Abstract
Using a powerful postamplifier, a remotely pumped preamplifier, chroma tic dispersion compensation and forward error correction, a repeaterle ss transmission distance of 461 km has been achieved at 8 x 2.5 Gb/s. This experiment demonstrates the possibility of using launch signal po wers in excess of 1 W when the chromatic dispersion compensation is op timized to minimize nonlinear impairments. In addition, 377 km has bee n achieved by replacing the remotely pumped preamplifier with a distri buted Raman preamplifier.
