在这份报纸,一个新毫米波浪(公里波浪) 波长部门 multiplexing (WDM ) 系统基于 radio-over-fiber (ROF ) ,技术被建议。在这条途径,多波长光来源被 supercontinuum (SC ) 获得技术,和公里波浪信号被使用光外差获得方法。我们试验性地为 6-WDM 隧道表明光搬运人的产生,由采用光 heterodyne 技术获得 40 个 GHz 公里波浪信号,并且成功地完成在在在 G.652 纤维的 25 km 的距离上的 WDM 隧道的 2.5 Gbit/s 的低误差率传动。试验性的结果证实建议答案可行、合算。
In this paper, a new millimeter-wave (mm-wave) wavelength division multiplexing (WDM) system based on radio-over- fiber (ROF) technology is proposed. In this approach a multi-wavelength light source is obtained by supercontinuum (SC) technique, and mm-wave signals are obtained by using optical heterodyning method. We experimentally demonstrate the generation of optical carriers for 6-WDM channels, obtain 40 GHz ram-wave signals by employing optical heterodyne technique, and successfully achieve low error rate transmission of 2.5 Gbit/s in WDM channels over a distance of 25 km in a G.652 fiber. The experimental results verify that the proposed solution is feasible and cost effective.
