Abstract

We present a 60 Gbit/s polarization-multiplexed coherent optical OFDM transmission at 5 Gsymbol/s by employing 64 QAM subcarrier modulation. We adopted a frequency-stabilized fiber laser and an optical PLL to achieve this high multiplicity in the subcarrier modulation. As a result, we successfully transmitted 60Gbit/s data over 160km with a demodulation bandwidth of only 5.3 GHz.
