| 1. An apparatus for testing and optimizing performance of an optical transmission system including a transmitting terminal
for transmitting a plurality of wavelength division multiplexed optical signal channels in an optical bandwidth of said transmission
system, a receiving terminal for receiving said plurality of optical signal channels, and a fiber-optic transmission span
having an input fiber and an output fiber, both coupled between the transmitting and receiving terminals, the apparatus comprising:
at least one broadband dispersion compensation unit (DCU) coupled to the fiber-optic transmission span, said broadband DCU
being configured for selectively adding a common amount of dispersion compensation across said optical bandwidth and for performing
a dispersion sweep by varying the dispersion compensation of at least two of said optical signal channels in a series of steps.
