Converters of RS485 fiber cables send and receive an RS485 signal through a transformed optical fiber cable. RS485 and RS232 devices can communicate with each other without fretting about breaking the connections. The need for less electrical disturbance and long distance communication makes fiber converters essential. This is because fiber cables are less known to data transmission disturbances as compared to standard copper cables. The result is enhanced performance for long distance access. For instance, sensors and remote controllers in a vast industrial complex can be connected through RS485 Fiber Converters with a central control room for effortless long distance communication without any noise interference.
