Abstract

This paper proposes and demonstrates the use of filtered microwave band‐pass windows situated at 2.1 and 4.2 GHz as electrical carriers to transmit digital signals. The use of an appropriate microwave photonic filter (MPF) allows for the generation of the microwave band‐pass windows. The key parameters of the filtering effect are the intermodal separation of a multimode laser diode (MLD), the chromatic dispersion parameter of the optical link, and its own length. Experimentally, it is demonstrated that the filtered band‐pass windows can be used as electrical carriers to transmit digital signals at frequencies of 50, 100, and 150 MHz over 25.31 km of single‐mode‐standard‐fiber (SM‐SF). The quality Q‐factor, jitter, and bit‐error‐rate are the parameters that allow for the evaluation of the quality of the digital signal transmission. The obtained results allow for the proposition of this photonic architecture in a passive optical network (PON) to distribute services like Internet Protocol (IP) telephony, internet, streaming video, and high definition television.
