Abstract

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 within the network. This ability to monitor power levels ensures power equalization across all wavelengths and minimizes data bit errors.
