“…enterprise network and building‐to‐building connection) [2], and their advantages over fibre installations including cheaper and easier deployment and network flexibility [2, 3]. Although FSO communications are adversely affected by atmospheric turbulence (optical scintillation), FSO systems employing wavelength division multiplexing (WDM) technology have been investigated experimentally focusing on enhancing the user and data carrying capacities, network reach and ultimate commercialisation of such systems [2, 4]. In previous analyses that were primarily focused on the average bit error rate (BER) of such a system, it was shown that the effect of interchannel crosstalk which is common in WDM systems is exacerbated by atmospheric turbulence in WDM FSO systems, particularly in the upstream transmission [5, 6].…”

“…FSO communication systems have been widely applied in inter‐satellite and deep space communications and have recently received more interest in terrestrial communication with specific applications, such as pre‐deployed backup link, rapidly deployed disaster recovery link and enterprise connectivity, e.g. LANs and wide area networks [2, 4, 7]. Such systems provide extra flexibility and relative ease of upgrade as the user need changes, and have increasingly been proposed as promising solutions to high‐speed transmission in the last mile of optical access networks [8].…”

“…Wavelength‐division‐multiplexing (WDM) system has application in both optical fibre and FSO systems [1, 2, 4]. With WDM PON, fixed wavelengths are assigned to each optical network unit (ONU), thus more fully exploiting the high‐transmission bandwidth available in the optical domain and avoiding the synchronisation and threshold acquisition required in the burst mode upstream of time‐division multiplexing/time division multiple access (TDM/TDMA) systems [13, 14].…”

A hybrid fibre and free space optical (FSO) communication link using digital pulse position modulation (DPPM) in a wavelength division multiplexing (WDM) system is proposed. Such a system, which could provide a power efficient, robust and flexible solution to high speed access networks, is a contender for a passive optical network (PON) solution and could readily be deployed in areas with restrictions in optical fibre installation, or alternatively as a disaster recovery network. However, the effects of interchannel crosstalk, which is common in WDM systems, and atmospheric turbulence-induced scintillation, limit the performance of such system. Both impairments, which could combine in some cases to further degrade the system performance, are investigated here. Specifically, the symbol error probability, the required optical transmission power and power penalties are derived. Furthermore, the required performance of the demultiplexers in terms of adjacent channel rejection is studied with respect to the FSO link length. A simple relationship between the turbulence attenuation and crosstalk 2 is derived to facilitate demultiplexer selection in the design and analysis of practical systems without forward error correction (FEC) coding. Results also show that DPPM systems are more power efficient than OOK systems in the presence of crosstalk accentuated by atmospheric turbulence.

This 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 radioover-fiber channels. Ultra-dense wavelength-division multiplexing 10-Gb/s Nyquistshaped 16-ary quadrature amplitude modulation, 10-Gb/s radio-over-fiber orthogonal frequency-division multiplexing, and 8.75-Gb/s baseband orthogonal frequencydivision 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.
