Application of performance monitor using pre-scaled clock-tone detection technique to 160-Gb/s RZ-BPSK signal and 40-Gb/s NRZ-OOK signal

The performance monitoring technique using pre-scaled clock-tone detection was proposed and the principle of the technique was explained. The technique has advantage of simple contracture with very low electrical bandwidth. In addition, applicability of proposed techniques to 160-Gb/s RZ-BPSK signal and 40-Gb/s NRZ-OOK signal was discussed. In spite of the lack of clock-tone spectra in BPSK signal, the proposed technique generates the pre-scaled signal and is able to detect waveform distortion by chromatic dispersion and OSNR degradation. Furthermore, possibility to separate the distortion origin of 40-Gb/s NRZ-OOK signal was reveled by adding revealed 25-ps and 12.5-ps delayed interferometer.
