How far is the effective communication distance of multimode optical fiber?

The pocket RS485 optical modem adopts large-scale FPGA design and supports the fiber optic MODEM of asynchronous RS-485 communication interface. This device is the best choice for connecting the remote terminal unit (RTU) to the host (HOST) or distributed data acquisition system ( SCADA ) controller , with a high performance-price ratio. Using ordinary multi-mode…
