RS485/RS422/RS232 Fiber Modem | Mini Type

View : 465
Type : Serial Optical Fiber Modem
Description :

This device is based on FPGA which supports asynchronous RS-232/422/485 communication interface Fiber Modem.

Overview

This device is based on FPGA which supports asynchronous RS-232/422/485 communication interface Fiber Modem. The device is the best choice for connecting the remote terminal unit (RTU) to a host (HOST) or a distributed data acquisition system (SCADA) controller with a very high-performance price ratio. Using ordinary multi-mode fiber effective communication distance is up to 2KM while using ordinary single-mode fiber effective communication distance is up to more than 120KM. The 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 of harsh environments lightning, surges, electromagnetic interference, and other communication devices while eliminating the investment in surge lightning protection devices when the original use of copper.
