Experimental demonstration of colourless, directionless, contentionless ROADM using 1×43 WSS and PLC-based transponder aggregator for 127-Gbit/s DP-QPSK system

We demonstrate a colourless, directionless, contentionless ROADM consisting of 1×43 WSSs and PLC-based transponder aggregators. The experimental results show that the introduction of a C/D/C-less function causes no significant penalty for 127-Gbit/s DP-QPSK signal transmission.
