UT168SM-SC20A/B

RS-232/485/422 Serial to Fiber Converter Single mode Bidi fiber SC 20km 1310/1550nm

(FC/SC/ST Connector optional )

1. Overview

Model UT168 series is a sort of more function and economy RS-232/485/422 interface optic fiber MODEM. It is the best choice to connect RTU to HOST or SCADA controller. It used Optic fiber as transfer medium, increase the transfer function of system. Communication equipment abstain menace effective to lightning strike, surge, electromagnetism disturb under the scurviness environment.

2. Function and Characteristic
