Product Description

Fiber modem can be connected with computer or other devices via Lotus screw type terminal. This is a small and flexible device which can solve the problem of traditional RS232 communication conflict between distance and rate. Electromagnetic interfere, lightning interfere ,improve the reliability ,safety, and security of data communication, suitable for industrial control, procedure control, and traffic control, especially for system in bank, electric, and environment which having special requirement for electromagnetic interfere.
