OFDM modulated WDM-ROF system based on PCF-Supercontinuum.
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.
