DY-5977S multi-channel serial to Fiber multiplexer can realize multi-
channel RS-232/RS-485/RS-422 transmission on one optical fiber, which not only
saves fiber resources, but also uses optical fiber as transmission medium, which has
isolated high voltage and anti-electromagnetic Interference, anti-lightning and other
advantages. It is widely used in various industrial control and industrial
automation fields, and is particularly suitable for power system automation,
traffic control and other machinery.
