considered to be a key device in WDM transmission systems for fiber loss compensation and for the provision of an optical network with almost unlimited coverage [1]. However‚ the EDFA has a non-uniform gain spectrum that restricts its usable amplifier bandwidth. The amplification of a WDM signal by a non-equalized EDFA may result in signal distortion and poor signal-to-noise ratio performance. Several methods‚ either intrinsic or extrinsic‚ have been proposed to equalize the EDFA gain spectrum. Intrinsic

home‚ an alarm will go off and the police will be alerted immediately. The transmitter section continuously transmits IR rays which are received by the receiver section. The received signal is further amplified and given to the PLL section‚ where its frequency is locked to the transmitted frequency. When the IR signal is interrupted‚ the microcontroller starts working as per the program burnt into the EPROM and control the siren‚ telephone and cassette player via the respective relays. CONTENTS:

Communication has always been important with in the military from day one. Wihtout this communication no soldier would know where to be or when to be there.
