In this paper, we experimentally demonstrate a hybrid fibre-free space passive optical network that enables high spectral density, aggregated capacity and total throughput through ultra-dense wavelength-division-multiplexing (UDWDM) baseband and radio-over-fibre (RoF) channels. UDWDM 10 Gb/s Nyquist shaped 16-ary Quadrature Amplitude Modulation (16QAM), 10 Gb/s RoF Orthogonal FrequencyDivision Multiplexing (OFDM) and 8.75 Gb/s baseband OFDM signals per user were transmitted through up to 40 km Passive Optical Networks (PON), which includes 6 m Free-Space Optics (FSO) link with acceptable performance.
