108 Tb/s Transmission Over 120 km of 7-Core Multicore Fiber with Integrated Cladding Pumped Multicore Amplifiers

Abstract

By employing time-domain hybrid modulations we maximize the throughput over a multicore fiber link. Modulation scheme ratio is adjusted according to the available OSNR at each spatial and wavelength channel achieving a net spectral efficiency of 39.27bit/s/Hz after 2×60km transmission.
