中文摘要：
监视技术的所有光的即时色彩的分散(CD ) 被建议并且为调音的 40 Gbit/s 微分阶段移动(DPSK ) 表明了信号，利用半导体的生气调整效果光放大器(SOA ) 。输出的光力量光谱部件，从直到信号带宽的探针频率，被用于 CD 监视。这种技术向一个宽监视范围提供大变化规模。极化模式分散(PMD ) 和监视结果的 CD 上的光 signal-to-noise 比率(OSNR ) 的影响理论上被分析然后试验性地调查了，证明他们有对在某个范围以内的监视结果的细微影响。而且，为照阶段移动调音模仿了结果，显示这种技术也对先进调制格式合适(QPSK ) 在 80 Gbit/s 的信号是也示威了。
英文摘要：
An all-optical real-time chromatic dispersion （CD） monitoring technique is proposed and demonstrated for 40Gbit/s differential phase-shifts keying （DPSK） signal, utilizing the cross modulation effects of semicon- ductor optical amplifier （SOA）. The optical power of the output spectral components, which is from the probe＇s frequency up to the signal bandwidth, is used for CD monitoring. This technique provides a wide monitoring range with large variation scale. The impacts of the polarization mode dispersion （PMD） and the optical signal-to-noise ratio （OSNR） on the CD monitoring results are theoretically analyzed and then experimentally investigated, showing that they have slight influence on the monitoring results within a certain range. Furthermore, simulated results for quadrature phase shift keying （QPSK） signal at 80 Gbit/s are also demonstrated, indicating that this technique is suitable for advanced modulated format as well.
