Optical delay interferometer(ODI)-based optical frequency equalization is applied to mitigate chirp and dispersion induced impairments,so that the tolerance to inter-symbol interference(ISI) can be enhanced, thus enabling 4 × 25 Gb∕s on-off keying(OOK) transmission per core over severely limited bandwidth channels. Real-time bit error ratio(BER) performances of the bidirectional 400 Gb/s transmission are measured without using extra digital signal processing(DSP) or electrical equalization, which ensures low complexity and less power consumption.显示全部
