We demonstrate a single-wavelength, 344-Gb/s, 43-Gb 16-quadrature amplitude modulation (QAM) polarization division multiplexed signal transmission over 800 km operating below the hard-decision forward error correction (FEC) BER threshold of 3.8 × 10-3 using an InP dual-polarization in-phase/quadrature modulator. At the receiver, a simplified single-ended coherent receiver with novel digital signal processing (DSP) for self-beating noise removal is employed. Compared with the conventional single-ended detection, this signal processing method doubles the propagation distance and increases the SNR by more than 1 dB. In addition, this DSP method provides 10 dB of the received optical power dynamic range while operating below the hard-FEC BER threshold of 3.8 × 10-3, compared with the no dynamic range for a single-ended receiver without the proposed DSP. |
