Cascade of 4 SOAs with 448 Gbit/s (224 Gbit/s) Dual Channel Dual Polarization 16QAM (QPSK) for High-Capacity Business Paths in Converged Metro-Access Networks

We demonstrate 448 Gbit/s (224 Gbit/s) dual channel DP-16QAM (QPSK) transmission over four cascaded, linear SOAs using advanced modulation formats. As an application we envision dedicated high-capacity business paths in future converged metro-access networks. ©2012 Optical Society of America OCIS codes:250.5980 Semiconductor optical amplifiers; 060.0060 Fiber optics and optical communications.
