Abstract :
We describe a method to study dense wavelength-division multiplexed (DWDM) transmission over amplified links that have no inline dispersion compensation and where the channels have nearly 100% precompensation. The approach is based on two recirculating loops that are linked to each other. Using this apparatus, we demonstrate DWDM transmission of 16 nonreturn-to-zero 10-Gb/s channels on a 50-GHz grid over links ranging from 320 to 1280 km of standard single-mode fiber with precompensation values ranging from -5440 to -21 760 ps/nm.
