Need to extend the range of an RS232 serial connection or protect it from electrical noise? This media converter is your answer. It takes a standard DB-9 RS232 signal (RX, TX, GND) and converts it to a fiber optic signal over single-mode fiber with an SC connector (1310nm wavelength, up to 20 km range). It also works the other way around (fiber to RS232). This lets you run data over long distances without signal loss and makes it immune to EMI/RFI interference. It supports daisy-chaining or setting up redundant ring networks (up to 32 nodes). Has built-in surge and static protection. Powered by a 5V/1A UL-certified adapter. A must-have for industrial automation, security systems, or any application where you need robust, long-distance serial communication.
