Summary:
Space-division multiplexing (SDM) systems have been extensively proposed during recent years to achieve transmission throughput above 1 Pb/s [1]. These experiments typically demonstrate aggregate spectral efficiencies (SEs) above 100 bit/s/Hz [1] and make use of fibers with large cladding diameters to ensure acceptable inter-core crosstalk levels [2]. In [3], we demonstrated 1.2 Pb/s throughput using a 4-core, 3-mode, few-mode multi-core fiber (FM-MCF) with a cladding diameter of 160 ??m. This demonstration has shown petabit per second throughput using a fiber with a cladding with a diameter less than 200 ??m, which was achieved using 368 spatial super channels (SSCs) with 12 spatial channels (SCs) each and carrying 256-QAM signals across C and L bands. To exploit the available capacity of the system, we employed SD-FEC with codes from the DVB-S2 standard, which were punctured for a code rate granularity of 0.01.
