The KY-MWF208 Multi-channel data multiplexing optical transceiver can provide multi-channel RS-232 / RS-485 / RS-422 transmissions over one optical fiber link. This not only saves fiber resources, but also uses optical fiber as transmission medium to opto-isolate high voltages and prevent electromagnetic interference. ,and anti-lightning. Widely used in various industrial controls and electrical switchgear. Also widely used in the field of industrial automation, especially suitable for power system automation, traffic control and factory automation, including power wind farms.
