Abstract
A coordinated method is provided for controlling dynamic gain equalization in an optical transport network. The method includes: detecting a deviation in optical power of an optical signal traversing the optical transport network along a transmission path, adjusting spectral profile of the optical signal at a first network element in the optical transport network, where the first network element is located in the transmission path downstream from the origination point of the deviation; and adjusting spectral profile of the optical signal at a second network element subsequent to the adjustment at the first network element, where the second network element is located in the transmission path downstream from the origination point and the first network element.
