With a pair of CLR-STF-xx serial to fiber optical modems, any two pieces of serial equipment wich have RS422/RS485 interface can communicate at half or full duplex speeds over two fiber cores at serial communication rates up to 500KBPS. Fiber lines are insensitive to EMI/RFI and transient surges, so they are ideal for data communications near heavy electrical equipment and other electrical or radio interference.
CLR-STF-xx is based on FPGA, which supports asynchronous RS422/RS485 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.
