In this paper we present an in-home optical network infrastructure based on 1 mm core diameter graded-index plastic optical fibre. A combined transmission of a multi-gigabit baseband data stream, based on discrete multitone modulation, and a radio frequency signal, based on ultra wideband technology, is shown. A detailed experimental study on the performance of the two types of signals in the combined...
In-building networks delivering broadband wired and wireless services can be realized cost-effectively with duplex plastic optical fibre, particularly when sharing ducts of electrical power cabling. Point-to-point architectures are well-suited for residential buildings, and bus or star-bus ones for larger buildings.
By using optical fibre, a single in-building network can offer many broadband services to both wired and wireless terminals. Multi-level modulation and dispersion-robust radio-over-fibre techniques allow the use of cost-effective multimode silica or plastic fibre.
We present, both numerically and experimentally, the nonlinearity effect of the intensity modulator in RoF transmitters through the comparison between single-carrier QAM and multi-carrier OFDM signals. The acceptable RF power level of the multi-carrier OFDM signal is 2 dB less compared with the single-carrier signal for the same EVM penalty of 1%, indicating the degradation due to inter-modulation...
Advanced optically-emulated x-QAM techniques and the modal dispersion-robust radio-over-fiber OFM technique enable the delivery of high-capacity data via a single multimode (silica or polymer) optical fiber in-building network to wired as well as wireless terminals.
