In this paper, we have explained the implementation of the channel guard algorithm which validates the newly added channels in the colorless reconfigurable optical add drop multiplexer (ROADM) system before ramping up their power in the ROADM network to avoid the interference with the existing traffic-carrying channels.
Automatic channel power control loop is a dynamic scheme that continuously adjusts the variable gain elements and variable attenuation elements in an optical network to the changing network conditions. The firmware embedded in various modules continuously monitors the strength of the optical signals, adjusting the optical attenuator and amplifier gain in response to changing power and signal conditions...
