The ICF-1171I Series CAN-to-fiber converters are used in pairs to connect two CAN 2.0 or two CAN FD devices or networks via single-mode or multi-mode optical fiber. The ICF-1171I provides 2-kV isolation protection for the CAN interface and dual power inputs to ensure that your CANbus system will work uninterrupted.
The total transmission distance of a CAN 2.0 or CAN FD system can be extended by 2 km (multi-mode fiber) or by 40 km (single-mode fiber) using ICF-1171I converters, regardless of the CAN baudrate.
Two CAN 2.0 networks or CAN FD networks can communicate with each other using different baudrates. The ICF-1171I converters can automatically detect the baudrate of the connected CAN 2.0 device and apply the baudrate to itself. Therefore, users do not need to know the baudrate of the connected CAN 2.0 device. This is an extremely convenient feature. Baudrates can also be set to a predefined value via rotary switches.
It is easy to check if an issue exists on the CAN bus or the Fiber link. The ICF-1171I converters are provided with LEDs that indicate the fiber link state, fiber communication status, CAN bus state, and CAN bus communication status.
