We propose and experimentally demonstrate a monocycle ultra-wideband (UWB) generator adaptable to an optical network where dynamic capacity assignment is implemented. It is based on two-tap microwave photonic filter by using phase inversion in a Mach-Zehnder modulator which provides negative coefficients in the equivalent microwave photonic filter. The insertion of a variable delay line in the system...
In this paper, a novel transmission configuration for SCM/WDM radio over fibre communication systems is proposed and experimentally demonstrated. The scheme is based on the spectrum slicing of a low-cost optical broadband source to obtain a set of optical channels compatible with WDM technology. In order to increase the frequency operation range limited to hundreds of MHz due to the fibre dispersion...
In this paper we propose a novel photonic transceiver based on the phase modulation of an optical broadband source sliced by an Mach-Zehnder interferometer which is suitable for radio over fiber applications. The SCM data signal is introduced in the optical fiber link by the photonic transceiver at the Central Office. After propagation over 20 km of a dispersive SMF link, a CWDM performs the spectral...
A Fabry-Perot based filter enables a low bandwidth saturated SOA to implement a wavelength reuse scheme for upstream links featuring combined transport of wired and wireless signals. The architecture is experimentally demonstrated in this paper.
In this paper a new low-cost SCM-WDM scheme suitable for short/middle-reach multimode radio over fiber applications is proposed. The approach is based on the spectral slicing of an optical broadband source centred at 1550 nm and a Mach-Zehnder interferometric structure used to increase the operative frequency range up to 20 GHz. Free-error transmission for QPSK and 64-QAM digital signals over a 20...
