Moxa’s serial converters, serial-to-fiber converters, and fieldbus fiber converters provide efficient solutions for industrial communication. Moxa’s serial converters adapt traditional serial protocols to Ethernet networks, while serial-to-fiber converters transmit serial communication over fiber for longer distances and interference resistance. Fieldbus fiber converters, on the other hand, convert fieldbus communication to fiber, ensuring reliable and fast data transmission in industrial applications. The main differences between these devices are in the communication protocol used and the transmission medium.
