Abstract

The small form factor chirp-managed laser (CML) source at 1550 nm was used in conjunction with postdetection electronic signal processing to successfully achieve transmission over 1200 km of nonzero dispersion-shifted fiber in a dense wavelength-division-multiplexing environment, without using any optical dispersion compensation. In a comparative study, the dispersion tolerance and the transmission performance of the CML were found to be better than the duobinary format.
