This device is based on FPGA, which supports asynchronous RS232/RS485/RS422 communication interface Fiber Modem. The device is the best choice of connecting to the remote terminal unit (RTU) to a host (HOST) or a distributed data acquisition system (SCADA) controllers, with very high performance price ratio. Using ordinary multi-mode fiber, effective communication distance is up to 4KM, while using ordinary single-mode fiber, effective communication distance up to more than 40KM. Serial port communication rate is up to 921.6KBPS. As a result of the fiber as a transmission medium, you can completely avoid the threat to communication device under the adverse environment, such as lightning, surges and electromagnetic interference, at the same time it saves investments of the original lightning surge protection devices that using copper .
