optical fiber cable is transmit the signal in form of
light,it will be measure such a instrument is OTDR .
RTU - stand for remote terminal unit . it collects all data
from the field , in field numbers of rtu is availble and
send a signal to one MTU. MTU is stand for Master Terminal
Unit which give signal to scada computer is Supervisory
Control Data Aqusition system.
