“…In the last decades, free-space optical (FSO) communication systems are receiving considerable attention [1][2][3][4][5][6][7][8] especially thanks to their inherent potential transmission capacity, much higher than that offered by radio transmission technologies. In addition, their narrow beam widths and their inherent license-free operation allows FSO systems to become appropriate candidates for secure, high-data-rate, cost-effective, wide-bandwidth communications.…”

A new and generalized statistical model, called Málaga or simply M distribution, has been derived recently to characterize the irradiance fluctuations of an unbounded optical wavefront propagating through a turbulent medium under all irradiance fluctuation conditions. The aforementioned model extends and unifies in a simple analytical closed-form expression most of the proposed statistical models for free-space optical (FSO) communications widely employed until now in the scientific literature. Based on that M model, we have studied some important features associated to its fade statistics and expressed in terms of the expected number of fades per second. The derived expressions become relevant for many aspects in a FSO system, especially those ones related to determine the optimum threshold in a receiver based on a direct detection scheme employing a fixed detection threshold.

“…Concretely, FSO systems can be applied for metro-access network extension, last mile access, enterprise connectivity and, additionally, it presents interesting applications in the development of trunk links in metropolitan area networks (MAN). Such systems are also used in hybrid radio on free-space optical (RoFSO) or in all-optical hybrid fiber communication systems [1,2]. Considering their narrow beam widths and its inherent license-free operation as compared with microwave systems, FSO systems are appropriate candidates for secure, high-data-rate, cost-effective, wide-bandwidth communications.…”

Abstract:Light beams can carry orbital angular momentum (OAM) associated to the helicity of their phasefronts. These OAM modes can be employed to encode information onto a laser beam for transmitting not only in a fiber link but also in a free-space optical (FSO) one. Regarding this latter scenario, FSO communications are considered as an alternative and promising mean complementing the traditional optical communications in many applications where the use of fiber cable is not justified. This next generation FSO communication systems have attracted much interest recently, and the inclusion of beams carrying OAM modes can be seen as an efficient solution to increase the capacity and the security in the link. In this paper, we discuss an experimental demonstration of a proposal for next generation FSO communication system where a light beam carrying different OAM modes and affected by M turbulence is coupled to the multimode fiber link. In addition, we report a better and more robust behavior of higher order OAM modes when the intermodal dispersion is dominant in the fiber after exceeding its maximum range of operation.

“…Ro-FSO technology is the combination of radio over fiber (RoF) and free space optics (FSO) [1]. The main advantage of RoF is the ability to distribute the RF signal at large bandwidth using optical fiber at lower attenuation, immunity to RF interference and low power consumption.…”

Radio over free space optics (Ro-FSO) technology provides a promising solution for future wireless network, offering high data transmission compared to RF technology. In this paper, performance of double sideband-suppressed carrier based Ro-FSO system under various weather conditions is investigated. It transmits two RF signals at 10 and 15 GHz over an optical wireless channel of 1 km. At transmitter Mach Zehnder modulator is used for both carrier suppression and signal modulation. At the receiver, delay interferometer is used for separation of RF signal having delay of 0.1ns. KeywordsRadio over free space optics (Ro-FSO), RoF, FSO, ODSB-SC, Wavelength interleaving (WI).
