Abstract
A power equalization system and method for use in an optical transmission system are provided. The power equalization system includes an optical line including at least one transmission channel and a management line. The transmission system further includes a plurality of amplifiers, a plurality of Optical spectrum analyzers and a plurality of equalizers. The plurality of amplifiers are coupled to the optical line, spaced periodically throughout the optical transmission system. As information is sent through the optical transmission system, the plurality of amplifiers boost the power of each channel of the optical signal. A plurality of optical spectrum analyzers are also coupled to the optical line and are spaced periodically throughout the optical transmission system and are co-located with a first portion of the amplifiers coupled to the optical line. A plurality of equalizers are also coupled to the optical line and are spaced periodically throughout the optical transmission system and equalize the power on each channel of the optical line. The plurality of equalizers are co-located with a second portion of the plurality of amplifiers and at least one of the plurality of Optica…
