Overview
     MOD-RS RS232/485/422Fiber Modem Converts the electrical signal into optical signal for transmission over fiber optic cable. It not only resolves the contradiction between communication distance and communication data rate, but also resolves the difficulties of electromagnetism molestation, geographical surroundings molestation and so on, which greatly improves the reliability and security of the data communication.
