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

Employing time-domain hybrid modulation we maximize the throughput over a multicore link of $2\times 60km$ . We adjust the ratio of the modulation schemes according to the available OSNR at each spatial and wavelength channel achieving a net spectral efficiency of 39. 27bit/s/Hz.
