Simultaneous transmission of broadband wired and wireless signals over 50 m 1mm-core GI-POF is demonstrated for the first time. 2.2 Gbit/s DMT and 528 MHz 200Mbit/s UWB wireless signals are delivered with BER <; 10-3 and EVM <; <;15.5, respectively, in accordance with WiMedia standards.
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 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 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.
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.
With the optical frequency multiplying technique, high-capacity radio-over-multimode fiber networks can be realized for in-building applications. Dynamic wavelength routing provides extra network flexibility for e.g. delivering capacity-on-demand, and can be realized with optical wavelength conversion.
We demonstrate a novel technique for generation and transmission of IR-UWB signals over 100-m 50-mum core GI-POF. IR-UWB pulses are made by linearly combining two first-order derivatives of Gaussian pulses with different pulse-shaping factors.
We demonstrate a novel technique for generation and transmission of IR-UWB signals over 100 metres 50-mum core GI-POF. IR-UWB pulses are made by linearly combining two 3rd-order derivatives of Gaussian pulses with different pulse-shaping factors.
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%.
The transmission of 64 QAM radio data signals with a data rate up to 150 Mb/s through long single mode fiber links at different frequencies has been experimentally evaluated. The system under study uses the optical frequency multiplication technique for the generation of carriers in the microwave and millimeter-wave bands. Transmission using frequencies of 18.7 GHz, 19.5 GHz, 19.7 GHz and 29 GHz is...
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.
Radio-over-fiber technologies enable efficient provisioning of broadband wireless services both in access and in in-building networks, in particular when combined with flexible optical routing and dispersion-robust RoF transport techniques, such as optical frequency multiplying.
Optical fibre is marching fast towards the user's doorstep, as witnessed by the many new Fibre-To-The-Home installations. The next challenge is to disclose the power of optical communication inside the home, so to bring the full broadband potential to the end user. The presentation will describe the latest advances in our research into low-cost in-home techniques, encompassing techniques for service...
