Abstract

We demonstrate an IM/DD IFoF transmission system using a DML for the delivery and generation of 4.25-Gbit/s OFDM quantum-noise randomized QAM cipher at an IF of 1.875 GHz. The simplified setup achieves truly random quantum-noise signal masking for preventing interception while maintaining high signal quality.
