Experimental evaluation of transmission between two xbee modules using radio-over-fiber technique

Abstract:

An experimental transmission between two XBee modules using Radio over Fiber technique is demonstrated. Data issued from an XBee module coded on a wireless microwave carrier at 2.44GHz is transmitted through an optical link of 25.24 km. The optical transmission is based on an external modulation scheme over a dispersive channel. Frequency response of the external modulation scheme is determined by simulation and experimentally. In particular, the chromatic dispersion of the optical fiber associated to its length allow the generation of a pass-band filter whose bandwidth is used to code the RF signal. The recovered RF signal exhibits a SNR of 27dB. Obtained results allow proposing this RoF scheme as a good contender for data transmission.
