Abstract:
1. A method of dispersion management, the method comprising: configuring a controller to determine, based on a location of an intended optical receiver, whether or not a fiber-optic link between an optical transmitter and the intended optical receiver is an inhomogeneous link, including determining whether or not the fiber-optic link has a first portion characterized by a first effective dispersion-coefficient value and a second portion characterized by a second effective dispersion-coefficient value that is smaller than the first effective dispersion-coefficient value by a factor of at least 1.5; and further configuring the controller to select, if the fiber-optic link is an inhomogeneous link, an amount of dispersion pre-compensation based on dispersion characteristics of the first portion and the second portion of the fiber-optic link; and configuring the optical transmitter to apply said amount of dispersion pre-compensation before an optical transmission to the intended optical receiver.
