The COFFEE project aims at demonstrating, through field trial experiments, the coherent optical data transmission of a single superchannel at the high capacity of 1Tbps using a reduced bandwidth (<200 GHz) over long-haul testbed routes.
Innovative techniques, already developed in a laboratory, will be introduced in a field trial environment. Time-Frequency Packing (TFP) will be used to increase the spectral efficiency. With respect to other commonly used techniques like orthogonal frequency division multiplexing (OFDM) and M-ary quadrature amplitude modulation format (M-QAM), TFP can guarantee for lower transceiver complexity and bandwidth requirements, higher tolerance with respect to fibre propagation nonlinearities, reduced power consumption, and larger flexibility.
Techniques developed within the COFFEE project will play a key role in the forthcoming standardised communications, increasing network flexibility and capacity.
