Abstract

We report the field demonstration of 100-Gb/s real-time coherent optical orthogonal frequency-division multiplexing (CO-OFDM) detection using polarization division multiplexed QPSK modulation per subcarrier. The paper includes one of the lowest BER ever reported for a CO-OFDM back-back transmission experiment at $5\times 10^{-9}$ and the successful 495.2-km transmission over mixed types of field installed fiber. The field trial is conducted in a dispersion managed WDM system with neighboring 10-Gb/s Ethernet channels.
