Abstract
Methods, media and signals for determining optimum pre compensation in an optical system. A first method involves receiving a pre-compensation ratio value representing a ratio of dispersion and length to optimum pre-compensation, for a span of optical medium in said optical system and producing a system precompensaton value as a function of dispersion and length of each span in said optical system such that differences between actual pre-compensation and optimum pre-compensation in each span of said system are minimized, A second method involves producing an optimum pre-compensation value P.sub.wdm by balancing power profiles in the positive and negative chirped regions of the system, for pulses emitted into an optical medium of the system. A method of optimizing performance of an optical system, using pre-compensation is also disclosed.
