Fiber Optical Modem

Model: NT-277 Series

RS 232/485/422 Serial Port Fiber Optic Modem

Overview

NT-277 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 kilometers. NT-277 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.
