Abstract
We show that the minimum EOP (eye-opening penalty) obtained by tunable
dispersion compensation is a function of a figure of merit for a nonlinear process,
I<sub>0</sub>L<sub>eff</sub>, where I<sub>0</sub> is the
optical intensity and L<sub>eff</sub> is the effective length of
the interaction region. Using this rule, we do not need to conduct nonlinear
simulations in all the cases of signal power and transmission length to obtain the
signal distortion in dispersion-managed optical transmission. Instead, we need to
conduct a simulation in only one case of a signal power and find the functional
relation, and then we can obtain the values of the signal distortion in other cases
using the discovered functional relation. This technique can reduce the number of
nonlinear simulations to less than 10%.
