摘要：
The paper investigates a novel multi-band coherent optical orthogonal frequency division multiplexing (CO-OFDM) PON architecture, aiming to deal with the phase noise compensation due to the dispersion of optical signals in long-range transmissions. Our approach is to manipulatively allocate dispersion compensating fiber (DCF) and local oscillator (LO) laser phase shifter for each end-to-end transmission between OLT and ONU. Simulation of the downlink traffic between one optical line terminal (OLT) and 12 optical network units (ONUs) is performed successfully at different fiber lengths, at the data rate of 10Gbps per ONU. The required BER for the forward error correction (FEC) has been achieved for the most ONUs using a dispersion compensating fiber (DCF) and local oscillator (LO) laser phase shifter to compensate for the chromatic dispersion (CD) and the polarization mode dispersion (PMD), respectively.
