Paper Abstract

For the first time, we experimentally investigated and demonstrated waveband switching for 100 Gb/s DWDM system with high spectral efficiency of 3.4 b/s/Hz. 3 adjacent 25 GHz-spaced 114 Gb/s PolMux-RZ-8PSK channels are grouped as a waveband to be switched and transmitted through 4 WSS-based ROADM nodes. Error free transmission is achieved with little filtering effect observed even after 4 ROADM nodes. The transmission performance shows that waveband switching based on WSS can be used in high spectral efficiency DWDM systems. This can reduce the switching hardware cost and operation expense in highly dense WDM systems.
