- 초록
- The applicability of clock and data superposed modulation for clock component enhancement in 40Gb/s NRZ signal was experimentally demonstrated. From this signal 40GHz clock was easily extracted by band-pass filtering. The result showed 0.5dB power penalty improvement with respect to a conventional clock extraction method of using non-linear circuits. It is also pointed out that relative amplitude and phase of the two superposed modulation signals are very important for good BER characteristics.
