“…Today FSO is commercially available in the market, supporting data rates up to 1.25 Gbps and are designed to work in almost all reliable atmospheric conditions over the link of 3.5 km. Efforts are continuously increasing in order to boost the capacity of FSO systems by using wavelength division multiplexing (WDM) and integrated fiber/ FSO transmission systems [23]. Orthogonal frequency division multiplexing (OFDM) is a mature technology for combating multipath fading in FSO.…”

Abstract:Complementing wireless radio networks with free-space optics (FSO) achieves high data rates by modulating radio subcarriers over an optical carrier without expensive optical fiber cabling, enabling a pervasive platform for reaching underserved areas. In this paper, we review the main features of FSO for terrestrial and inter-satellite communications. Simulations of 1 Gbps data transmission through FSO links in both terrestrial and inter-satellite communications have been investigated to highlight potential atmospheric challenges in FSO.

“…The next-generation FSO systems [1,3] can provide even a higher data-rate and capacity. Those types of systems are based on transmitting an optical beam over an atmospheric link that, afterwards, it will be directly coupled into an optical fiber core.…”

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.

“…Experimental investigations on the next generation FSO systems utilizing transparent connections is a further step in the present optical wireless scenario, focused on opaque systems that will give access to the virtually infinite fiber bandwidth [6,7]. The possibility to merge FSO and PONs now represents a fundamental step in the next generation networks (NGN) deployment, especially in situations where the last mile is mainly copper based and the costs for a fiber deployment are too high.…”
