Abstract

  • This paper proposes the provision of quintuple-play services (high-speed wired data, voice, high-definition audio and video, wireless data and security and domotic applications) employing only orthogonal frequency division multiplexing (OFDM)-based radio-over-fiber (RoF) optical transmission in a deep fiber-to-the-home (FTTH) passive optical network. The different wireless signals form a RoF bundle comprising DVB-T signals for TV broadcasting, an LTE signal for voice, a WiMAX signal for wireless data supporting management and home security applications, and UWB for high definition audio and video distribution. An I/Q OFDM signal is also included in the bundle providing wired Gigabit Ethernet (GbE) connectivity.
    The complete RoF bundle is managed and transmitted from the central office through a deep fiber-to-the-home network integrating the access, the in-building and wireless links. The RoF bundle permits the transparent transmission through the optical access network and, once in the building, is further transmitted optically to reach deep in the customer premises where LTE, WiMAX and UWB signals are photodetected, amplified and radiated. The in-building network considered uses bend-insensitive single-mode fibre (BI-SMF) in order to be able to install it in the building while keeping the transmission characteristics of standard fibers. The proposed approach also permits broadcasting DVB-T signals through the legacy coaxial network if present in the building, including in addition power-over-coaxial provision.
    This unique RoF bundle approach permits converged and hybrid service provision, i.e. high-definition audio and video service can be provided simultaneously through DVB-T, UWB or WiMAX technology, wireless data can be provided by I/Q OFDM, LTE or WiMAX. Finally, this paper reports the results of the open-house show-room demonstrator for the quintuple-play service provision after deep FTTH distribution in a real network and the user feedback gathered.
