The I-2533T-FD is a local CAN/CAN FD (CAN with Flexible Data-Rate) bridge used to establish a connection between two CAN bus systems via multi-mode fiber optic transmission medium. In order to solve the problem between CAN/CAN FD and fiber transmission medium, the I-2533T-FD is specially designed for converting the electrical CAN/CAN FD bus signal to fiber optic cables. Besides, I-2533T-FD has three more important features. First, the transmission distance limitation of the CAN bus system will not be affected even the baud rates of the CAN/CAN FD are different. It means that the total CAN/CAN FD bus working distance can be extended. Second, if there is an bus error occurs on one CAN/CAN FD network, it will not affect the operation of another CAN/CAN FD network. Finally, the two CAN/CAN FD network with different baud rate can communicate with each other  which allows high flexibility.
