Tips: What is Fiber Converter?
RS232/ 485/ 422 optical fiber converter realizes one RS232 or RS485 or RS422 through single-mode optical fiber for long-distance transmission. This product has the characteristics of RS485/ 422 interface supporting multi-machine communication and convenient networking . At the same time, due to the use of optical fiber as the transmission medium, it has the advantages of high isolation voltage, anti-electromagnetic interference, and anti-lightning strike.
232/ 485 optical fiber converter is widely used in various industrial control, distributed data acquisition and other occasions, especially suitable for power system automation, traffic control and other departments.
