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…

How to choose a signal isolator?

Analog isolator is an electronic component used to isolate analog signals between two circuits to prevent interference between circuits. It usually consists of two analog signal converters, which can convert analog signals into digital signals and then convert them back into analog signals to achieve isolation. Signal isolator is a kind of linear optocoupler isolation…
