Abstract
A method of operating a WDM transmission system with at least one transmitter and at least one receiver connected by means of a dispersive transmission line. The proposed method comprises the successive steps of successively: a) setting a tunable dispersion pre-compensation value at a transmitter-side Tunable Dispersion Compensation Module in operative connection with the transmitter to a first predetermined value (PRE°); b) setting or adjusting a tunable dispersion post-compensation value at a receiver-side Tunable Dispersion Compensation Module () in operative connection with the receiver to a second value (POST°) in order to optimize at least one characteristic (monitored performance like BER, eye opening, Q factor BER) of a transmitted signal at the receiver; and then c) simultaneously tuning the transmitter-side Tunable Dispersion Compensation Module and the receiver-side Tunable Dispersion Compensation Module with opposite respective dispersion shifts in order to further optimize said characteristic of the transmitted signal.
