This technical repot reviews the presentation of the ECOC2018 Postdeadline Paper Th3B.3. We use 368 PDM-256-QAM 24.5GBd signals and high-granularity FEC to achieve 1.2Pb/s throughput on a 3.37km few-mode multi-core fiber with 12 spatial channels and the lowest cladding diameter fiber (160 micrometer) to demonstrate Pb/s class transmission.
