2 Port CAN Bus to Fiber Converter

The CAN Bus to fiber converter can convert the CAN bus signal into an optical signal for transmission over optical fiber, effectively extending the communication distance of the CAN bus. By utilizing optical communication, it solves the problems of electromagnetic interference, ground loop interference, and lightning damage, significantly improving the reliability, security, and confidentiality of data communication. It can be widely used in various industrial control, process control, and traffic control applications, especially suitable for banks, power companies, and departments/systems with special requirements for electromagnetic interference environments.

● The device provides 2 CAN bus interfaces and 1 optical port.

● The CAN data communication is fully transparent, and the baud rate is self-adaptive without any configuration required.

● The CAN interface can support up to 128 nodes, and the maximum speed is 0-1Mbps, complying with international CAN 1.0 and CAN 2.0 standards.

● It is powered by a wide range of DC 9-55V or AC 7-50V power supplies, with an automatic polarity detection function that eliminates the need to distinguish between positive and negative poles during installation.

● DIN 35mm rail mounting or wall mounting.

● The CAN interface is equipped with lightning protection, which meets the GB/T17626.5 (IEC61000-4-5) standard, with a short-circuit current wave of 8/20μs and an open-circuit peak output voltage of 6KV.
