It is well known that fiber-radio schemes merge the high speed of the optical links with the wide-coverage and mobility features of wireless systems. In this regard, we present the performance evaluation of a hybrid fiber-radio communication system for video distribution operating in the S-band. We demonstrate experimentally the generation of a series of microwave passband windows over 0.01–10GHz range obtained by the interaction of an externally modulated multimode laser diode emitting at 1.55µm associated to the chromatic dispersion parameter of an optical fiber as well as the length of the optical link. Also, demonstrated experimentally is the transmission of TV-signal coded on the microwave signals located at 2.27GHz and 4.54GHz, its propagation over an optical link of 25.24km, and finally its distribution to multiple users by using an antenna. The originality of this work resides in the fact that the filtered microwave signals used as electrical carriers are function of the distance between the central site and the antenna; therefore it is possible to assign a particular microwave passband for certain services. Experimental results allow us to demonstrate that the Fiber-To-The-Antenna scheme is a promising technique for multiservice distribution. •Mathematical analysis of the frequency response of a microwave photonic filter.•Use of a microwave photonic filter for long-haul transmission.•Transmission and distribution of TV coded on filtered microwave signals.•Use of the chromatic-dispersion parameter of the optical fiber for filtering effect.•Distribution of video over a FTTA architecture in the frequency range of microwaves.
