Abstract
A new design is proposed to enhance an existing architecture for delivering future millimeter-waveband (mm-WB) Radio-over-Fibre (RoF) for wireless services with the use of Dense Wavelength Division Multiplexing (DWDM) architecture over a Passive Optical Network (PON). For the conceptual illustration, we deployed the original DWDM RoF-PON system then redesigned its infrastructure. In the downlink, the mm-WB RF signal is obtained at each Optical Network Unit (ONU) by using optical Remote Heterodyning Detection (RHD) between two optical carriers simultaneously, which is generated using a single laser source. The generated RF modulated signal has a frequency of 12.5 GHz. Such RoF system is simple, cost-effective, low-maintenance and is immune to laser phase noise in principle.
