Transmission performance of the simplified receiver for 2×PDM-PAM, CAP and DMT signals
2020
Abstract Based on the two polarization-division-multiplexing jointed intensity modulation and direction detection (2 × PDM-IM/DD) system, the performance of the simplified receiver is studied for alternative intensity modulation formats such as PAM-4, CAP-16 and DMT. At bit rate up to ∼ 2 × 112-Gbit/s, compared with the single polarization signal, experimental results show that the power penalty of 2 × PDM-PAM-4, CAP-16 and DMT is ∼ 0.8-dB, 1.2-dB and 1.3-dB (back-to-back) at 7% forward error correction (FEC) threshold, respectively. The transmission (i.e. 25-km non-zero dispersion shift fiber) penalty is 1.8-dB, 1.4-dB and 1.7-dB for the corresponding modulation formats. Furthermore, the comparative analysis of the simplified receiver among the three modulation formats is carried out.
