Frequency conversion in optical fiber allows for coherent optical processing of densely multiplexed subcarriers in spatially separated nodes. Proof-of-concept experiments show the applicability to up to 32QAM subcarriers, broadband operation (400 GHz) and selective processing of PDM subcarrier tributaries.
