“…FSO systems are mostly used for line-of-sight applications, thus offering similar capabilities as optical fiber communications with attractive features including a huge bandwidth, no licensing fee, inherent security, low cost of installation and maintenance, and immunity to electromagnetic interference [1], [2]. Data rates R d up to 10 Gbps are readily available in commercial FSO systems operating over a link span of few kilometers [3] and up to 1.6 Tbps over a 80 m single outdoor link based on the dense wavelength division multiplexing technique was reported in [4].…”

“…We measured λ β using (2) corresponding to the measured T from light to dense fog condition for all wavelengths. The link visibility is measured simultaneously with the λ β along the length of the chamber at 0.55 µm wavelength using (1). Note that, the goal of the experiment is to characterise the attenuation, identical powers at different wavelengths are not essential.…”

“…The FSO communications are attracting attention as the contemporary technology to solve the last mile bottleneck issues in local area access networks due to their high bandwidth, low cost implementation in a non-licensed spectrum, relatively lower power consumption and immunity and security compared with RF technologies [1][2][3]. However, the constitution of the atmosphere, particularly, aerosols (fog, smoke, dust) have similar particle size distributions compared with optical wavelengths in FSO.…”

“…Commercial FSO systems can operate at data rates R up to 10 Gbps [3,4] over transmission span of a few kilometers. The data rate can be further increased by employing the wavelength division multiplexing (WDM) technique reaching 1.6 Tbps over a short link span of couple hundred meters [5,6].…”

Error mitigation using RaptorQ codes in an experimental indoor free space optical link under the influence of turbulence

Abstract:In Free space optical (FSO) communications, several factors can strongly affect the link quality. Among them, one of the most important impairment that can degrade the FSO link quality and its reliability -even under the clear sky conditions -consists of optical turbulence. In this work, we investigate the generation of both weak and moderate turbulence regimes in an indoor environment to assess the FSO link quality. In particular, we show that, due to the presence of the turbulence, the link experiences both erasure errors and packet losses during transmission, and also compare the experimental statistical distribution of samples with the predicted Gamma-Gamma model. Furthermore, we demonstrate that the application of the RaptorQ codes noticeably improves the link quality decreasing the packet error rate (PER) by about an order of magnitude, also offering -in certain cases -an error free transmission with a PER of ~ 10 -2 at Rytov variance value of 0.5. The results show that the recovery rate increases with the redundancy, the packet length and the number of source packets, while decreases with increasing data rates.
