Wired/wireless access integrated RoF-PON with scalable generation of multi-frequency MMWs enabled by tunable optical frequency comb.


In this paper, a novel wired/wireless access integrated radio-over-fiber passive optical network (RoF-PON) system that utilizes scalable multiple-frequency millimeter-wave (MF-MMW) generation based on tunable optical frequency comb (TOFC) is proposed. The TOFC is performed by cascading a phase modulator (PM) and two intensity modulators (IMs), and with proper selection of the peak-to-peak voltage of the PM, a flat and effective optical comb with tens of frequency lines is achieved. The MF-MMWs are generated by beating the optical comb line pairs with an interval about 60 GHz. The feasibility and scalability of the proposed wired/wireless access integrated RoF-PON scheme are confirmed by the simulations of simultaneous distribution of wired and wireless data with the proposed multiple frequency MMW generation technology.
