AbstractThis article experimentally demonstrates a hybrid fiber–free-space passive optical network that enables high spectral density, aggregated capacity, and total throughput through ultra-dense wavelength-division multiplexing baseband and radio-over-fiber channels. Ultra-dense wavelength-division multiplexing 10-Gb/s Nyquist-shaped 16-ary quadrature amplitude modulation, 10-Gb/s radio-over-fiber orthogonal frequency-division multiplexing, and 8.75-Gb/s baseband orthogonal frequency-division multiplexing signals per user were transmitted through a maximum 40-km passive optical network, which includes a 6-m free-space optics link with acceptable performance.Keywords: advanced modulation formatsfree-space opticsoptical access networksultra-dense wavelength-division multiplexing–passive optical network Additional informationNotes on contributorsAli ShahpariAli Shahpari received his M.Sc. in electrical engineering–telecommunications (in 2003) from Shiraz University, Iran.
