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...
We present the first experimental demonstration of full-duplex, bidirectional transmission of WiMedia-compliant ultra-wideband (UWB) signals at 200 Mb/s over 100-m perfluorinated graded-index plastic optical fiber (POF) with 50- core diameter. Error vector magnitude penalties of 1.2 dB and 2.1 dB are achieved for up- and downlink transmission, respectively.<?Pub _bookmark Command="[Quick...
We present the experimental study on dynamic capacity allocation in radio-over-fiber based on SOA optical routing. One-dimensional dynamics using optical routing as well as two-dimensional dynamics by optical routing and electrical SCM are demonstrated.
We investigate photonic packet switches that allow scaling to a large number of input and output ports. The suggested switch architectures are based on technology that has already been demonstrated. We focus on a simple Spanke node architecture. Scalable, low latency optical packet switches sub-systems capable to switch optical packets with multiple modulation formats are reviewed. The optical packet...
We present a scalable and low latency optical packet switch for DPSK and OFDM packets. Results show error-free operation of 1 ?? 64 optical packet switch for 12 ?? 10 Gb/s DPSK packets and 12 ?? 40 Gb/s OFDM packet.
We address the successful transmission and optical dynamic routing of high capacity RF data using an SCM or OFDM format over multi-mode fiber links, by the means of optical frequency multiplication.
We report record transmission systems of ultra-wideband MB-OFDM signal over 50-m 900-mum core graded-index PMMA POF using low-cost VCSEL at 667 nm. A gross bit rate of 2.1 Gbit/s is achieved with BER < 10-3.
We report a radio-over-fibre system for all-optical routing OFDM signal at 18.3 GHz over 950 m multi-mode fibre, with error vector magnitude penalty <3%.
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...
