All across the world, the number of 100G network deployments is growing. Mostly done in the network service providers’ core network, the objective of these deployments is either to add capacity or aggregate multiple existing 10G services. In such scenarios, the lineside uses coherent 100 Gbit/s transmission to reduce the signaling rate while maintaining the 100G data rate. This is achieved using advanced modulation techniques, like DP-QPSK, on channels within the DWDM network.
