Higher capacity with smaller global energy consumption in core optical networks due to elastic channel spacing

We propose a novel model for core optical networks combining benefits of transparent and opaque networks through variable channel spacing. We demonstrate increased capacity at limited energy cost through detailed transmission experiments and network planning.
