We have proposed a novel orthogonal frequency division multiplexing (OFDM) modulated WDM radio over fiber (ROF) system by employing a single photonic crystal fiber (PCF) supercontinuum (SC) multi-wavelength lightwave source. Both wired and wireless applications of ROF access are achieved. In our experiment, we pick out four 40-GHz ROF channels by properly designed fiber Bragg grating (FBG). The 1-Gb/s 16QAM-OFDM downstream signal is demonstrated for both wired and wireless applications over 20-km standard single mode fiber (SMF). A 1-Gb/s OOK upstream signal is also transmitted over 20-km SMF successfully with less than 0.4dB power penalty.
我们提出了一种新颖的正交频分复用（OFDM）调制的光纤无线（ROF）系统，该系统采用单光子晶体光纤（PCF）超连续谱（SC）多波长光源。实现了ROF接入的有线和无线应用。在我们的实验中，通过适当设计的光纤布拉格光栅（FBG）选出了四个40GHz的ROF信道。在20公里标准单模光纤（SMF）上，针对有线和无线应用演示了1Gb/s 16QAM-OFDM下行信号。一个1Gb/s的OOK上行信号也成功地在20公里的SMF上传输，功率代价小于0.4dB。
