TS-RS232-fiber is a type of RS-232/RS-485/RS-422 serial port fiber optic Modem. It adopts industrial standard design

and its wall type outface design supports DIN-rail standard lead rail installation, featuring easy installation. Presently,

many users make use of RS-232/RS-485/RS-422 serial port fiber optic Modem to solve the electromagnetic interference

in engineers and to extend the RS-232/RS-485/RS-422 serial port transmission distance to several or even tens of


TS-RS232-fiber can provide users with RS-232/RS-485/RS-422 serial port end-to-end 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
