RS232/RS485/RS422 industrial fiber modem
Overview
modem is a type of RS232/RS485/RS422 serial port fiber optic Modem. It adopts industrial standard design and its wall type outface design supports DINrail standard lead rail installation, featuring easy installation. Presently, many users make use of RS232/RS485/RS422 serial port fiber optic Modem to solve the electromagnetic interference in engineers and to extend the RS232/RS485/RS422 serial port transmission distance to several or even tens of kilometers. TBCmodem can provide users with RS232/RS485/RS422 serial port endtoend transparent transmission. Since signals are transmitted over fibers and these optical signals are free of electrical conductivity, they have strong anti-interference capacity and are immune to high-voltage power or thunders.
