Dispersion compensation over an 18-nn bandwidth is achieved with a module o
f three chirped fiber gratings. Five of these grating modules are demonstra
ted in the 32-channel WDM transmission of 10 Gbit/s NRZ signals over 375 km
(five amplified fiber spans) of conventional fiber. Results from the sweep
of a tunable 10-Gbit/s signal in 0.1-nm steps across the 18-nm bandwidth c
onfirm good performance across the entice band.
