中文摘要：

基于过滤的自我阶段调整和通带显示计划的一个新奇所有光的小点错误被建议。在这个计划，放大的原来的位流通过自我阶段调整发生的高度非线性的纤维宣传，然后通过一个通带过滤器被变换成显示信号的一个小点错误。在显示信号的小点错误，错误小点有最高的山峰力量，和 '1' 和 '0' 位有更低的。同时，显示信号的小点错误与推迟的原来的位流是同步的。因此，在原版的错误位的位置咬了流能被将一仅仅法官阀值放在显示的位错误识别信号。这个计划的表演被模拟与 return-to-zero 格式为 80 Gb/s 小点溪流表明了。结果证明建议计划能被用于与 return-to-zero 格式超级高小点率系统显示的所有光的小点错误。

英文摘要：

A novel all-optical bit-error indicating scheme based on self-phase modulation and band-pass filtering is proposed. In this scheme, the amplified original bit stream propagates through a high-nonlinear fiber where self-phase modulation occurs, and then passes through a band-pass filter to be converted to a bit-error indicating signal. In the bit-error indicating signal, the error bit has the highest peak power, and the ＂1＂ and ＂0＂ bits have lower ones. At the same time, the bit-error indicating signal is synchronous with the delayed original bit stream. Therefore, the position of the error bit in the original bit stream can be identified by setting only one judge threshold in the bit error indicating signal. The performance of this scheme has been demonstrated for an 80 Gb/s bit-stream with return-to-zero format by simulation. The results show that the proposed scheme can be used for the all-optical bit-error indicating of the super high bit-rate systems with the return-to-zero format.
