We propose and demonstrate a 10-Gb/s dense wavelength-division-multiplexing (DWDM) optical system based on a pulsed-seed-light source employing a fiber-based Mach-Zehnder interferometer (F-MZI) as an intensity noise suppressor. The transmission results show that the required injection power into a reflective modulator was as low as -18 dBm. The F-MZI can accommodate the polarized seed-light with superior noise characteristics so that the supported DWDM systems double using a single conventional unpolarized seed-light. In addition, an allowable length of the drop fiber is investigated to show the system flexibility.
我们提出并演示了一种基于脉冲种子光源的10 Gb/s密集波分复用(DWDM)光学系统,该系统采用基于光纤的马赫曾德尔干涉仪(F-MZI)作为强度噪声抑制器。传输结果表明,注入反射调制器所需的功率低至-18 dBm。F-MZI能够容纳具有优异噪声特性的偏振种子光,从而使支持的DWDM系统在使用单个传统非偏振种子光时翻倍。此外,还研究了下路光纤的允许长度以展示系统的灵活性。
