DY-5877M fiber multi-mode fiber converter: The main function of the DYMEC Serial Link is the photoelectric conversion of RS-232/RS-485/RS-422 signals. This series of products realizes long-distance transmission of RS-232 or RS-485 or RS-422 through optical fiber. Fiber optic converters use optical fiber as the transmission medium, it has the advantages of isolation high voltage, anti-electromagnetic interference, anti-lightning and so on. They are widely used in various industrial control, distributed data acquisition and other occasions, especially in power system automation, traffic control and other departments.
