Industrial Grade 1-2 channel CAN Bus Fiber Modem

Type:FCM-C1/2 Message

Description:1 fiber interface; 1~2 CAN bus interfaces;Simultaneous transmission of 1-2 CAN bus data over fiber.

Product Description
        The CAN fiber modem can transfer CAN bus signal to optical signal and transmit over fiber which can extend the communication distance of CAN bus. At the same time due to adopting optical fiber communication it solves the problems of electromagnetic interference ground ring interference and lightning damage and 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.
