The future never works out quite how you planned. After introducing 100G coherent technology into core and submarine networks, product design engineers now lust for a progression of proprietary coherent interfaces for the metro sector, enabled by falling component costs and higher-order modulation schemes that decrease the cost per bit of the physical interfaces.
