We demonstrate a proof of concept real time HD video stream delivery over 50m 1mm core diameter plastic optical fiber and 3m wireless link employing MB-OFDM UWB technology for in-home networks.
We demonstrated an all-optical up-conversion of Multiband OFDM UWB signal employing optical frequency multiplication technique. After transmission over multimode fiber, the performance of the spectral mask and error vector magnitude are compliant with ECMA standard.
The first multi-standard transmission consisting of 6 Gbit/s DMT baseband and 200 Mbit/s MB-OFDM UWB radio signals over 100m perfluorinated graded-index plastic optical fibre is demonstrated. Transmission performance indicates BER <; 10-5 and EVM <; -22dB respectively.
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...
A WiMedia-compliant MB-OFDM UWB transmission system is demonstrated, using low-cost transceivers, over up to 50 m long 1 mm PMMA graded-index plastic optical fibre. UWB signal is downconverted to intermediate frequency and transmitted over graded-index plate optical fibre with an overall error vector magnitude penalty 7 dB.
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...
