We report a novel low-cost in-home broadcasting system using a 1-mm core graded-index plastic optical fibre split network reaching up to 35 meters. We demonstrated broadcasting 2.5 Gbit/s data to four end-users employing discrete multi-tone modulation.
We propose novel generation technique of IR-UWB pulse by linearly combining two monocycles using different pulse shapes. We experimentally demonstrate DSP based BER measurement of 2 Gbps IR-UWB over multimode fiber for in-building networks application.
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.
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.
