2 Channel CAN Bus to Fiber Converter

View : 474
Type : CAN Bus to Fiber Converter
Description :

The CAN Bus to fiber converter can transfer the CAN bus signal to the optical signal and transmit it over fiber, which can extend the communication distance of CAN bus.


The CAN fiber modem can transfer the CAN bus signal to optical signal and transmit over fiber, which can extend the communication distance of the CAN bus. At the same time, due to adopting optical fiber communication, solves the problems of electromagnetic interference, ground ring interference, and lightning damage, greatly improves the reliability, security, and confidentiality of data communications and can be widely used in various industrial control, process control and traffic control applications. It is particularly suitable for banks, power, and departments or systems that have special requirements for electromagnetic interference.
