WDM Transmission systems based on SOAs and alternative modulation formats

摘要

Using POLSK (POLarization Shift Keying) and DPSK (Differential Phase Shift Keying) formats we fully exploit Semiconductor Optical Amplifiers (SOAs) for signal amplification in practical WDM Nx10 Gbit/s systems. Record transmission experiments are presented, thus making SOAs a competitive amplification alternative in metro and extended-metro networks.
