rate of 1 Mbps, the CAN ID 0x1234567 and 8 bytes of data with a value of 0xFF.
